Guitarman, thanks for your help. With your settings I have become very content with the hd-72. Some of the noise issues I was having also had to do with the dvd quality. Bit of a mistake to judge the entire projector on a single dvd transfer. Rookie mistake! After playing a dozen movies or so most transfers are good to very good. Hd is awesome as well as the xbox360.

Yes Xbox 360 looks great but addicting (Ghost Recon) will drive you mad. :)

Glad the picture's working out.

I narrowed my purchase to a H72 but a box store in canada has the Optoma H78DC3 on for a good price what is the difference in quality, features, pq etc? Is it worth the extra $
Thanks Steve

Glad the picture's working out.Guitarman are you running it straight to the 72 or through a switcher

Hi all,
I've noticed the recent great deal being offered for the hd72 in the US and I am willing to ship to Australia. Its about double the price here. Unbelievable rip off it is. The Ausie unit is the HD72i which I'm sure many of you well know. So does it matter if I have an American unit I think there is some DCDI chip in the Australian model. Do I need this? I can see the specs support 240 volts and PAL so I think I'm ok but I'd feel better if someone could reassure me. I also understand that warranty will be a major issue should something go wrong so is it the general consensus that the HD72 is a reliable model without any common defects like lamp etc?

Component switching with a HK7300 receiver for the Xbox and Comcast HDTV feeds. HDMI for the Panasonic S97. I also ran a DVI cable with a HTPC with good pictures results accept HTPC's can have the worst deinterlacing.

Well, I kind of have my 35' DVI from computer to projector problem figured out. A little embarrassing really, but at the same time it's more of Optoma's fault. :o The first HD72 that I had to send back because of the bad frame buffer(that's what the tech called it) was the one I actually tested DVI on. I was reminded over the weeked that I had never actually tested the DVI on the replacement unit. Well, there you have it...the DVI doesn't actually work on this unit. Anytime the projector finds a source on that port it will lock up. I used the DVI port on the previous projector for many hours and on a wide variety of resolution/refresh rate settings. I tried a DVI -> HDMI converter and the image looked incredible.

Solution: Sent it back? Nah...if DVI is the only problem, I'm not that concerned. I'll simply use a HDMI 4 port switcher. There are a lot worse problems I could be having with this projector other than a port I can easily get around using. (dust blob, reset issues, noisy color wheel, unfocused optics, choroma bug, fan problems, the frame buffer problem that only i seemed to have experienced, etc.) Nothing can be perfect, so I'm a fan of working around something where it's specific problems don't bother you much. lol...same thing applies to women. :rolleyes:

Oh, there are so many crude responses one could make to that post.

Sorry if this has been covered earlier in this 1758 post thread, but I just have a quick question. When you guys are getting these new are the RGB gains and biases set to something other than zeros for the HDMI input? Just trying to figure out if the one I've seen had been tweaked as they were not zeros and looked like they had been modified.

Thanks,
Darin

Darin, what wasy your impression of the one you saw?

With all the talk of latest firmware, can someone post what number it is. I went back a few pages and didn't see it anywhere. I may have missed it though.

Thanks,

The preset white balances already have configurations, they're not stock at zero. I did make changes from the factory settings to get more exact to D65 plus 2.2 gamma. The PC gamma got closest to 2.2 over the others.

I spent way too much time today going through all the links....wheew.

Dear AVS members,
DONT BUY AN OPTOMA HD72 OR SEND IT BACK FOR REPLACEMENT!
FAST351, they are intentinally delaying me! Ive been waiting for my tracking number since Friday and I have yet to recieve it. The incredibly rude and idiotic customer service ppl could not give less of a cr*p about me or my business and Ive been told to contact the better business bureau but not sure how to do that. FAST351 REPORTED THAT HIS INFORMATION ON THE RMA WAS WRONG, MINE WAS TOO. MY ADDRESS WAS MISSPELLED AFTER FILLING OUT THE SAME INFO TWICE AND WITH CLEAR HANDWRITING . Coincidence? i.e. Optoma sux. In addition, I was on hold for a half an hour waiting for cs to pick up, which they did not. Khara, the one who "filled" out my information doesnt answer the phone. They lost me as a customer and I am getting ready to cancel the charge and send it back if they ever ship it to me. This unprofessional behavior leads me to believe that they will stoop to any level instead of owning up to responsibilities. Why not tell me that you have no units available? That lie is more believable than ignoring your customer and intentionally screwing up information to delay repair. This also makes me not trust them and think that they might stoop even lower and try to send me a refurbished unit or any hd72 model they have lying around. Is there anyway to check to see if it is truly a brand new unit? This kind of scummy behavior should not be tolerated and I will never purchase an optoma product again. If anyone has suggestions about what they would do in this situation or recomendations about the IN76, plz let me know. Can I get Projector People involved? Ive wasted 15 hours reading reviews for this unit if all Im going to do is send it back and go for the IN76 which I know nothing about or how it compares to the HD72. I was very happy with the unit until this treatment. ---Faithful and mad AVS fan. Spencer

Sorry to hear ofyour problems with Optoma CS. I dealt with Robert S. and my experience was exactly the opposite of yours. I had my new unit in 5 days.

I finally called Visual Apex and told them the whole story and let them sort it out. I strongly suggested they either quickly resolve it or they're getting the unit back. Seems like Sheryl at VA has a contact at Optoma and got the ball rolling. The unit is SUPPOSED to ship out today (although after 7 days of being told that, my hopes are low).

The bottom line is their customer service stinks. If I didn't like the projector so much I would have already told them to shove it and sent the unit back.

Typical for CE customer service I guess.

Speaking of problems, does anyone else have a high pitched whine coming from their unit? Mine does (although a replacement is supposedly coming, so....) and it's pretty noticable.

Oh well, hopefully this will be a better week for getting a new projector. If it's not here by Friday I'm ditching it and going to an InFocus IN76.

I just received my unit the other day and while it is much quieter then my old 4805 I do hear a high pitched whine. Anyone else hearing this also? I was hoping it would go away with a little use but after watching a couple of movies it is still there.

-Dennis

I do hear a slight high pitched hum(not that noticable). I heard it from both HD72s I've used. With a 2 for 2, I feel I can safely assume it's going to be on all of them....or at least the majority. What is the most likely candidate? The color wheel or power supply? I ask other people if they can hear it, before and during a movie, and nobody else but myself can hear it. Then again, I look for things to complain about just for sake of complaining... ;)

It is not noticable at all while watching a movie, but just knowing its there, I find myself listening for it. Overall, even with the slight whine, it is much quieter then the 4805.

That's a good point that I didn't make, and yeah, I listen for it a lot too. The fan and high pitched hum are neither one that noticable. I can't hear either one during a movie or when listening to music. Speaking of which, gonna have to watch Apollo 13 again tonight....looks awesome on HD-DVD. :D

So is anyone here able to just watch a movie in your HT just for the sake of watching a movie? There is probably an equation for the amount of time it takes after upgrading/buying equipment before you can just enjoy it. :rolleyes:

I think you're right, it does take a while to actually just enjoy something. Although I watched CSI Miami last night in HD and that show just rocks as far as colors goes. I think it's probably the best HD fodder on network television.

To tell the truth, despite the couple small shortcomings, I love the projector. The whine is only noticable because I basically sit right below the projector and I can hear it when it spins up. Once the volume is at a reasonable level, it's not noticable.

One thing I should mention. The offset thing is blown WAY out of proportion in this thread. I have a total of 12" of offset from the center of the lens to the top of the screen, and there is ZERO noticable optical keystoning on a 106" screen. And since the screen is 52x92 and a 16:9 picture is actually slightly wider, a 1/4" on either side of the picture drops into the border anyway if you want to fill the screen vertically. I actually have about a 1/4" on the top and the bottom of the screen into the border (equivalent to roughly 2 pixel rows) and about 1/2" on either side (about 4 pixel rows).

The projector is pointed slightly at the ceiling to make this offset happen. I'm sure I could get quite a bit more aggressive before the optical keystoning became an issue.

Solution: Sent it back? Nah...if DVI is the only problem, I'm not that concerned. I'll simply use a HDMI 4 port switcher. There are a lot worse problems I could be having with this projector other than a port I can easily get around using.

Aha ! That's the exact problem I've got ! Can't get DVI to work. Well, it worked for 30 seconds then lost the signal then hung. Now never finds a signal on that port anymore. Sounds like it's a known potential issue. As yourself I'm not sure if it's a 'biggy' - HDMI works a treat and 90% of the use is for Xbox360.

I have been watching this thread for some time. I bought this unit last month, and am very happy, no resets and working great. The remote control has always been weak at best. Press a button and only get a flicker of Button lights and only sometimes works. Last night I decided to change out the batteries, after which it would not work at all. I looked very closely at how the batteries are installed in the remote, The new Energizer batteries have a slightly thicker decorative wrap on the outside ( and specifically on the very end) of the battery. This thicker wrap was enough to cause the positive end of the battery to not make a good (or any) contact with the inside of the case. The original batteries (thinner decorative wrap) made a little better contact, but still not sufficient. I took a little stripped copper wire and built up the positive ends of the battery compartment , and it works better than it ever has. I know others have discussed poor IR reception, and I understand Optoma has made ir improvements. I wonder if others are having remote problems like this, the difference is night and day.

M4tt, do me a favor if you will. Set your resolution going into DVI to 800x600@~70Hz and let me know what you get...or are you not able to do that on a 360? I ebay'd a couple for quite a bit of a markup since they were the pre-christmas premium package shipment, but I've never actually used one. ;)

I got mine to work on 800x600@60Hz barely(image just flashed on and off a few times), 70Hz wasn't bad, and 72 or 75hz worked nicely. Any other resolution would make the projector lock up. I don't know about you, but I don't like the idea of continuously causing expensive devices to lock up or malfunction without having FRUs or a spare unit laying around. So...I can't see myself doing any more troubleshooting on this issue. haha

I'm finishing my basement, and I'm thinking of going projector rather than LCD or plasma mainly for the asthetics and picture size for the money. I don't know much about projectors, but from what I've read, the Optoma HD72 is the best for the money. This looks EXTREMLY tempting: ebay auction ID 9721588643 What does everyone think about this deal?? Should I jump on it?

:eek: <-- is my exact facial expression during, and after, reading your post. That seems really strange, but I guess worth a shot. I can't even imagine how bad of a connection something would have to have too allow the lights to light up, but not allow the IR to transmit strong enough.

Jlatenight,

You're in the same situation I was in when I remodeled my basement just recently, and I'd have to say I'm really happy I went with a projector...specifically the HD72. That does look like a good deal, and not that I care, but some seem to frown upon direct linking to auctions or websites selling...anything.

Right now, most of the major projector AVS sponsors are offering a free bulb with the purchase of this projector. The bulbs retail for $399 so its a pretty good deal that is hard to pass up if this projector is on your short list.

Thanks Derrin. I guess I could have been more general saying "inexpensive projector bundles on ebay". I'm just concerned with warranty, so I sent them an email confirming it's US-based. Anything I should be worried about with these types of bundles? I'm not tooconcerned with the quality of the screen as long as it's not all wrinkled or something. Thanks all! -Jon

Hi there, my xbox is just going direct into the component ports. It's my Oppo DVD that won't work thru the DVI in any of its modes (480p, 720p, 1080i). Well, it worked for 30 seconds or so before the pj went a bit gaga.

Matt

Sounds like a problem to me. I've ran all common signals into both the HDMI and DVI ports on my HD72 and it doesn't seem to have any problems. Sources include an HTPC, LG LST4200A OTA box, and a Samsung HD-850 DVD player.

-Mike

will this projector work with my enviro?

room size is 10' w x 23' L x 8' H
ceiling mount = 4" drop.
screen size 106"

My experience has been similar. The 2m DVI-D cable worked perfectly until I had left the pj on for about 20 minutes with no change from the computer (screen saver) at which time, the pj lost the signal. This happened a couple of times. The first few times, I just moved the mouse and the signal came back. The last few times, there was no change in signal and for one to be recieved, the computer had to be rebooted. This continued until (very quickly, no signal was recieved at all.) Optoma's shady CS ppl told me that he had heard of DVI-D problems involving the cable and suggested I change it. I bought a 30' blue jeans dvi-d dual link cable that is in the mail now and I hope to avoid this problem in the future. Seems to do with an unchanging picture and I will be extremely careful in the future. Please continue to post similar experiences so we can narrow down the problem until Optoma stops pretending that it doesnt exist.

It should. Realistically any mount will put the lens center 5" below the ceiling (using the Chief RPA-U anyway, that's where it lands).

My screen top is about 18" from the ceiling, which puts the screen bottom 26" off the floor. I find that a very pleasant screen location. The screen is about 5 inches higher than the mathematical offset with a level projector, and I cannot see any optical keystoning (although my CAD model suggests roughly 1/4" per side top to bottom).

If you want a drop down screen instead of a fixed screen, make sure you get a screen with additional blackdrop. Mine's a Dalite, and you can order it that way.

You can see my install here. (http://www.fast351.com/ht/ProjectorInstall/) Last picture shows current screen height.

You should have no problem. I have a 104" screen in a 22L x 13.5W x 8H room and have the top of the projector about 5" or so from the ceiling. My screen is around 21" off the floor.

I originally counted this projector out because of all of the "terrible" offset talk. Then I realized that my Infocus 4805 didn't have much less of an offset. A 8' ceiling should be a none issue with this projector.

Has anybody noticed or been able to recreate the horizontal chroma bug via. HDMI that the cine4home review found?

i m sure it will too. ordered it. should be here by early next week.

thanks you guys

I'm having a problem with my HD72. Three times in the past week when I powered down, the bulb turned off but fan speed did not increase. It also didn't turn off. It just kept on spinning as if the projector was still on. In order to get it to stop, I had to flip the on/off switch.

The only thing I can think of which I'm doing differently than before is using the HDMI input. If I'm not mistaken, all 3 times this has happened, it was locked to an HDMI signal which had been turned off first.

I did a search of this thread and couldn't find anyone with a similar problem, but has anyone encountered this?

Thanks,
Mike

I just noticed this same problem, I heard a fan running and realized it was the PJ, I powered it off an hour before, the fan was still running. This will be my second unit I have to get repaired I guess, how annoying. Anyone else notice this, it's likely a firmware bug, but of course unlike my Infocus we can't do our own updates.

Update: Someone plz help me. So far Ive been happy with one thing alone. The picture quality, when I can get it. Ive searched the forums for answers to this problem without success and posted an earlier complaint. A new unit hopefully will be shipped soon but I'm worried that the same problem will surface. The DVI input shows no signal on screen. Ive swapped the dvi-d cables 2x. This new one is a 30' blue jean cable. Ive also swapped video cards 2x to see if the dvi port was just shot. This card is an older geforce 4400 ti and still no signal.

However, the software from nvidia picks up the hd72 and even names it hd72 as a second monitor (the other just worked b4 and didnt show multiple monitors). Ive rebooted many times, Ive changed the resolution on the hd72 to 800x600 and 75~ refresh rate as someone earlier suggested to matt's problem- without success.

I'm hoping that the new projector with that firmware solves this but it only seems to address the reset and hddvd player issues. I still get no signal on this unit (unless I use a degraded svideo signal) and I'm at my wits end. What do I do now? What if the new unit has the same intermittent problems? Am I doing something wrong? What made the DVI all of a sudden stop working? Someone please help. Id be very grateful and you would save me so much time, energy, and frustration. Thank you all for your time. Spencer

Hi there - are the video cards using the digital or analog part of the DVI output ? If they're digital then I'd suggest trying a DVI->HDMI cable. I reckon that will work, especially if you choose a 720p 60Hz style resolution. I've a feeling there's a DVI-D issue going on with the HD72. My DVI input worked ok with the analog output of my PC's DVI connection. It's just digital that's failing. Mind you, it could be that DVI-A has since broken, but it certainly used to work, I just use my Oppo instead now as it's soooooo much more convenient.

Hi, I've tried the 480i and 720p at various resolutions and refresh rates with no success. Nvidia reports the second monitor as digital and its a dvi-d cable. Not sure if the computer is outputing digital but I can't imagine why not if it says it is :) Which Oppo are you using? Everyone seems to be recomending the oppo dv971 but with the faroudjia chip already in the unit, I keep thinking that the oppo with that same chip won't make much difference in quality. Thanks for the response. Spencer

There's only one Oppo AFAIK, the DV971. I wanted a DVD player that had a digital connection as I'm using the component connection for my Xbox. As you've got a digital output on your card I'd definitely suggest trying a DVI->HDMI cable. My PC had a DVI output but it was only analog.

Gotcha. Thanks again. I'll get that oppo but I need my dvi-d to play. It doesnt make sense that it used to work and now it doesnt. Can't imagine that they would manufacture a dvi port on the back of a vid card and only output analoge but I guess its possible. Still doesnt explain why its acting tempormental though :) Think I'm going to wait to see when the oppo goes on sale as a refurb. 160+8 shipping +tax = about 181 shipping with the newest firmware from the oppo website vs. amazon for 200 even without knowing which version it is.Damn. I need that dvi to work. I watch so many things straight from the computer. What is wrong?

spencerfine,

I struggled with the same problem with an NVidia card. The only work around I have at the moment--and admittedly it isn't that good--is to turn on the projector, disconnect the DVI cable from the back of the PJ, then reconnect it. You should then be able to hit CTL+ALT+F8 to get the computer to sync with the PJ. This problem is specific to NVidia cards in my experience. When I connected with an ATI card, I had no problems at all. The problem appears to be related to the way NVidia addresses EDID information. Do a search in the HTPC forum for my posts and you will find several posts I've made about this situation. There are a couple of solutions suggested also.

EDIT: Here is a link to the best thread I found:

Slightly off topic but I was just wondering if anyone knew whether the Nintendo Wii's remote would work with my HD72...

Bum, now the HDMI input from the Oppo to the projector has failed in the same way (picture deteriorates and eventually the signal gets lost). So is that the Oppo or the projector ?

m4tt and Scm - Ive tried various combinations with both cards -ati and nvidia, without success. Both of the cards recognize the second monitor but the pj doesnt even work with only the dvi going to it and no vga hooked up. Ive tried the control alt F8 without success. The DVI-D seems to be recognized just not showing a picture. I am getting a new pj as soon as they get off their butts and send me one (been waiting for the tracking number since friday) but now I'm worried that this problem will manifest after a few weeks like this pj has. Ive tried in both cards to check and uncheck the EDID without result and disabled the nvidia service from msconfig that was also recomended. Thank you again for your support. I spent another couple hours on it today and now I'm not sure what to do :( Spencer

M4tt- It seems like your dvi cable might not be functioning properly. Is it overlength?. Good quality?

hmmm....why all of a sudden there are problems with the connection.

i just order mine. da mm it

have you folks notified optoma to let them know about the situation!!!!

if not let them know.

I use a gefen 4 HDMI to 1 DVI + digital audio switch into the DVI input of the HD72 using both the initial FW and the latest. I've never had an issue with the Oppo at all, and if I switch HD72 inputs direct to the HTPC (from component) without an EDID handshake it is corrupted. I get around it by switching gefen to the oppo and back to the PC to resync. An inconvenience, but liveable. I use an ATI 9200.

Ok i've been doing a lot of looking, I am really interested in the Optoma HD72 sounds to be a excellent projector for the price. This is my situation it will be in the living room so some ambeint light could play a factor during the day but i'm not worried bout it i can control the light, plus the HD72 seems to be very bright to start with .
The room is 15'x15' with a ceiling hieght of 8' the projector will be aprox. 14' from the screen or wall (which i don't have yet read somewhere you should get the proj. first then figure out your screen size so)... This is were i've been pulling my hair out trying to figure out if this proj. will work in this senario. I will be ceiling mounting it. I was thinking of just getting the HD72 and praying it works out, but i'm afraid something will arise.

Please help
Thanks Jasen

Hi Jasen,

Sounds like it will work but it depends on how big of a screen you want. Most of the offset complaints are from users who want to go larger than 106" 16:9 screen with 8ft or less ceilings. I have a 96" equivalent 16:9 screen with 7.5' ceilings and it's perfect for me.

Assuming ceiling mount, offset equals roughly 32% of the screen vertical down from the ceiling. For eg 106" screen will be roughly 22" down from the ceiling and 22" up from the floor (assuming a 5"offset for the projector from the ceiling). This puts right in the middle of the wall. Any bigger and the screen moves lower on the wall and smaller moves higher on the wall.

You can go bigger and tilt the projector although the image will be slightly trapezoidal. You can tilt the top of your screen slightly or use digital keystone to remove the trapezoidal effect. It's not an issue for most unless you want a really big screen - for which I'd recommend the IN76 as it as a smaller 16% offset.

Mike

Mike if you don't mind me asking what ceiling don't are you currently using with your hd 72...

Thanks Jasen

What about pressing the RE SYNC button? has anyone tried this?

M4tt- It seems like your dvi cable might not be functioning properly. Is it overlength?. Good quality?

I've tried the DVI cable that came with the Oppo (1.5m), plus a 7.5m one from Lindy (which was recommended). Niether got an image out of the Optoma for more than a few seconds before corrupting.

The thing is HDMI (which was previously totally fine) now corrupts as well - basically all the 'brighter' colours look mostly ok, but anything dark grey to black flashes from black to blue. After not too long at all it displays "no signal".

I've contacted Optoma and they said to return it for repair.

I've bought my Oppo into work to try out the DVI connection (and to elimiate it as the possible cause) on my monitor. Thing is I forgot the remote and my monitor (which takes DVI-D) doesn't like the resolution the Oppo switches to after the Oppo splash screen has been displayed (I might have left it in 1080i mode or something). So I'm off to a conference room to find a PJ to try out. Who knows, maybe it is the Oppo that is corrupt and the HDMI input was far more tollerant of the signal than the DVI input was.

Mike if you don't mind me asking what ceiling don't are you currently using with your hd 72...

Thanks Jasen

Ok i've been doing a lot of looking, I am really interested in the Optoma HD72 sounds to be a excellent projector for the price. This is my situation it will be in the living room so some ambeint light could play a factor during the day but i'm not worried bout it i can control the light, plus the HD72 seems to be very bright to start with .
The room is 15'x15' with a ceiling hieght of 8' the projector will be aprox. 14' from the screen or wall (which i don't have yet read somewhere you should get the proj. first then figure out your screen size so)... This is were i've been pulling my hair out trying to figure out if this proj. will work in this senario. I will be ceiling mounting it. I was thinking of just getting the HD72 and praying it works out, but i'm afraid something will arise.

Please help
Thanks Jasen


After reading this thread I was surprised when I hooked up my h72 at how much image shift is available when using 16:9 material. This was going to sit where my H31 was and I thought it should be close enough with a little modification. Well, I haven't measured it but the image shift allows you to go ~ 3.5" up and down so really you have about 7" of shift to play with from the base offset. A pleasant surprise after reading the threads. Made it super easy to setup. :)

Yeah, without that it's be a serious pain to set up. As is, it's only a modest pain in the ass. The only thing I'm not fond of is how the ceiling mount screws are not centered on the projectors center of gravity. The plastic on the base flexes enough so the projector isn't quite level. That means you have to adjust your mount to correct for the plastic flex.

I have never had any reset issue with my H72, watching a movie last night during reasonable weather, and the power goes out in the house. After a few hours the Power came back on, and my projector was reset, what was 75hrs lamp life was back to zero and the projection had to be changed back to ceiling mount. I would think this should not have caused the Lamp counter to reset. Anyone else experience a power outage with similar results.

I had a power outage once so far as well as unplugging it from power for about 24 hours, neither of which caused it to reset.

Although there is no firmware indicator in the menu near as I can tell, there is a way to tell which firmware you have:

There are only two firmware versions for this projector, according to Optoma.

V1, which has the reset problem
V2, which does not.

The way you can tell is by looking at the projection style icon in the menu. If you change the projection style to ceiling mount, and the icon in the menu still shows the front projection floor mount icon, you have V1. If it correctly shows the ceiling mount icon, you have V2.

Hope that helps.

Not so fast... I am on my second projector, a replacement for the resetting first HD-72 unit. This one "holds" its memory so far after three weeks, but the "projection style icon" is still "wrong" like the first one was. No resets with the second unit, so far. Fingers crossed.

I assume that I have the newer firmware (better have, or boy will I be pissed having to go for a THIRD HD-72 projector and also having missed out on the free bulb deal by just several weeks). But the projection icon method of verifying the firmware just isn't true in my case.

Hmmm, that suggests three revisions of firmware, which is not what Optoma told me, but entirely plausible.

Let us know if your settings go away.

You're probably right Mike. There's nothing that says every projector with original firmware has the reset issue(at least I doubt it). Maybe Timpanogos just got lucky! ;)

Have you guys with the DVI input problems unchecked all the other input boxes in the menu so that only DVI is selected? I just wondered if that made a difference for you.

I only use DVI so that is the only box I left checked. I don't want the PJ searching all the time especially when there is a pause from my cablebox.

hmm...seem to be a good suggestion. would someone give this a try later on tonite?

Well I tried my PC with a DVI-D output connected to the projector - and it worked fine. So I think it's the Oppo that is at fault - I guess the HDMI and DVI inputs are a bit different in tolerance of signal quality maybe. I guess one thing I did notice with the Oppo from day one - there was odd ghosting on the "Oppo" splash screen when the player started up. Is that normal ? On my TV it was a flat blue screen with Oppo written in white lettering, plus that white 'swirl'. On my PJ using the Oppo's digital output there was distinct ghosting with "Oppo" appearing faintly in the blue background in various places (and that's with whatever lead I tried).

Is there any successful Oppo DVI to HD72 pairing using a 25 ft plus DVI or HDMI cable? I am seriously thinking about getting the HD72 now that it's got an extra bulb and extra year of warranty. But I will be getting an Oppo DVD player as well.

Another question. If my OTA HD receiver outputs in 720P, does that mean I will bypass the HD72’s internal 540P to 720P scaling, if that’s what it’s doing? Or it’s better to have my OTA HD receiver output at 1080i and let the HD72 to do the scaling?

Hi there, I'm pretty sure the reviews on projectorreviews are done using an Oppo. Mine worked fine for a couple of weeks.

I run an Oppo and Moto cable box to a 2x switcher with 3' dvi/hdmi cables. Then run a 35' hdmi/dvi to the HD72. No sparkles...no issues, just a great picture.

Yes..if you are watching ABC you will get 720P direct with no scaling by either your STB or the HD72. If you are watching 1080i channels you either have your STB or the HD72 to scale it to 720p. The scaler in the STB may do the BOB so you really have to try each way to see what looks best and which has the better scaler.

I have an OPPO connected to my HD72 via 35-foot DVI-HDMI monoprice cable, and my DirecTV HD DVR connected via the same cable, but flipped around.

Both boxes work flawlessly, zero issues.

Hey, that's one way of working around an external switch! :-)

Hey all, I've had a search for this but didn't come up with much. My HD72 works with a 1280x720 60Hz signal from my PC over a DVI-D input - the PJ says it's a 1280x720 signal. With the Oppo outputing 720p the PJ identified the signal as 720p 60Hz. The PJ doesn't work with the Oppo anymore. Is there some way that a 1280x720 signal is utterly dissimilar from 720p signal such that the HD72 could be 'broken' for a 720p DVI signal, but still working for the 1280x720 PC signal ? Did that make sense ? I'm just making sure before I send the Oppo back. Optoma already said to send their projector back for a repair but that was before I discovered the Oppo doesnt work with the HDMI input anymore and before I discovered the PC works over DVI just fine.

Ramble mode off :)

It's the oppo. It has a notoriously weak DVI output voltage levels. That, coupled with a cheap DVI cable, will produce sparklies and even a complete drop of the signal. This is why your PC video card works and the oppo does not. Oppo tech support confirmed this for me.

I'd recommend trying a higher quality cable with thicker (lower guage) cable. I had this same issue and the better cable worked. DVI spec calls for no more than 15ft cable lengths, so anything beyond that you really need higher quality cables. Try and stick with thicker 22-24 AWG wires, thats usually how you can identify a better DVI cable. Avoid thin 30 AWG wires like the plague above 15ft.

A powered repeater or DVI switch will regenerate the signal which can also alleviate this issue - short cable from oppo to switch, long cable from switch to HD72.

Hi Uatatoka, thanks for the reply. I have to say even the short cable supplied with the Oppo (which looked nice and thick, obviously that's no indication of the gauge) didn't work for DVI->DVI. DVI->HDMI worked for quite a while over 6.5m. I suspect something has degraded a bit since then. I didn't get sparklies though - just major picture problems - I think in a previous post I said all the dark areas of an image would flash between black and blue, just imagine some 80's video with trick video effects and you'd be there.

I'm rather glad the PC worked thru DVI ok as the HD72 is rather fab and didn't want to send it back for 'repair'.

zboomer = what do u mean by "flipped around" the cable?


The OPPO has DVI output, and the satellite box (DirecTV HD) has HDMI output. The HD72 has a DVI input and an HDMI input as well.

When I was ready for the install, Monoprice was out of HDMI-HDMI and DVI-DVI cables both, so I just bought two 35' DVI-HDMI cables. I use one on the OPPO, with the DVI end connected to the DVD player, HDMI end connected to the HD72.

I use the same cable but "flipped around" on the satellite box. HDMI end is attached to the box, DVI end to the HD72. Both work perfectly. I've never had a single handshake problem, sync issue, dropout, or any other issues with either one. Note that I find the monoprice 35' cables very high quality. They are thick gauge, and have very nice connectors on the ends. Most impressive for the money.

I also ran an RG6 coax cable with RCA connector adapters on each end, to pass composite video from my receiver, for on-screen display. Cheaper (and probably better as it's shielded) than buying a long composite cable, since I have a couple spools of RG6 laying around. It also works great on the HD72.

I have to say though after working with these cables, physically DVI is a far superior connector to HDMI. They took a big step back going to the lame HDMI connector.

Any HD72 owners in the twin cities area willing to come over and do a side by side comparison with my IN76?

I have a universal mount (Chief) and can swap PJ's easy enough. Can also remove and do coffee table side by sides if necessary. Given the offset differences we would be limited in the ceiling mount tests.

Send me a PM if you have an HD72 and want to do the comparison. I am not willing to open this up to any other people to come and watch. I would also entertain an HC3000U owner (and their projector) also.

k

I'm sure you're all riveted with my ongoing Oppo/DVI/HD72 saga. Well I spoke to the people who supplied the Oppo and they said "sounds like the DVI board has gone, we've had a few customers with that issue - we'll send out a replacement board if you like ?" Sounds like a plan to me ! So anyone in the uk, I totally recommend itsupplies.co.uk for service :)

What's the best place to buy HD72 online? I've seen the current deals on VisualApex and ProjectorPeople. Which do you recommend based on your experience with customer service, etc. Are there any other vendors to consider?

Also I'm looking at 25 ft. HDMI-HDMI and Component cables. Who has the best price/quality on these?

Ron

I bought mine from Visual Apex and was happy with their customer service.

Most of my cables are from Blue Jeans Cables these days. They build the component cables themselves and are very high quality. I have one of their HDMI cables (30' version) and have no problems with it. Pretty hard to go wrong with BJC.

I got my projector from ProjectorPeople. I e-mailed one of their sales reps and told them I found an HD72 for like $100 less than ProjectorPeople offered it for and sent him the link. Told him I'd buy it the same day if he could make it happen....and so he did. He also went to the effort of having it drop shipped so I wouldn't have the reset issue. This was when the projector first came out. You guys buying now get a free bulb and a cheaper price on the projector...darn you! ;)

I have bought about 6 cables from monoprice. Very happy with them all, especially for the price. I got a 35' DVI-DVI cable recently and thought that it was having signal problems, but it was the DVI port on the projector instead. I converted it over to HDMI and it looks great.

I got mine from visualapex which came with a free lamp & additional 1yr warranty will arrive monday. all my cables was purchase from moneprice.com.

Hey all. Heres the deal with the 30 foot DVI-D cable. Once again It doesnt work with the new PJ.

Now I'm stuck buying an adapter or another cable from blue jeans or monoprice to see if the DVI-HDMI works. Can Someone recomend one or the other and tin, copper, gold? 24awg or 22, tin plated and copper what? what is that? Should I get an adapter for the previous 30 foot dvi cable to make it hdmi or is that shady and I should just get another cable? Any advice? I'd like to purchase it tonight if I hear some feedback.

Here are the links: I need one that is good qual and about 25-35 ft. I'm concerned about getting a crystal clear picture and not wasting money on signal boosters for a pure dig signal. Blue jeans looks a lot more expensive but they dont have any options for the copper and whatnot.

The only thing I can tell you is what works for me. I have two 30' cables from BJC. An HDMI-HDMI cable, and a DVI-HDMI cable. With the DVI and HDMI terminations at the projector, I have two HDMI connectors at my equipment rack. (This was on purpose, since these two ends needed to be pulled through a wall with insulation in it, and the DVI connector is way too big for that).

I have used both cables interchangably to feed three different devices to the projector, and none exhibited any problems.

My current setup is:

1) HTPC NVidia 6600 @ 1280x720 through a DVI->HDMI adapter, through the HDMI cable, into the HDMI port on the HD72. No problems at all.

2) LG LST 4200A OTA tuner @720P through an DVI->HDMI adapter, through the HDMI-DVI cable, into the DVI port on the HD72. Again, no problems.

One of the DVI/M to HDMI/F adapters is from Blue Jeans, the other from Monoprice. Both worth equally well.

I also tested the cables during initial installation from my Samsung HD-850 DVD player, using it's HDCP free HDMI port, on both cables. Although I only tested them about 10 minutes each for functionality, I didn't have any problems with that setup either.

I also have composite from my AVR through a 30' BJC RCA cable for it's setup screens, and component from the LG LST4200A, both of which work fine (the reason for the component is I will probably take the digital cable that's now being used and retask it to either an HD-DVD or BluRay plater in the future).

In short, I've had zero problems with any of the inputs on either the HD72 I just returned for a firmware upgrade or it's replacement in about 100 hours of use.

Yep! Jumped in with both feet...ordered Thursday nite. Seems the free shipping from Visual Apex is only in the US so I have to pay for shipping to Canada. But I get the extra bulb & warranty. Now to see how long it takes UPS to ship it & see how well it plays with my LG upconverting DVD player.
I'm SOOOOO excited. My poor X1 with1000 hrs on it doesn't know it's days are numbered!

Bud

Guys please let me know what projectors you're getting in regards to firmware right now.

I don't want to pull the trigger until they've sorted out this reset issue

I got mine last week from Projector People and I am pretty sure I have the latest firmware. I have not had any reset issues and I have my projector ceiling mounted and the style icon in the menu shows the projector being ceiling mounted.

-Dennis

Hey guys need help. I've tried the calculator but I am confused. My throw range will be 12-13 ft from screen and 9ft ceilings. Would a 106inch screen be okay for that? What is the range from 12ft? Does ceiling ht effect screen size and throw. Thanks

Calculator (http://www.projectorcentral.com/projection-calculator-pro.cfm)

At 12' you can throw an 87-105" screen

At 13' you can throw a 94-113" screen

I'd pick the screen size you want then pick the middle of the range for distance to give you the most flexibility.

I've got a 106" diagonal screen, so it appears the center of the projector's lens should be about 16.5' from the top of the screen. I can do 6" with my set up, and I figure another 2" by shifting the image within the 768 panel.

So, I'm going to be about 8" shy of where the projector's lens needs to be. Can I offset the keystoning I'd get by aiming the projector towards the ceiling by angling the screen back 1 - 2 inches, or would it have to be more than that?

Thanks for the help.

Message 1504 has installation dimensions specific to the HD72

http://www.avsforum.com/avs-vb/showthread.php?p=7459902&&#post7459902

Thanks Sueio. I understand the offset ratio and dimensions. My question is whether pulling back the bottom of my screen by 1 - 2 inches will be enough to offset the keystoning introduced by angling the projector upwards, as the projector would be hanging 8 inches too low.

SSJ2

Probably not. You need approximately 20" of offset. Instead of forcing it to work with a 6" offset, have you consider lowering the screen a little more and reducing the distance between the projector and the ceiling? See message 1402 on a simple mount. It puts the projector lens at only 4" from the ceiling.

Steve,

If your PJ is ceiling mounted, and you angle it upward to raise the image on the wall, you can tilt the top of the screen out (or tilt bottom back, if screen is hanging) to result in zero keystone error.

That's exactly what I've done, and it works great. I'd say it's tilted out about 2-inches. Added benefit is the screen angles down a little toward the viewer, so you have less keystone perspective.

Just for general reference, I believe that using the Tan of 6.52 to calculate the offset of a 16:10 screen is only applicable at a throw ratio of 1.96. It would have been nice for Optoma to write a web app to do these calculations. I tried to do them in a spreadsheet, but it was taking too long to attempt to derive info not listed in the manual like the offset angle at a throw ratio of 1.5. But I did find out that math is still confusing.

I narrowed my purchase to a H72 but a box store in canada has the Optoma H78DC3 on for a good price what is the difference in quality, features, pq etc? Is it worth the extra $
Thanks Steve

ZBoomer, this is exactly what I'm thinking of doing. How high is your projector mounted compared to the top of the screen, and how high do the specs say it should be?

Greetings all,

I joined the HD72 club this weekend and I'm giddy as a school boy!

My question - DVI or HDMI?

I read somewhere in this thread (though I can't find it now) that some have seen significant quality improvements with the HDMI and DVI over component. I'm looking to run a digital connection from an HD DTV Tivo box.

Can anyone speak to the image quality improvements? If so, any preference to connection type? Seems that HDMI may be the more stable option (with respect to connection and firmware). Also, any length concerns, I'm looking at 35-45 feet?

Thanks!

I have a 30' connection, and I can see a small difference between a digital and a component connection, but it's not necessarily a quality difference, I think it's more of a color difference between the two calibrations.

45 feet is definitely pushing the outer limits of a digital connection, but at 720P you'll probably be OK. Make sure you get high quality cable.

Warning to all potential Optoma HD-72 buyers: my first projector was purchased from Visual Apex on or about March 20 or so. Great company. Very friendly people. After arrival, the projector soon started to exhibit the "memory/settings loss" problem. I thought it was a fluke.

Called Optoma about mid-April after about six resets and evidence on this AVScience forum that this was not an isolated problem. Was on phone hold forever trying to reach Optoma. Without ever talking to a real person, I was finally bumped to a phone message bin where I left my name and number and waited six (6) days for a callback from them.

They shipped me a replacement projector on or about April 20. Now middle of May. The replacement projector shipped to me directly from Optoma is now showing the same memory loss/reset problem.

I have spent about three hours of my time, taking the unit down from the ceiling, remounting and aiming the new projector, long distance phone calls, and gasoline ($) to get to a UPS drop off spot. And will now have to do it all again... oh joy.

The little projector icon was wrong with the second projector also. Fast351, you might be right about the new firmware units have a "correct" projector icon.

Sending me an old firmware unit to replace an old firware unit is unforgivable on Optoma's part.

This unit was my third DLP projector since 1998 and my first Optoma.

Thanks for the headsup, Tim. Yes, Visual Apex is great but this is worrisome. I want to upgrade and am on the fence between the hd72 and the in76. Posts like yours are making me lean towards the 76.

Hey, Im not a handyman but my plan is to mount the hd72 on an RPA-u mount with 3 holes cuz I cant figure out how to get the fourth hole screwed in. The mount is centered pretty much and the arms are streching to the holes near the side. I'm going to measure the horizontal distance of the wall and put the screen in the center (not screwed in). Then using half of that distance, and according to the pj central website , mount the lens of the pj exactly 18'3" back. The cieling is some kind of stucco so I'm going to home depot in a few hours to ask for a thin piece of wood for the beams to hold up maybe 10 pounds and also to find out which screws go with the mount cuz it didnt come with the cieling screws. One person recomended plexy glass but I'm not sure how to drill the holes. Would be lower profile though. Am I doing this correctly? Should there be 4 holes screwed into the mount? Can I get some advice about screw sizes maybe or whatever I might not do correctly. I'm not even sure how to level this thing properly. Please help. Spencer

Oh yeah, Fast351 are you a Windsor or Cleveland? Great engines both...

Windsor engine :)

Spencer: I got mine hooked up with a 4 screw setup by flipping the L brackets at the end of the legs and using the 2nd size of screws included with the mount. Also used the washers.

Thank you Fast351, I'm going to do that right now. Looks like you have the same cieling material that I do. Did you follow the steps I just listed to center the lens? In addition, what size screws did you use on the beams? Looks like you removed the legs completly from the picture? Thank you for your time. You probably saved me some trouble already with leveling :)

Can anyone tell me the offset of the H72 vs the H31. I have the H31 and would like to upgrade, but only if I can pretty much swap the 2 out with much adjustment.

What I did is measure the center of the screen from the side wall, then measure the center of the lens from the side wall. I then measured the center of the lens to the center of the mount and subtracted that from the point on the side wall to get the lens centered side to side on the screen.

The little L brackets at the end of the legs are still there, they're just flipped around from the way they come from the factory. From the factory the L brackets have the adjust slots attached to the larger phillips screws that attach to the legs. I just flipped it so the adjust slot attaches to the projector, and the fixed holes attach to the legs. You'll see what I mean when you go to assemble it.

The ceiling above my projector goes into the attic of my house. When I was up there running the wires I screwed a 2x6 inbetween the roof trusses so I'd have something nice and solid to screw into. I then ran 4 2" lag bolts through the mount into that 2x6. (Yes it'd probably hold 200#, but it's never going to fail at that point :) )

With as little as this projector weighs, you could probably use sheetrock anchors (not that I would). Either that or screw the mount into a truss. The projector has enough zoom adjustment that you could probably line up on a truss and still get the exact picture size you want.

Hope that helps!

I believe the H31 has a 27% offset and the HD72 has a 32% offset IIRC.

Got my HD72i yesterday.

Compared to the MT-700 i had I must say it's much better looking and sleeker to have dangeling from the ceiling. It's a bit further back from the screen and quite a bit closer to the ceiling which is really nice.

Turning it on I noticed that the remote works flawlessly from all directions in my room. Pointed at the screen or from the screens position is no problem. The ceiling setting icon is correct so I guess I have the newer firmware, if the icon is a sure sign of the new firmware that is.

Picture wise the optics of the HD72i is really nowhere near the MT-700s. Colors were way of out of the box and I didn't have the time to calibrate it yesterday. As noted before the mounting holes are really weird placed considering the center of gravity and the really small M3 screws to compensate for it. Choose your mount carefully. My SMS Aero mount allowed me to have the center of the mount exactly above the center of gravity which to me feels better, considering the small screws, than the mount being centered above the lens.

I fed it with a 10m (no brand) DVI cable from my ATI 9700 card which worked just fine.

Anyone interested in my findings the next few days let me know and I'll post it.

I believe the H31 has a 27% offset and the HD72 has a 32% offset IIRC.


I have my h72 sitting where my H31 was. I think the H31 is actually 37% BICBW.

Either way the image shift gives you enough flexibility to get it right where you want it (about 3.5" up or down from 0 ) unless you are running 16:10 instead of 16:9.

I am interested in the H72. Can a Universal Ceiling mount be used for this model and any recommendations?

Thanks,

Bob

Pulled the trigger today. Should receive my 72 PJ tomorrow. Can't wait. No way is the kid playing with my new toy when it is set up. :p

I went with the HD72 as well.

My ceiling is about 7.5', so I had to flush mount it using an universal mount(mount goes inside between joist, built a custom support for it so projector lens is flush with ceiling). Projector is about 12 feet away from wall (room is 12x14), giving me about 105" screen. I used Screen Goo painted on drywall as screen.

Projector is currently connected to my Xbox 360 only. Since this is my first projector, and I am no expert in any way, I am completely blown away by the result. Watching some HD Trailers downloaded from Xbox Live justified every pennies I have invested in it. I now believe no 70 inch rear projection tv can match the effect that a projector creates. Playing some Fight Night Round 3 is like having real size boxers duking it out in front of you, and I won't even talk about the graphics.

I am very pleased with my purchase. I would recommend this projector to anyone looking to build a home theater or upgrade his. Also, I didn't notice any resets yet after 10 hours on the lamp.

I'll give you all the short version...

Purchased the HD72 on 03/10/2006 from an AVSforum sponser.
On 05/01/2006, I suffered my first firmware reset.
On 05/04/2006, I suffered my second firmware reset.
Went on vacation last week.
Called Optoma yesterday (05/15/2006) regarding issue. They had the cross-ship RMA processed by 3pm EST.
Today at 10am UPS rings my doorbell and delivers the new replacement HD72!!

How many companies can you name that would have a NEW replacement unit in your hands in less than 24hrs??? I cannot name not one! Also, just an FYI, I live in south NJ and the unit was shipped from CA.

Hows that for service... Optoma is truly playing at the top of their game!!!
:D :D :D :D :D

Can someone calculate this for me? If I tilt the ceiling mounted HD72 up such that the 16:9 image will move up 4 inches to fit my 90" diagonal screen, how much wider the top of the screen vs. the bottom? Let say the distance of the projector is 11 ft.

It’s the offset that prevents me from getting the HD72 and I am hoping that I can still fit it in my 7.5ft basement room. I don't really like the look of tilting the screen.

I am finishing my basement which is 24'x12.7' with 7'7" ceilings. I plan on purchasing the H72 soon. Can someone please advise the proper setup for this space. I will be ceiling mounting the projector and using the wall for the screen for now. I can easily run wire now before I sheetrock and put in the ceiling tiles.

I also plan on purchasing an upconverting dvd player and Direct TV HD receiver, and new audio receiver.

Thanks,

Bob

INDUSTRY PLANT!

Just kidding. I'm glad it's worked out for you. Perhaps they've changed some of their customer service procedures after some of us publically exposed their deficiencies here. I know they monitor this thread.

My old projector is finally on it's way back to them today. Hopefully they will be quick to credit my card.

I'll say it again. A field firmware update procedure would eliminate this problem. 5 minutes with a USB cable and a laptop and no more resets. But what do I know, I just design embedded controls.

-Mike

Anyone interested in my findings the next few days let me know and I'll post it.
I'm interested to know how it compares to the MT700.

Thanks.

Mike,

I totally agree with you on this point!!! Still though, their customer service is so far the best that I've delt with... maybe I just got really lucky.

TI has a propietary SW interface for upgrading this newer DDP3020 chipset according to guitarman's sources - although it sounds like they're working to get a smaller version of this available to end users. Infocus uses an older non-BC chipset which is how they got around this. None of the DDP3020 brilliant color projectors offer field upgradeable FW AFAIK.

I had great turnaround on my HD72. Customer support was responsive and helpful, and I because I hot swapped it was never without the projector for more than 24 hours. They picked it up door-to-door so it didn't cost me $1 in gas, and shipping was covered. They'll put a temporary charge on your credit card for the cost of the new one - a couple weeks you'll see the credit back.

I have had no resets or issues with the latest FW at all now and I'm well over 100 hours with it now. This early FW issue should be coming to a close except for the dealers who still have older inventory.

My problem with shipping the "firmware needing units" back to Optoma is that UPS only comes to the house to pick the unit up DURING THE DAY, but no one is home to answer the door because everyone is at work. UPS will call on your house three times for a package and then thats all folks.

So the first return of my HD-72, I went to a UPS ship point ,and paid for the shipment back myself. For the return of the second HD-72, I have had to take off from work to be here today at home when UPS shows up. They just showed up at 3:00 PM. A day of vacation pay used up.

And this second time won't be the hot swap deal. I am helping my middle son buy his first house and I didn't want them to charge my charge card a second time in the same billing period for $2000, for which interest will be charged, and also show up as a large debt on my credit report.

So can you can see my frustration in having to jump through hoops FOR Optoma because Optoma couldn't "do it right" firmware wise, on the first and even the second HD-72 units I received?

I asked for compensation from Optoma in the form of a free spare bulb, a bulb that about every Optoma vendor is now giving out for free with the new HD-72 units, but the Optoma manager said "no way."

Okay, so the score is: time to mount, aim, calibrate, take down, package, gas to get to UPS, ship, then...

Do it all over again only this time having to use a day of vacation and take off from work...

And then the THIRD HD-72 shows up and I have to mount, aim, and calibrate for the third time.

So here I sit for a week without a $2000 projector I bought in good faith, waiting for the THIRD HD-72 to be shipped, probably next Monday, to be received probably next Wednesday or Thursday.

I requested that Optoma verify the new firmware, prior to shipping the next unit. Am I being unreasonable?

Tim, I would return it. Get a refund. Then re-order a new one and you will get the Free bulb.

You have every right to do this after being sent 2 defective units and taking your time out and having to pay for shipping.

:) d

Actually, to be correct about it. Optoma reimbursed me for the shipping... but STILL!

Thanks Dave. The original vendor, Visual Apex, was great and this firmware mess wasn't their fault.

So I don't really want to pawn this Optoma problem off on Visual Apex to resolve.

Although there is no firmware indicator in the menu near as I can tell, there is a way to tell which firmware you have:

There are only two firmware versions for this projector, according to Optoma.

V1, which has the reset problem
V2, which does not.

The way you can tell is by looking at the projection style icon in the menu. If you change the projection style to ceiling mount, and the icon in the menu still shows the front projection floor mount icon, you have V1. If it correctly shows the ceiling mount icon, you have V2.

Hope that helps.

-Mike

Would you please post a picture of this screen you are refering to? i m trying to figure out which firmware i have. would a serial number be any help?

i have the projector set up & in the projector menu - i see 4 icons on the bottom for the screen for choices of position.

so far, out of the box with no calibration - the picture is pretty decent. bright & vivid. i currently have HDMI connected to the OPPO player. the gefen 4x2 hdmi switcher works flawlessly between the HTPC nvidia 6600gt pci-e & OPPO.

i was suprise on the throw distance. 106" screen with a 15' 9" throw which is pefect for my 10' x 23' x 8' room & all the cables i have brought in the last 6 months from monoprice.com

In my case, the proper "mounting icon" was chosen as a front projection, ceiling mount setting. However, after chosing this mounting option and immediately after pressing return, the mounting icon that is indicated is the "wrong icon" for the "mounting setting" that you just input, not the one proper for a ceiling mount, front projection. I noticed this right off the bat. But the "proper setting" is held (at least for a while), even though the wrong icon is indicated in the menu. Fast 351 says that this is the clue that you have the bad firmware

But then you will eventually lose all of the settings, if you have the initial defective firmware. It is obvious, as when you turn the unit on, the Optoma logo would be upside down in my ceiling mount example, having all been reset to factory original settings. The settings could hold for several days or even a week or two, and then all is lost

I hear ya, Tim. Visual Apex are great. Thats where I got my h57 from.
You should definitely get the free lamp though after this.
I am looking to upgrade. Its down to the hd72 or the in76.

I just received my H72. I'm at work though so I havent even had a chance to try it out. After hearing your horror story, I'm wondering what I should do if I see the wrong icon when I set it up. I'm very tempted to box it up and send it back for a full refund rather than play the crosship game with Optoma at $2000.00 a pop on my C.C.

Also when I received my projector the Fragile tape that seals the box was cracked all the way across and there was a new piece of tape over the area at the center where the flap goes into the box. I know the fragile tape could have split by the FedEx guy carrying it by the side of the box instead of the built in handle. :rolleyes: . What I cant explain though is the new piece of tape that was applied over the center portion of the box.

Best explanation I can come up with is if the people at Optoma broke open the boxes to do firmware upgrades and then just used this piece of tape to quick reseal the box.

I cant wait to get home to try this thing. I'll report back if I have the new firmware or not.

Your story is exactly why I'm still holding off on pulling the trigger on this projector. I'm a consultant, and when I don't work I can't bill, and when I can't bill I don't make money. So that whole being there for UPS to pick up the package isn't going to fly. Secondly, while I have excellent credit, I do not carry any credit cards. I have a bank Visa check card, but I'm not going to let them take $2000 out of my checking account for however long they wish while they cross ship. I was hoping to have my projector up and installed before next weekend, but I'm still waiting...

Question no one has asked: what happens to the used HD-72 that are returned to Optoma? They cannot be sold as new units, as they are not new. The various states consumer protection/consumer fraud agencies would be all over them if they did. Maybe. Like they are all over the "no Juan left behind" bills being rammed through Congress.

Does anyone know of any vendor selling a crap load of "open box" HD-72 projectors? If not, what could be the reason? Shudder to think... who knows, my third HD-72 may have an actual 1237 hours on a continually resetting bulb hour counter that now reads ZERO!

I worried about the same thing becaus the Optoma cs ppl seemed shady about the whole money lost on the firmware deal, but Proj People and reputable sellers probably wont do that. Look on Pricegrabber and check out the reviews for the companies or some other source if youre worried.

UPDATE: The DVI-D port on the PJ does not work from DVI to DVI. I just recieved a 30' Blue Jeans HDMI-DVI cable and it works flawlessly. I measured the distance to an exact 18' 3" from the center of the wall and the horizontal distance as well on the cieling. Still cant figure out what screws I need for the mount or even how to put the RPA-U in beams. There arent any instructions for the ceiling.

The beams are horizontal and 3" away from the spot where the lens should be so I'm going in to Home Depot to get a board and spraypaint it white. The last measurement is holding the PJ where the mark is for the lens and tracing chalk around the mount to make sure I get the right spot. Maybe I should get a piece that streches to the beam behind it (about 20") to make sure its secure but It might look weird. Not sure how to proceed. Any thoughts on sizes of wood/ plexyglass or ideas that might help me? Spencer

Any chance you can get to the top of the sheetrock to slide a piece of plywood up there?

Barring that, you could probably use four of those corkscrew type sheetrock anchors. They hold 50# each on vertical walls, they can probably hold 2# on a horizontal surface.

They are either refurbishing them and selling them as such, or they're using them as replacement units. I haven't seen any refurbished units anywhere yet, so I'd assume the latter.

That's always the risk with a brand new product. If my notes are correct the HD72 has been shipping for about 11 or maybe 12 weeks...

Remember everyone - we're talking firmware issues here, - basically software - anyone own a piece of software for their computer that is version 1.0? .... nope its all 1.03.2 etc. fix after fix after fix.

We tend more and more to demand perfection, but market forces just won't allow that, the company that tests its product to death so that it is 100% perfect, will probably start shipping it shortly before their competitors discontinue the competing mode, and have the next generation (with flaws) coming out.

The hope is that products like HT projectors -with their 12-15 month life as a current product (less if late to the market), have no serious flaws, and obviously a reset issue, isn't a good problem to have.

As someone else noted, the field upgrade issue looks to be a limitation imposed (or not yet available) by TI, and that everyone using that chipset is in the same boat. Of course there's always the more expensive IN76 with the older technology... but then, bye bye to Brilliant Color - which really is a nice touch! -art

Too soon, since Optoma, like the rest of the world offers a Limited warranty not an Unconditional one, they are not obligated to replace with a new projector (no, I'm not a lawyer, but I had been selling audio and video for 30 years). I know of no company's replacement program either (for expensive things, not $30 items) that promises new.

So its very likely that Optoma, if replacing (as opposed to fixing) units sent in with the old firmware, will use refurbished units - the others sent in ahead. Otherwise, they would do the usual upgrade when a customer's comes back, but that means more delays, and customers would scream louder if it took Optoma 2 weeks to return their unit with the firmware upgrade.

Don't worry though, there will always be refurbs, but not until they have a mountain of them. Most projector companies prefer to get a pile of them and offer to just one or two dealers (or distributors). So don't count on seeing any HD72 refurbs probably till near yearend. -a

Actually, to be correct about it. Optoma reimbursed me for the shipping... but STILL!

Thanks Dave. The original vendor, Visual Apex, was great and this firmware mess wasn't their fault.

So I don't really want to pawn this Optoma problem off on Visual Apex to resolve.

Gotta disagree, the reason for buying from a "great" vendor like VA, is that they are a direct dealer that buys volume, (I presume the "great" you are talking about means you liked their recommendations and help and they have you a good price and shipped stuff when promised). Dealers are your first line of defense.

Direct dealers are worth the extra they usually charge compared to those that buy from distributors - because they have influence and contacts with the manufacturers.

VA and other major AV directs routinely (ok maybe not routinely, but occasionally for sure), pick up the phone and call manufacturers like Optoma, etc., and say - HEY, I've got an unhappy customer here, and I need an exception this guy should get a new unit, or whatever.

And in many cases the Dealer will get you your wish, whereas you, as consumer cannot.

If you think your dealer is too great to get involved, then you are forgetting that the number one measure of greatness is customer service. If you don't go to them, you haven't even made YOUR best effort.

You might have been pleasantly surprised. (I spent enough years as the owner of an online projector dealer to know this.) We constantly argued, fought, and begged vendors for special situations, favors, etc., and quite often we got what we asked for - it was always a strain on our customer service people, but it kept the customers happy, and generated referrals.

It's the dealer's making the effort on your behalf (whether successful or not) that really determines if they are great - anyone can recommend a product, and anyone can give you a good price, and ship on time. (at least anyone who can do all three qualifies as a fair to good dealer). -a

I'm interested to know how it compares to the MT700.

Thanks.

This may help, if you visit my site, I did a comparison review of the BenQ PE7700 (which is all but cosmetically identical to the MT700) with the HD72, Panny 900u, and Z4. This was about 2 months ago, shortly after reviewing the HD72. I had both the BenQ and HD72 in house.

Each of the four, of course, has some strengths and weaknesses compared to the others. And read between the lines. (there are limits as to how much I can piss off the manufacturers that send me projectors to review). -art

I'll probably get shot for providing the link, but:
http://www.projectorreviews.com/HomeTheaterReviews/HTprojectorComparison_under2000.asp

BTW pricing dynamics have changed since that article was written. And it seems from the BenQ thread that the fix for th lamp blowing does work, at least I haven't seen anyone complain about lamp failures on the units shipped since mid-January.

Well I just got my HD72 setup. I set it to ceiling front projection and the icon was correct in the menus. So hopefully this means I have the new firmware.

Fast351 Thank you for all of your help and time presenting different options. There's no way to put a piece of plywood down in the cieling but what I thought of it to get a piece of wood about 21" long bc I believe the beams should be about 18" apart and make it an oval shape after spray painting it. It would cut down on the shaking if someone is walking around upstairs and make it more level considering that the sheetrock anchors are more designed to be perpendicular. Ill post some pics of the finished product if anyone is interested and if I ever figure out how to screw the mounting top part into the ceiling while the PJ is attached. (There arent any instructions but maybe home depot will help) Again thanks to Fast351 and M4tt. Spencer

UPDATE: The DVI-D port on the PJ does not work from DVI to DVI. I just recieved a 30' Blue Jeans HDMI-DVI cable and it works flawlessly. I measured the distance to an exact 18' 3" from the center of the wall and the horizontal distance as well on the cieling. Still cant figure out what screws I need for the mount or even how to put the RPA-U in beams. There arent any instructions for the ceiling.
Spencer

OK, just tried hooking up my LG 7832 Upconverting DVD player to the HD72 via the DVI-D connection and the PJ didn't see the signal & the player locks up. I hooked the player to my computer monitor using this connection & it worked fine. The component connection is recognised. Don't have DVI to HDMI cable yet. This could be a problem with the LG...known DVI issues. Yet to try hooking up my Mac Mini thru DVI. Anyone else had this?
Bud

PS...so far LOVE the picture,even thru component!

I just received my projector today and the picture looks great barring two very noticeable vertical lines on the ride side of the picture. It's not my screen (tried a blank wall too and they are still present). Anyone have any suggestions or does this unit need to go back?

lendl1, have you considered it might be the source? Try a different source and see if that clears it up. Many displays have overscan which would explain why you never would have seen it before.

Try the digital zoom or overscan functions on the HD72 to get rid of the garbage lines on the edges of your source. I saw this on my HD-Tivo signal and had to do this to eliminate those lines.

Mike

Right, I have a green line on the right and a purple line along the bottom through my HD cable box. I just use the screen border to hide it.

Anybody watch CSI last night on their HD72? I couldn't get over how good the picture was, the color and depth were amazing (bc4, tru 1). It turns out the HD72 does a better job scaling than my HDTV box. Lost always looks great but I'm surprised that Alias hasn't been as good as it's slightly grainy at times. Still good but not the sharpness of Lost and CSI.

If vertical signal shift (different from image shift) or overscan which on the HD72 actually crops out pixels doesn't work. Then use the TV video choice, it has the most overscan at about 5%.

Hey Rod, grooving on HDTV? :) HDTV on the H31 looks nice, but nothing like looking at it on a 720P machine, right? Plus a powerhouse brightness projector with brilliant color. Speaking of colors Lost comes to mind, which is why I posted lost screenshots in the reveiw thread, which got buried by the way :(
Enjoy

Tom, I'm addicted to HDTV. 720 at my seating distance is the bomb. The H31 you tuned is great but doesn't have the detail of 720 for sure.

LOST is extremely good for color and I like BC3 for a little more natural pic as LOST is full of color and is very impressive anyway. I'm still beside myself after watching CSI on sRBG, PC,BC4 and letting the PJ scale instead of the Moto box (tested back and forth last night). I've never seen the depth before that I was getting last night on CSI.

Oh, by the way. Good tip on bouncing the remote signal off the ceiling. My 72 is table mounted and it is hit or miss bouncing off the screen but off the ceiling is 100%. Easier to see what buttons I'm trying to hit too. :-)

It's the little white remote, I have to do the same thing with the HD7100/same remote.

Does the 1280x768 res. mean i could watch standard cable (4:3) natively, and HDTV natively too ???

Ive been dreaming about the H78DC3 for awhile now and even though contrast and shadow detail are the most important things to me, the HD72 price is starting to pull me in :D

Ghost, they're gathering in the Park :)

1280X768 native is best for computers. For TV you'll still get bars on the sides. Most will setup a 720p screen. 1280X768 is taller than a basic widescreen, a electric 4.3 screen could work, but still with TV they'll be bars on 4.3

Has the whole issue with the settings resetting been resolved? If I order a unit from Visual Apex today might I be subject to this issue?

This is really making me consider buying another unit.

I ordered from Projector People this week. I received a unit with the new firmware.

I'm basing this off of someone saying that if your Rear Ceiling Projection icon displays properly in the menus than you have the newest version.

I dont have enough time on my projector though to definitely tell you I'm not gonna have the reset issue.

Hope this Helps.

Call Optoma and ask them "Starting with what serial numbers does the HD72
have the latest firm ware upgrades?"
Then call your dealer and make sure they send you a projector that has a serial
number higher then the ones Optoma quoted you.

I got my first reset today (About 25h of use). Didn't annoy me much, but it raised another problem it seems. Ever since that reset, I hear a high pitched noise which I never heard before. Obviously it doesn't come from the fan, so I suspect color wheel or lamp. If it is the color wheel, then why it was not making the noise before? Could the reset damage the lamp? It never goes away now no matter how long I use it.

When you return the projector, do they always send you a new one?

Thanks

Vood,

Would you mind checking if your projection icon is displayed correctly in the menus? Also when did you purchase your PJ.

Thanks.

It never goes away now no matter how long I use it.

When you return the projector, do they always send you a new one?

Thanks

what do you mean by "resest" ? what was the "reset" symptom? if you had it ceiling mount, did the projection mounting icon menu style rotate back to as if it was table mount? or did the projection image rotate 180* degree?

This statement has me worried about getting the HD72.

"The use of this projector and a 92-inch diagonal screen should not be a problem in rooms that have standard ceiling heights of 8-feet when the projector is mounted on the ceiling. Using this projector in rooms with standard ceiling heights of 8-feet and 106-inch screens may be a problem due to the offset."

I was planning to upgrade to a 106 screen but I have 8' foot ceilings.....anyone have this setup and can say that it works without any issues?

Thanks,

Well you only have 96" to work with, so.

Floor to Ceiling=96"

Offset of around 35%=18"
Flush mounted projector=6"
Screen Height 106" Diagnal=52"

So the top of your screen would have to be about 24" from your ceiling. This would place the bottom of your screen about 20" off the floor.

Vood,

Would you mind checking if your projection icon is displayed correctly in the menus? Also when did you purchase your PJ.

Thanks.

The projection icon is not displayed properly, so I assume it is the defective firmware (got the settings reset). The projector was bought in march, but I had to build the room beforehand, so I installed it just recently.

Also, It was talked before about the projector not shutting down. It happened to me once, where the lamp did go off, but the fans did not accelerate and were continuously running. Had to use the on/off switch to bring it back online.

What's worry me the most is not the firmware issue (I will return it), it's that noise coming out of the projector. How many owners of HD72 has this? Will all units make that noise or it is just another defect?

Thanks

I have a 106" setup, and 8' ceilings, and it works fine. Yes, you have to tip the projector back slightly, but there is no visible optical keystoning, and even if there was, it'd drop into the black border on the screen.

The top of my screen is about 18" from the ceiling, so around 13" of offset, and it works fine.

Not to mention the fact you also have a digital offset of a couple inches available for a 720P source, AND, you could always tilt the top of the screen towards you as you tilt the PJ towards the ceiling.

The offset "issue" seems to be overrated. Heck, I plan to use a 100" screen with a 7' 4" room height. I'd be more worried about the firmware issues.

Pardon me for not wanting to read this 64 page thread (or 100+ pages that result from searching) ...

How is light leakage on this projector?

I like the price of the HD72 and free lamp to boot now. Looks like the HD7100 has better CR - 5000 on/off vs 3500 on/off. Has anyone compared these units and how much better is the Samsung SP-H710AE?

Pardon me for not wanting to read this 64 page thread (or 100+ pages that result from searching) ...

How is light leakage on this projector?

Very minor - basically its not an issue.

Since I've been researching which projector to buy I'll save you a lot of time and reasearch.

The only reason not to buy this projector is if it won't fit your room/screen due to the offset or if you must have perfect color calibration out of the box.

This is THE 720P projector to buy for the $$$ it can't be beat.

Yeah I tend to agree MUCHO ... I really want a DC3 machine, but the only one that's still in production that works for me is the BenQ8720 (the HD7100 is way to short of a throw)

Thanks for the answer ... and the tip ... I will likely be ordering next week.

Thanks for answering that for me. I dont really hear any out of the ordinary sounds coming from my PJ. It does have a slight high pitch sound to it but it has always been there. Maybe you didnt notice it before and you were just paying closer attention because of the reset malfunction.

Either way if you crosship they send you a whole different projector so you wont have to worry about the one you have right now. When you get it I would be interested in knowing if it also has this sound youre hearing.

Sorry you're having to go through the swap thing I hope Optoma takes good care of you.

How far do you have your projector from the screen?

Just bit the bullet on a HD72. Got a great price, free lamp, and a extra year warranty. HT wont be ready for a couple of weeks but it is exciting!!!

I just received my HD72. Can anyone tell me what the difference is between the image shift in the HD72 display menu and the horizontal and vertical position shift in the setup/signal menu? Are there any pros/cons to using either of these?

Thanks for any advice.

Regards,

Dennis

Trying to decide what screen to get with this PJ. I currently have a 92" GW with my H31.

I am building a new multi-purpsose HT room where the light will be more controllled than when I had the H31( dark walls, windows blacked out etc.

I have been looking at getting the 106" greywlf II or maybe the greywolf 1. BUt I am wondering If I even really need a grey screen now or should I get a White screen? Will I get a better picture with better colors on the White screen vs the Grey?

Can anyone recommend some good screens for approx the 300.00 range.

I believe the one in the display menu is the one you would normally use to move the picture up 24 pixels or down 24 pixels if you are using 16:9.

The position items under the setup/signal part of the menu I think only apply if you are using a PC. These options dont even show up in my menu when I'm just connected to a DVD player over HDMI.

Hope this helps.

Thanks for your help! The image shift in the signal menu shows up when using the component inputs.

I just installed my HD72. Love the picture, pretty darn happy over all.

However, there is a big delay between the audio and the video. My processor has a lip sync delay that goes to 200ms and even at 200ms there is some video delay.

I am using an Oppo DVD player and the HDMI input on the HD72 (through a DVI to HDMI converter). The video is too slow so you can always notice the lip sync problem.

Either I'm missing something (who, me?) or this is a significant issue that many of you who own HD72's should be experiencing as well.

Any thoughts would be great.
Thanks.

(1st post, btw, so hello to you all and thanks for all the good advice I've obtained by reading this site)

It's yer Oppo. My Oppo is set at 8 for the audio delay in the setup menu. You will probably have to try different settings till you get it spot on. It also depends on which FW you have installed in the Oppo. When I installed new FW I had to reset the audio delay.

Just an fyi, the audio delay on the Oppo is only active on the analog audio outputs, not the digital audio outputs.

That sucks! Nobody mentioned this analog audio delay thing...now that the HD72 and OPPO are shipping to me! How am I going to enjoy dolby digital with OPPO and HD72?

Kin-ng I believe you misunderstood the response.

I could be wrong though...I know many people use the Oppo and HD72 and they swear buy it.

That sucks! Nobody mentioned this analog audio delay thing...now that the HD72 and OPPO are shipping to me! How am I going to enjoy dolby digital with OPPO and HD72?

Easily - you just wont be able to delay the sound. It is indeed rare when you would want to delay the sound - most likely it would only happen if you're watching a Xvid file that has been converted incorrectly.

For 99.9% of your DVD enjoyment this will be a non issue.

Does anyone know if you can tell by Model Numbers if the HD72 has the latest version of the firmware....my supplier has one that I am going to buy but would like to know it has the latest firmware first.

keeep cool my man!!!!

i have no problem with the synch using oppo & hd72.

keep cool!!!

my concern right now is to understand what everyone means when they refer the hd72 "RESETS".

i know for sure now i have V1 firmware. i just want something concrete reason when i call optoma next week or so.

any suggestion?

Thanks guys! Looking forward to tomorrow nite. Really didn't want to post anything until receiving them first. Oh well.

The oppo audio delay is indeed on the digital audio outs as well. And in my experience, like 1 in 30 dvds need it.

This has been well covered in the OPPO FAQ. The audio delay is only active on the analog outputs. You can adjust the delay with a digital audio output, but it has no effect.

What screens are you guys using with your HD72 . I am escially interested in ceiling mounted setups. I was all set to get the Da-Lite Hi Power but I have been reading that they are not the best for ceiling mounted setups because you viewing falls outside of the viewing cone.

My ceiling is about 8' which seems to be the point where the HiPower becomes not as great.

Anyone have any recommendations for a screen to replace the Da-Lite HiPower around the price range as well.

Thanks,

tones

The sky's the limit for screen types. You can go gray, matte white or gain with the HD72 birghtness depending on the size of your screen.

If you want a manufactured fixed screen I'd look no further than Carada with Brilliant White material. It has a very wide viewing angle even with the 1.4 gain with a smooth surface (no texture or glass beads). Their service is top notch and it's very well built. They're a forum sponsor so you can find their link above.

Will this PJ actually take vga from a pc using a simple vga-DVI adaptor into the DVI port? It seems a little unclear to me. The manual does say that the DVI port will take RGB but to the best of my knowledge RGB and vga are different animals. Can someone please enlighten me before I head out and buy the leads?

This has been well covered in the OPPO FAQ. The audio delay is only active on the analog outputs. You can adjust the delay with a digital audio output, but it has no effect.

It actually works on digital out also, as long as it's just 2-channel PCM output. If you're doing DD or DTS, it doesn't function.

I was watching a concert DVD the other day that had only 2-channel PCM, and the delay had an obvious effect.

The other controls regarding sound have the same limitations -- the flat and sharp keys, etc. These work on 2-channel PCM.

Most definitely works. I bought a standard VGA to DVI cable at Fry's, and it works perfectly on my HD72 with my Dell laptop.

I spent over $500 and over a year to get all the equipment (such as a compressor and HVLP gun) to paint my DIY screen and in the end, spent another $500 to get the Firehawk fabric and made my semi-DIY screen. I should have spent $700 to get a bigger fabric instead of my current 90" screen. Anyway it's best to get lots of samples and see which one you like best and give Jason a call to get the fabric.

Ok, I got my HD72 and Oppo and I must say I am a little disappointed. HD72's HD performance is much better than my X1, but Oppo's 720p is quite disappointing. I found myself constantly adjusting the focus and sharpness of the HD72 and Oppo. I switched the Oppo to either Digital input and it's all the same. Can you guys post some settings on the Oppo or HD72 that you are happy with? Or can somebody attest that the Oppo's 720p to HD72 is sharper than a (cheap player, in my case, a Pioneer's) 480p output to a lower resolution projector such as my X1? Or in 720 resolution, the DVD is always less sharp than my X1?

To really compare the 2 instead of just based on memory, I played the same DVD on 2 different setups to the same screen and shielding the lens back and forth and see which one is sharper. Based on my eyes, the HD72/OPPO combination is not much sharper, if any at all than the X1/Pioneer combination. However, the contrast of the HD72/OPPO is much much better but this should be mostly attributing to the HD72. So I don't really know how people can say OPPO being close to the HD quality...and I've experienced audio-sync problem already. Yes the firmware is the latest non-beta one already. Now I know why people wanted to buy the HD-DVD players.

I'm not sure about the horizontal and vertical position shift, but I suspect it will remap the data. On many projectors with analog PC input you might find that your computer screen is several rows and or columns off, so that you might be missing the first 3 or 5 or whatever columns from the computer signal. So you wouldn't see the first few columns when projected. Much like a CRT set so the left side is off the screen and the right side is too far to the left. But, just guessing.

The image shift feature, as I recall, lets you move an image up or down. This could be handy with a DVD with letterboxing. You could choose to move the whole movie image downward so that it would at the bottom of your screen instead of about 10% above, it would, therefore put all of the letterboxing at the top.

And if you had a screen pulldown or motorized, alternately you could choose to not bring the screen down all the way (by the full amount of the top and bottom letter box so it is the shape of the usable content itself (2.35:1) so that you have no letterboxing at all. IN that case you would be using the image shift to move the top of the viewable image up to the top of the screen, and the bottom would be where the bottom is, with the rest of your screen surface still tucked away inside the housing.

Of course with a full 16:9 image ie an HDTV signal, you would have to go back, and lower the screen fully, and readjust the image shift back to normal, or, if you lef the image shift as described in the paragraph above, part of the image would be hitting the housing and above.

I think that's about right.

To really compare the 2 instead of just based on memory, I played the same DVD on 2 different setups to the same screen and shielding the lens back and forth and see which one is sharper.

Now I know why people wanted to buy the HD-DVD players.

Ultimately, you should pick up some extra sharpness of the HD72, but it still comes back down to the source material is 854x480, so has to rescaled to the X1 (down slightly), or up to 720p. Either way you don't have 1:1 pixel mapping so there is aliasing, scaling... whatever combinations of technology, to make it work, then it's how well its done. Neither resolution (X1 or HD72) should theoretcially be as good as an 480p projector with a standard DVD. But the HD72 and other 720p projectors have smaller pixel structures so tend to appear smoother.

Ideally you want a true 720p signal, not even a true 1080i source to get the sharpest image out of a 720p projector. Down scaling a 1080i to 720 for example sometimes has to split 3 pixels of info, into two. imagine you have three pixels in a row of 1080 data, and the pixels are white black white. With 720 resolution you have to figure out how to project that in two pixels - you can't just drop one, instead you end up with affecting adjacent pixels as well to try to reproduce the white black white. Thus the big fuss on who has the best software - Faroudja, Pixelworks, etc.

Want to see the the HD72 shine, feed it a higher resolution image. I think some HD channels are broadcast in 720p (ESPN-HD?). I would think, in that case, if you set the cable/satellite box to send 720p you should get a razor sharp image. But, even 1080i looks really great. Hi Def DVDs? So much better than conventional on a 720p machine. Even lower resolution projectors will improve, but the 720p's should really shine.

I use the Oppo, and am pleased with the picture quality. (I hadn't noticed the audio issue, but I didn't have the HD72 that long. I do think it's better than several previous DVD players I've owned and the scaler seems to be particularly good, better than what is found in some projectors.

With some projectors their internal image processing might be better than the Oppo's and you might want to output 480i, and let the projector do all the work. With others, the Oppo's results are better than the projector's.

Hopefully we'll all eventually end up with 1080p projectors and all 1080 source material. Now that will be sharp!

Put the sharpness on the Oppo to low or higher.

I've run both the HD72 and the H31 at the same time thru DVI. The H31 is slightly sharper than the upscaled to the HD72. I run the oppo video settings at zero. It yields a great result on the H31. The upscale to the 72 is slightly softer but after messing with it I started running the sharpness on the 72 at zero also (I did have it at 7 and anywhere between -10,+15 testing it). It is a softer picture, but for my seating distance I don't see SDE now, which really bugged me on the H31. If you have ABC watch HD content there as it is 720P. That is where you really see what the 72 can do. Some HD video quality is not as good as others. LOST has been extremely good. The scaler in the HD72 seems to be very good too because I watch NBC at 1080 and let the 72 scale it. My moto HDTV box does not do as good a job as the 72 although it's still acceptable.

I did watch Desperado thru On Demand HD last night. On Demand sometimes has glitches so you get a jerky picture at times. Since I have the DVD I fired it up in the Oppo and ran them both for comparison. The transfer on the DVD must be awefully good as it darn near matched the HD On Demand version. I have to say I was pleased with either in terms of sharpness. Maybe On Demand HD isn't that great of a source and I really don't know (as I don't watch it much) but they both looked very very good. Or maybe that was just Selma.

I wanted to ask one of you guys if going from a 106 screen to a 120 screen would lower any detail or resolution.The throw back on a 120 screen is 16.2ft without zoom which I would not not be able to do.The maximum throw back would be 13.6 ft,I would be able to go as back as 14.6

Can you give me a quick run down on pro's vs con's on the HD72 vs the HD7100

I know that you have seen both of them. Light output is a concern to me also.

Thanks

The HD72 is allot brighter. The HD7100 has an extremely dark black level and very high contrast. 2000.1 on the HD72 and 4400.1 on the HD7100 both tuned down to D65k. The Optics are of extreme high quality on the HD7100 also. It's shows in the images high detail, also 1.1 pixel match is so clear the SD is more visible. The price you pay for high detail in the image I guess. Is all that worth double the money I don't know, it's a how much TV / good TV do I need. :)

Hey guys,

I think I am ready to take the plunge on the HD72, however I am worried a little about rainbows. I have contacts and when it is dark when I look at lights I see halos around them sometimes colored (mini rainbows). I have never viewed a DLP projector for more than a few minutes (I did not notice them then, but had never even heard of them then) so I am a little worried I may see the dreaded rainbows when wearing my contacts. Can anybody who sees the rainbows comment on whether they have similar experience with lights at night?

Secondly, what cables will I need to purchase with my projector? If the HD72 does not work for me because of rainbows I think I will try the Panny 900.

My HD 72 has about 330 hours on the lamp, and it seems to be dropping light output very rapidly. Need to boost brightness almost every night. Anyone else experienceing this?

I just got a new HD-72 after sending my 30 day old projector back to Optoma
for the same problem you have. In low fan speed mode my original projector
would produce a noxious stink like burning plastic and the lamp was aging to fast.

I have found a work around for this problem in case you cant return your
projector for exchange. Run your projector in the High Altitude fan mode.
This will help keep the lamp a lot cooler and there is no burning plastic smell.
I run my new projector this way and so far, no loss of lamp life and no stink.

I picked up the Sanyo Z2 a long while back, but others of you might be interested in the HD72 mem day savings. Projectorbundels has a great deal going on.

I would like to check out a HD 72 but can not find any stores that has it, any ideas for the metro Detroit area, Optoma's Web Site was no help, all it did was list stores like Best Buy and Staples and they don't carry it.

Sorry, weird rule though...

Hi.

After calibrating my HD72 I can clearly see the red is the limiting color, and have thought of trying a mild red filter.
But I have never used a filter before, so I have a few questions.

1. If I use a red filter (cc10r) can I get increased light output by increasing blue and green ?
2. Where can I get cheap filters to use for this ?

I just got a new HD-72 after sending my 30 day old projector back to Optoma
for the same problem you have. In low fan speed mode my original projector
would produce a noxious stink like burning plastic and the lamp was aging to fast.




Mine doesn't produce any odor, nor does the lamp seem to be overheating.

Mine doesn't produce any odor, nor does the lamp seem to be overheating.

Try the High Altitude fan setting for a few days and see if the aging of your lamp
slows down. A cooler lamp should last longer. If nothing changes, contact Optoma
Technical Service. They were very helpful to me once I explained my problem.

I would send your unit back Audiomod. It sounds defective. Most HD72's run very cool and quiet in low or high lamp mode. High altitude mode however is down right loud and obnoxious (vacuum anyone!). A burning plastic smell is an indicator that something is just not right - unless of course you are at 5000+ ft. in altitude.

I've had mine for 170+ hours and very little to no loss of brightness in low lamp/fan mode (I'm sure it has but I'd need a tool to measure it because it's so imperceptible).

Mike

I'll just add another voice as my 72 runs cool and there isn't any plastic smell. About 60 hours on the bulb so far. I'm surprised at how much cooler it runs than the 31.

Hey Mike,

Are you running contrast of 50? I can see all the steps and run Bright at 0 and contrast at 50, BC 3. I thought I wouldn't be able to see all the pleats on a tuxedo shirt but it's all there.

Hi Rod,

No, contrast setting for me above 5 starts blowing out white detail. I have a Carada brilliant white screen though. You have a gray screen correct? Optoma Graywolf IIRC. That is probably the difference. I recall guitarman had similar high contrast settings for his graywolf and the HD72.

I run brilliant color at 3 for movies for color accuracy, 8 or 9 for PC or some HDTV sports, and it doesn't blow out white detail. It gets much brighter too. Most likely using more of the small clear segment in the color wheel for the higher lumens at the high BC setting. I always run at low lamp mode - even when using my full 120" 2.35 screen with anamorphic lens. Very nice.

Still debating on the ISF cal via guitarman or something like Spyder2Pro. I know the filter sensor isn't as nice as Tom's, but I could get close and use it on other monitors in my home as well...tough call.

Mike

My first HD-72 had the burning plastic smell. It was returned to Optoma for the firmware upgrade anyway, for constantly losing its "memorized" settings.

The second HD-72 sent to me by Optoma did not have the burning plastic smell, but in addition to also having the defective firmware and losing its settings, the DVI input would occasionally be lost and the unit would search for an active input. That was not a problem with the first unit, using exactly the same high quality cables for the second unit. The lower left quadrant was also not quite as sharp as the rest of the screen, when focused.

The third HD-72 seems to have the right firmware, no burning plastic smell, focuses well, and all inputs "stick." I guess that the third time was the charm. Better be, or I will slit my wrists. Missed the free bulb offer at Visual Apex by a few weeks. Finally got a working unit last week, eight weeks after I originally purchased the first HD-72.

No more early adopter stuff for me...

I would send your unit back Audiomod. It sounds defective. Most HD72's run very cool and quiet in low or high lamp mode. High altitude mode however is down right loud and obnoxious (vacuum anyone!). A burning plastic smell is an indicator that something is just not right - unless of course you are at 5000+ ft. in altitude.

I've had mine for 170+ hours and very little to no loss of brightness in low lamp/fan mode (I'm sure it has but I'd need a tool to measure it because it's so imperceptible).

Mike

I did send it back. Optoma sent me a new projector. My point is simply this, if you
have the same problem my original HD-72 had (which is a plastic stink and a huge
loss of lamp brightness over a short period of time) then contact Optoma and
have it fixed or put the projector in the High Altitude fan mode.

Note: I did try the higher fan speed on the old projector and the stink went
away and the lamp did not lose any additional brightness.

A question to all HD72 owners. How does your projector look when using the S Video &
the single RCA video input? I tried mine with a Sony Laser Disk player and JVC SVHS
tape deck and the picture is crap. The picture looks very noisy. All other inputs are clean
and clear. Note: Even on my old Infocus 4805 these inputs did not look that good, so
this my be simply due to the low resolution nature of these sources.

Hi Rod,

You have a gray screen correct? Optoma Graywolf IIRC. That is probably the difference. I recall guitarman had similar high contrast settings for his graywolf and the HD72.


Still debating on the ISF cal via guitarman or something like Spyder2Pro. I know the filter sensor isn't as nice as Tom's, but I could get close and use it on other monitors in my home as well...tough call.

Mike

Right, I've got the graywolf and since my wife is determined to turn lights on all the time it's a good thing!

I took my DVE disk around the house and did all the tv's and was amazed at how much better the pictures looked. Not that it's close to getting calibrated but I was thinking at the time how much I'd gotten used to watching a crappy picture and now it's like I've got all new TV's.

:D Sorry for the long delay. I've installed the HD72 with the Draper Universal Ceiling mount and a 106 " grey screen with a black velvet Frame. I got the whole pkg off Ebay from projection depot. Dealt with a gentleman named Marc. Very happy with the service and the product. Highly recommend the company.
Anyways - I love it. The picture is perfect (no AVE, but don't really see the need for it), bright, detailed and engaging. My wife doesn't watch it much with me because she claims it's too bright!! and brings on a headache. No chick flicks for me I guess. Blacks are good, though sometimes they present themselves as a darker grey.
My son and friends are enjoying the 360 and Xbox hook ups to play games at almost life size images. The basement is one of the most popular hangouts in the neighborhood. I'm mostly watching Hi-Def tv using the Samsung Sir451 tuner. Love the hockey and bball on the biiiggg screen.
The only downside to the whole setup is the Draper Universal Ceiling Mount. The HD 72 just won't balance properly, and the weight of the cable hookups further tilts the unit. I've jury rigged a few elastic bands to level the picture. I'll be keeping an eye out for a more solid mount. If you have any suggestions - I'm listening...

A VERY HAPPY CAMPER

(Thanks for all the chat and talk about this unit You sold me!!)

Sorry, weird rule though...

Its not a wierd rule when you consider that AVS sells projectors themselves and they make a good amount of money from their sponsers who also sell projectors.

As for myself, I'm REALLY close to pulling the trigger.

I hope I don't regret not buying now due to the free lamp...

Up and running! Finally got it mounted and running. One thing scares me tho...when I set the projection type (ie, front projection, rear, ceiling) the ceiling is selected but then returning to the previous menu show rear projection icon, the image is still correct. Does this mean i'll have the dreaded reset problem and I don't have the latest firmware so i'll have to ship it back at some point? I was Optoma would at least indicate how to tell which units are updated. I purchased it the beginning of May from Visual Apex and was hoping they had the updated units. Guess i'll find out soon enough.
Bud

Budbray, you shouldn't go to 'Vegas. You have the old software and the memory lapses will shortly show up. The failure to hold the proper projector icon, even though the proper orientation will "hold" for a while, means that you will have to ship the unit back for an update at some time in the future. I contacted Visual Apex about my problem several weeks ago and told them of the problem, so they should have checked their stock.

Hey guys,

I think I am ready to take the plunge on the HD72, however I am worried a little about rainbows. I have contacts and when it is dark when I look at lights I see halos around them sometimes colored (mini rainbows). I have never viewed a DLP projector for more than a few minutes (I did not notice them then, but had never even heard of them then) so I am a little worried I may see the dreaded rainbows when wearing my contacts. Can anybody who sees the rainbows comment on whether they have similar experience with lights at night?


FWIW - I don't have contacts but do see halos around lights at night (particularly when tired). I have never seen a rainbow from a DLP projector, except when looking directly at the projector I can sometimes see a flash of rainbow through the vents. The screen image looks fine to me.

Its not a wierd rule when you consider that AVS sells projectors themselves and they make a good amount of money from their sponsers who also sell projectors..

Also keeps the forum from degenerating into a "best price spot," with hundreds of "curious newbies" asking if price '$xxxx from vendor YYYY is a good deal.' Or hundreds of "helpful friendlies" spamming the forum with "check out this boffo deal I got from ZZZZ." ;)

Yep, I got mine recently from VA and have had 3 or 4 resets already. Just got an RMA from OPTOMA and will be driving to them (50 miles away) and swap it. Now that's more than $10 on gas but I want it right away.

Have the menu icon problem, so far no resets (only 4 hrs on it & haven't fired it up yet today. Called OPTOMA US and they said if I do need to replace it, I can use OPTOMA Canada, which is in Toronto, close by. They won't let me do the update/swap till it does the reset thing...Here's hoping but the icon bugs the hell out of me anyways.

If I have to send my bosses 6200 back to him I am considering getting an HD72 as a stopgap for a 1080p 3 chip DLP (some day :p ). I read horror stories about H78/79 lamp life. Is the HD72 as bad for those that have been using it for a while? I can't currently get the free lamp deal from a Canadian vendor so this is a concern.

There are many Canadian sites now offering the free bulb.

PM me for details.

Just got the free bulb!

Question though, what is the image offset? Anyone have a formula I can use to figure this out?

I have a 92" 16:9 screen and the top of the screen surface is 13" from the ceiling. How am I doing for offset?

Thanks!

One of the reasons I need to figure this out is so that I can order my mount and/or (please no) move my screen before the PJ gets here.

I just installed my HD72 on the ceiling in the basement which is 7' 7". The projector is 14' 8" from the wall which is 116" wide and the seating will be from 12-15 feet. The picture is great but its not centered and its much too low. Any help would be appreciated to center the picture.

Thanks,

Bob

you would have to find the center in order for the picture to be center.

if the picture is too low, push the projector upward on the mount

;)

I have a little problem, maybe somebody knows the solution...

I bought a Sony DVP-NS92V (european version) and connect it to my H72i by HDMI. The problem is that if I change the format to 720p or 1080i, the PJ show "576p" signal message. I made a test with a Denon 1920 and an HDTV sat (QualiTV) it works fine. I see the correct "720p" and "1080i" messages... I made a crosstest with the NS92 and an InFocus IN76 and the InFocus show the correct "720p" and "1080i" format... What should be the problem??

^^^ Offset anyone?

Is there a calculation we can use to figure drop required? I got the whole 6.52deg bit, but trig is not a strong point of mine.

32-38% of screen height, depending on zoom level. So, for example, a 106" diag screen is 52x92. 52 x .32 = 16.64" of offset. (From the middle of the lens).

Ok, but that's for a 16:10 (full panel) screen. For 16:9 45x80 screen you'd subtract 2" from that for the 32 pixels that are unused.

Thanks!

Anyone know of a good flush ceiling mount?

Anyone know of a good flush ceiling mount?

The Chief RPA-U is working pretty well for me. It puts the center of the lens 5" below the ceiling. I'm not sure you could find a much thinner mount than that.

Optima told me that if you look at the serial number and ignore the first 4 characters (alpha or numeric) the next 3 or 4 numbers tell you the story. The numbers will yield the year and the week on mfg. if the week is greater then or equal to the the week you are good. So 0612 and higher is supposedly good to go. Just got my HD72 and it was 0607 so back it goes

I am now at my third reset. Take about 20h between them. Since I live in Canada, Optoma doesn't do the cross-shipping and I have to pay the shipping to them. (This product should have been recalled, but they told me its only a small percentage, yeah sure...) Also, I hope they fix that high pitched noise I hear since the first reset. They told me 24h turnaround and I need to ship to Richmond in Ontario. I will post back to talk about how it went.

i used the perfect mount PBLUMS.
i brought it way before getting the projector. at the time it was for the hitachi pj52.

3 legs was able to mount with screws. the fourth i had to screw to a piece of acrylic & use 3m VHB tape to secure to the projector.

it works.

i sprayed it silver to match the projector. now it looks like one object.

lots of flexibility with this mount

Has anyone purchased the HD6800 from costco.ca? It's pretty much a re-labelled HD72....wondering if its good and what the mount is like.

Can you guys post some more pictures of your HD72 in action? All I've really seen is the Fitfth Elelment and Gladiator pics posted before. I'm thinking of getting a HD72 to upgrade from my old Toshiba 36" CRT HDTV from about 6 years ago. Coming off watching a tube set for so long, I'm a little worried about being disappointed by the brightness and sharpness levels of the picture.

It's tough to know how it would look in my setup without actually buying it blind (unit would be about 111-12' from the screen), so I'd be interested to see how it looks in some other enviornments.
Thanks

Ok, here's a question: I'm going to be using the Atdec universal mount, and attaching it to the joists above my drop-ceiling, which will make for a totally flush PJ. (I need it for the offset) Will I have cooling issues? My Man Cave is fairly cool (65F) but I know there is an intake on the bottom. I figure I'm okay since it will have as much room between the unita and the ceiling as it normally would on a shelf, but I don't want to screw it up just yet :)


Also, I'll probably be looking at changing my screen fabric so what do you think of Da-Laite choices? I'm currently using the Matte White but for obvious reasons, you lose a lot in the black levels. 92" screen, figure 20fL, narrow seating area, not subject to handling, and room is almost totally light controlled.

I have their book of samples, but I thought I'd see what people like to use or might suggest.

I need assistance regarding cable setup from HD72 to Cable box and receiver.

I have a HDMI going from the HD72 to DVD player, DVI cable from HD72 to Cable box and Component cable from HD72 to Xbox 360. I currently have a red/white audio cable from cable box to receiver for sound.

I just set up Pioneer 1015 receiver but the On Screen setup does not show up on the screen? What additional cables need to be run for the best Home Theater setup?

Thanks,

Bob

I run a composite cable (single yellow RCA) from my receiver to the video in jack on the projector.

I thought about running that cable into the HTPC capture card to save the 30' RCA cable, but decided the headache of configuring through another component wasn't worth the headache.

I hope this is not true. I just ordered one from VisualApex.com and they my serial is 611. They assured me it has the latest firmware. I have not put it in action yet. Still waiting for HT to be completed. It should be done next week.

I just checked mine and it was 0612 and it seems to be ok!
