If you are not using the Plasma and the HD20 at the same time with the iScan Duo, then it sounds like you are using it like an HDMI switcher. If you can not figure out the issue with the iScan Duo in the mix, I would use an HDMI switcher instead. You can try connecting your PS3 directly to the HD20 with the cable already connected to the HD20 and see if you still get the HDCP message. Not all HDMI cables and not all displays are the same sensitivity for HDCP signals.

I still think that you should use an HDMI switcher instead. They are also much cheaper if you don't need both displays running the same signal at the same time.

Thanks xenon2000, today I tried connected ps3 through my hd20 directly and it worked fine. so what's wrong with my iscan duo??. That's weird. I don't want to unplug and inplug it everytime. My space is very difficult to do so...

You would need to call DVDO about the iScan Duo. If you only need 1 display at a time with your PS3, I would buy an HDMI switcher instead. It's a much simpler device and usually less issues.

These are not current models, but it gives you a quick idea on what I am talking about and what price range they are.

Amazon and ebay have a bunch of good ones as well.

Anyone mounting this pj upside down on a shelf with the middle cut out? I assume upside down wont work on regular shelves due to the lack of ventilation, but with a hole cutout, or with a horse shoe shaped shelf, it will vent fine. Is my thinking wrong?
post #2015 of 3969
Are you talking about mounting it under the shelf upside down, screws through the shelf, using the proper mounting holes on the bottom of the projector, or sitting it on top of the shelf upside down, and affixing it somehow that way?

i am using something similar but with some space between the shelf and pj.

There is nothing wrong with this setup. The exhaust is out the front. And as long as there is space on the sides and rear, it doesn't matter if there is no space on the bottom of the projector where the ceiling mounts are. This is a perfectly ok way to mount the projector.

You could mount it upside down on a shelf, on three large rubber bumpers screwed or glued to the shelf. If you go an extra step you can create a "mount" by attaching the bumpers to a separate small piece of wood. Then you can raise and lower the pj by stacking stuff between the "mount" and the shelf. Adjustment of the pj would be really easy with this setup. Just keep the front and sides clear.

Hi all, I have spent countless hours/days researching and i Just Bought my hd20 online thru costco... woooo wooooo... the downside costco charges taxes: the upside, they have a great return/warranty policy and give an additional year coverage for free AND... I CAN WALK IT RIGHT INTO THE NEAREST COSTCO as oppose to having to ship the unit in the event that something goes wrong...
This will be my first projector and I am so excited....but i do have a few questions that i was hoping to get help with:
1 Considering an Elite vmax2 120" good or bad choice for the price?
2 have no choice but to run a 75ft HDMI cable from my comcast hd box to the projector (not going thru a receiver just straight to projector) has anyone on here done this successfully? cables are from monoprice.com...if not will i need an hdmi extender/booster and do they actually work??
3 the projector calculator shows that for a 120" screen at 14'3" i will need to be at 1.10x zoom, will this zoom setting affect my picture quality?
4 where can i get a calibration disc (what disc is suggested) or do i need to send it to optoma for that? I actually live 15minutes from Optoma which is kinda cool...
5 Lastly, where are most people actually placing their seating with a 120" screen? is it closer or further from the screen that is suggested by the projector calculator?
sorry for so many questions guys ! I have actually read all the posts within this thread in addition to 100's of others on other forums but still i have questions.. go figure
thx in advance for the ear

hi there
wanna purchase an hd20, i have a few questions regarding
firstly, i haven't had the chance to see one yet, how does it compare to hitachi pj tx200 or 4805, these are the ones i have owned before. black level? screen door? also i read its kinda loud? how much so? i have a silent pc, dont really wanna have a 30dB pj near my ears, should i build a hush box, or is it ok?
the max projection distance i could use is 13.7 feet, what screen size should i aim for? (cant really have more place than 100-110" diagonal) btw do i have to place the projector at the center of the screen, or can it be opposite to the side of the screen if you know what i mean... with the tx200 i could play with the lens shift, i know i am vertically limited with the hd20, how bout horizontally? (i have a window opposite to the center of the screen, and the ceiling is like 13 feet high)
what kind of screen size and type shoud i aim for? i have light yellow walls, btw DIY screen, furniture board for my previous pjs, but nowdays screen prices are much more affordable. will it be an improvement btw? koz if it wont be much better, i might build another one like this, for like 20$

No benefit at all. I have my HD20 on a shelve in my bookcase along my back wall. The HD20 projects perfectly from there.

I too got my HD20 from Costco. It was cheaper than other no-tax online retails. And so even with taxes. I think I spent about $30 more than the tax free online places. Well worth it for an extra year of Costco warranty. Plus I have 90 days to try it risk free with a full refund to everything including shipping. Gotta love Costco.

As for the 75ft HDMI cable. Seems many people have 1080p issues with cables longer than about 30-50ft. So my guess is you likely will have issues.

Zoom setting on the projector will have no optical degradation to the image. The only thing affected by zoom is light output. But the HD20 is so bright that at 120" screen size with bulb on low, you won't have an issue with brightness at any zoom level. Just stay away from digital keystoning as that will affect the image. Also just make sure you don't put the projector at either extreme of zoom to fit your screen size. Otherwise you lose one direction of zoom adjustment to fine tune the borders once installed.

I having figured out my seating yet with my 125" screen. So no comments on that.

I don't have the links right in front of me, but as for calibration. I would not get too technical on that with colorimeters, etc. Just remember that if you calibrate on 1 input, it's technically not calibrated for all inputs. In general, I would pick your main input and calibrate that. You can buy a general calibration Bluray disc to use.

For performance, no. But there are certainly reasons that people choose ceiling mount. For me, I have had reasons for the 2 rooms I have done so far.

First issue is that with the HD20 and HD70, and many DLP projectors. The image offset from the lens is fixed. So you can't just put it half way up a wall to projector straight infront of the lens to the wall. So if you have limited vertical placement of your screen the projector has to be either close to the ceiling or close to the floor.

If not on the ceiling, that means that the projector has to be on a table in front of you if you want to sit in the center of the screen. And if the projector is in front of you, then you have to sit further back if you want to have the HD20 far enough back for a big screen.

If you sit closer, you have to not use the center area. Which might be fine for you. But then more of the image will be blocked if someone walks in front of it. Where is it is ceiling mounted, you have a larger walking area that won't block any or little of the light from the projector.

And the final reason for me to ceiling mount, is alignment. I like knowing that it will fit the screen each time I turn it on. No fine tuning from it being bumped on a table. But that is a minor reason and certainly that alone does not outweigh the portability advantage of a table top solution.

thanks for your help and input!!

I had the Screenplay 4805 before my 720p HD70. And I now have the 1080p HD20. First, the HD70, I felt, was way better than the 4805. At the time I was using a 100" 16:9 screen. I found the HD70 resolution of 720p way worth the upgrade from a 4805. I enjoyed my HD70 way more than the 4805. And at 100" screen size, the resolution was extremely obvious between the two. If you have a PS3, xbox 360, upconverting DVD player, or a computer hooked to your projector, you will love the difference in picture on the HD20's 1080p resolution!

Fan noise on the HD20 and HD70 is also quieter than the 4805.

Screendoor? LOL, I had it with the 4805, but even just moving to the 720p HD70 that was long gone. And so with the HD20 there is also no screendoor effect. At least at 125" I don't see any even ultra close to the screen. Maybe if you sat 5 feet from a 200" screen. Maybe.

If you were happy with the 4805 fan noise and other things, then the HD70 and HD20 blow it away in my opinion.

I too have an ultra quiet HTPC in my theater. Even with the speakers muted, I would say my HD20 and computer are close to the say volume. Though they are both about 10-15 feet away from my ears where I sit.

Personally, unless you are going to have the projector literally right at ear level and close to your head, I don't see how you won't be happy with the HD20. Also the HD20 and HD70 are some of the quietest projectors around. I know there are a tiny few with lower db ratings. But most projectors are much louder than the HD20.

The HD20 and most DLP projectors, do not have any lens shifting in any direction. They also only have digital keystoning which you should avoid. So most DLP projectors must be placed center to the screen. They also have a fixed vertical image offset. So the image it not projected straight out from the lens. It is projected higher then the lens. The Projector Central calculator will show you how much of an offset from the lens center based on the distance and screen size you choose.

Is 13.7' the size of the room or the max that the front of the projector could be? Since it bases the distance from the front of the lens. If your room is 13.7' or about 13' 8", then the max for the front of the projector is about 12' 11" from the wall. Less if add a screen.

So that gives you a 16:9 99" to 118" image size on your wall at 12'11" distance from the lens. With a 7.8" to 9.3" image offset, meaning the distance from the lens center to the bottom of the image.

These are all numbers from the Projector Central pro calculator.

So basically with most DLP projectors, you basically put your screen where you want it and you pretty much have only 1 place it can be ceiling mounted and 1 place it can be table top mounted. With the only variation being a 2 feet of back and forth distance from the screen.

Hope that was helpful.

I do want to mention one thing. Most ceiling mounts, retail and DIY solutions, once installed; really don't take a long time to remove just the projector. Sure, it might not be a few seconds. But my DIY solution has 7 screws to undor to remove my projector, 4 if I want to leave the HD20 attached to my mounting plate. But even the full 7 screws wouldn't take more than 2-3 minutes to unscrew. Of course redoing the alignment is where the real time general comes in for when I re-attach it. But some pro retail ceiling mounts allow projector detachement and reattachment without greatly affecting the alignment.

Of course with a table top solution, you have to re-align anyways. So there is time for that either way.

Just saying, that if you are not moving the projector literally every other day or more, then if having it ceiling mounted improves your seating and viewing experience for your indoor viewing; I would go ceiling mounted and just deal with unscrewing just the projector as needed.

Xenon,
thx much for the reply
according to the projector calculator i should be ok with a 120" screen, but i just wanted to get some real life feedback.... I am gonna ceiling mount for sure... after reading your reply, i ordered a mount... lol...... I hope to be able to receive and hook it all up this weekend as it has already been shipped according to UPS tracking...
decided to not buy the screen until i get the projector and do a test run from 14'3" to see if i can fill a 120" screen correctly at that distance...
what screen did u go with?
any opinions on these two electric screens:
elite vmax2
mustang screen from costco

I would not install the ceiling mount until you have the projector. Since the mounting need to have the center of the projector lens to be centered with the screen. So it's very likely and possible that the projector mount interface with the ceiling is not centered with the projector lens. So if you install the mount with the ceiling interface centered with the screen, the projector will likely not be centered with the screen. So I would make sure you have both in hand to verify everything.

As for screens, I have tried 2 pro screens in the past. One was $700. I didn't keep either. I didn't find the PQ much, if any, better than my DIY screen. My current and last screens are made using black out clothe stretched on a fixed frame. If you can't do a fixed frame setup and roll down are your only option, I am not much help as I didn't like what I tried and don't remember what they were now. That was 4 years ago. lol.

Hey everyone,

First time using a projector. I picked up the Optoma HD20 system and just have been projecting on my wall and I love it. I want to mount the system on my ceiling but I need something low profile and as close to the wall as possible. Do you recommended the MonoPrice mounts? Let me know if you have any other suggestions.

Anyone used this for the HD20? Do the screw holes in the HD20 line up with the mount? Does it feel solid? I am all about saving money but not at the cost of having my projector fall from the ceiling. Any other mounts recommended? Thanks for advice?

I haven't used that mount. But I would have tried it if I didn't have an angled vaulted ceiling. I don't see any reason why that wouldn't work on the HD20. It's 3 adjustable arms and the HD20 has 3 mounting holes. You might have to supply your own longer screws and/or washers. But looks like it would work fine. 6.7" isn't exactly "low profile" in my opinion. And that is to the projector mounting, so it's more distance to the lens center. $15 plus shipping sure is cheap though.

How about this mount? It has a 4 inch drop from the ceiling.

FYI - the exact same mount is on amazon for less plus i think it qualifies for free shipping if you spend five bucks more on a cable or something you may need anyway.... but on the other hand, the Ebay sellers user name (kramerica_incorporated) is awesome.... hahahaha only if you are a true SEINFIELD fan (the tv sitcom)

For those that can spend a bit more, the Chief RPA-U is very popular. The HD20 feet are only around 2-1/2" from the ceiling (lens CL 5"). It's also a very well built mount and comes with the M3 screws. If you want it high and tight you really can't go wrong if you can spend the $100. Use a port saver from monoprice though, it's tight getting a thick HDMI cable all the way around.

hey all, my hd20 came in the mail today (costco)... I stopped everything and set it up on the nearest wall i could find. Middle of the day, sunshing bright and all...... hooked it to the vga out of my computer and Voila ! it worked...
set it at 14'3 away from the wall hoping to get a 120" picture or 105"x59".
result: unit definitely throws a 120" + picture.... looks great ! even in the daytime took pics with my iphone but they are terrible compared to the real thing and its midday in a room full of windows but im happy still

Well after going back and forth between the viewsonic pro8100 and the mitsu hc3800...maybe i just don't want the headaches. Seems like everyone has problems.

Are any of you long term HD20 owners having any consistent problems? Or is it just the normal odd breakdown?

Also I have and HD65 right now which I like quite a bit. I'm sure the HD20 can't be so bad....

Can anyone who's had the HD65 -> HD20 comment on the fan noise? I've always found my HD65 a bit too loud.
