The 1st Official Infocus 4805 Thread - Page 101  

Yeah, I have to start playing around. Which do you think I should focus on first? I'm thinking about putting black curtains on the sides of the screen and about 6 feet along the side walls as well. Maybe spray paint the first 3 rows of tiles black (also 6 feet). And throw down a dark rug. There's no way I'm ripping out the grey carpet or couch since they are both new and cost a couple thousand $$$. Hey, I built the room before I knew about AVS or FP! Wish I stumbled in here a year ago and the color scheme would have been different ;-)

Has anyone made a DIY mount that you could run a DVI, Component, and Svideo cable down through the center tubing?

I would like to try to start looking into mounting this to my ceiling and I know it's going to be tough. First of all, I have a vaulted ceiling it will be mounted to. There is no way for me to mount it to the back wall since I cannot get access to that area to drop the wires. Is there a good mount that can swivel and also run the wires up the middle of the pipe. This needs some WAF to it, so no wires hanging out.

Also, what size screen should I go with in a 16x15 room? I can get either a 100 or 106" for the same price. Are there any downsides going to the 106"?

Here is how it's going to mount:See image

Thanks to Kras, Mandarax and many others I just about completed by setup with a 4805 and Da-Lite HCMW pulldown and Mandarax's mount. Just to give you a chuckle, I gotta tell this story.

Got the mount earlier last week (quick shipment by Mandarax, thanks!) and the pj came in late Friday. I knew the screen wouldn't be here for another 10 days but couldn't help myself, got the pj hanging from the ceiling Saturday afternoon. Then, of course, I looked at the BlueJeans component cable and just had to hook things up! Since I don't even have a wall to project onto (it's pointed to a huge stone fireplace floor to ceiling) I had to improvise. Well, looking in the back yard I got my inspiration. A lot of you with kids involved in soccer know about KickBack goals, well, we have one when fully extended is 16'x8'. I had to shorten everything as much as I could to get it into the house, down to about 12'x6'. So there I am, with a still large frame and net setting in the living room, my next step is to hang a blanket over it. The only thing I could find was a fuzzy white backing on one, so I then dug in the linen closet to find a sheet. The only solid color I could come up with was a light tan, so I strung it over the top of the goal. Here it is, wavy from the blanket and net underneath and HUGE wrinkles from being folded up, but I had a screen! Fired up the 4805 and WOW!!!! can't keep the grin off my face! This may have been a mistake, now I really can't wait for that screen!

Anyone who hasn't seen the 4805 in action, even under much less than desirable circumstances such as mine, would just have a hard time understanding how good a picture it can project. You just gotta see it!

Now off to figure out how to fish that huge component cable through the ceiling, at 3/4" diameter it's too big to hide on the wall, even with a raceway...

Martin Butler,

My understanding is it is an DVI receiver on the projector- the HDMI is just a forward compatability adaptor. But you would not get HDMI extras like 480i and audio. At least that is the way it was back on the SP7200, and I asume for cost reasons the same DVI input was used.

UnknownShadow,

Throw up a 100% IRE field and look around the room. The brightest things are the most bang for the buck!

Very positive and detailied review up at http://cine4home.de. Some interesting stuff on the design of the colour wheel I was not aware of. Check it out in Bablefish.

Yes I have been waiting for Cine4Home.de review! Bablefishing now!

Some highlights!

I feel somewhat redeemed now that my shootout findings are being confirmed.

The colorwheel is optimized for D65 with excess red to counterbalance native blue/green lamps.

lamp is masked to shine only on chip - responsible for high contrast. Rather than marketing controls like white peaking or blue/green gain.

blues/red are dead accurate standard - green is pale towards yellow (this is how you get brightness)

D65 is "almost astonishing" reference flat out of the box.

brightness spec is exceeded by 10%, while contrast is nearly 10% off spec, though with white peaking controls it is over 10% of spec. (This explains why contrast fell before it was introduced - engineering won over marketing)


My favorite bablefished quotes...

"A contrast of 1800:1 during correct 6500K attitude, reaches otherwise practically no other projector under € 2000. - without aufwaendige "Nachbesserungs" work, radix complement to engineers"

"Here it shows up clearly that engineers the projector not only on the pure technical and at the same time very insignificant data of the product descriptions (contrast, lumen etc..) optimized, but also on the just as important parameters, as akkurate colors, which unfortunately only too often fall due to one-sided marketing of many manufacturers and dealers under the table. We would like to praise this carefulness in the equipment tuning here expressly and to call the other manufacturers to take itself hieran an example"

BobWilliams - if you are lurking come take a well deserved bow!

Well, I called DaLite this afternoon to see if they could explain the difference in my two samples of the HCCV material. Unfortunately the rep I spoke to could not.

I half expected this outcome and I guess that leaves 2 possibilities:

1.) DaLite has improved the material but the rep is clueless. Perhaps DaLite does not like promoting the fact that they change their materials. This doesn't exactly improve relations with existing owners. Who knows however.

2.) The HCCV material suffers from inconsistencies in the manufacturing process. This is the much more disturbing possibility. Clearly the 2 samples are subtly different and if these differences were not intentional, that's pretty sad.

I plan to follow up with an email asking the same question, just to see if I can get an answer out of someone else. I'll probably just wind up buying the material and then attending some religious services. Why can't this stuff be easy just ONCE!?

Yeah I knew the 4805 had to have some "Nachbesserungs" in there somewhere :D .

jtdman, check your PM.

I have had my projector for 3 weeks now and I am ready to mount it to the ceiling. The problem is the room is surrounded with concrete. I guess I have to run the cables up the wall and over. If someone has a recommendation for laying out the cables, please let me know. Also, is everyone installing an electrical outlet in the ceiling for the projector?

Actually "Nachbesserung" means "rework". So what I said in german is that the 4805 is practically the only projector below 2000.- which makes accurate D65 colors at maximum contrast without any rework (Tuning, filters etc.).

:)

---- Thanks for the explanation Ekkehart , I had no idea what the word meant I was just being silly ;) .

So are you dissapointed that there is no "Nachbesserung" involved since that is how you guys make your money selling tweaked projectors? I think there are a bunch of tweakers here just looking for something to fix - but they had to turn their focus on the room setup instead ;-)

On the subject of "something to fix" ... my continued disappointment with SD cable PQ has led me to the fount of OTA HD; that is, off-the-air reception of local station hi-def (yes, the rabbity-eared past becomes the future once more). Putting up a HD antenna plus whatever amplification/tuner gear could double the number of HD channels in my area (combined with cable). I know it's off topic, but this particular forum is a sort of catch-all HD source for us (maybe not so anymore) newbies. Will post comments and pics when I can compare cable HD with OTA HD on my 4805.

Heh, you need an HTPC and a high speed internet connection ;)

s'plain please. Are you suggesting I look at streaming internet for HD content?

I get it ... MyHD or similar. Thanks (I think).

Sent you a PM. Enjoy. ;)

My fave translation:

"A disturbing side effect, the so-called rainbow effect is connected with this technology. Spectators with sensitive eyes see a farbaufteilung with strong contrasts in the picture, a kind farbblitzen."

Farbblitzen? Isn't that what Volkswagen was bragging about just a few years ago?

acksnay,
I think I'm hitting the RatShack for an indoor UHF-HD antenna tonight!

Madpoet,
I think I might be interested in a PM too please.

acksnay,

LARUE,

I though Comcast was required by law to rebroadcast OTA HD in our area - DaGamePimp have you compared yet? Ratshack stopped making the good indoor UHF one a while ago. I was watching OTA HD on my POS tube TV's because it was such a better broadcast. But I am sure Comcast will find a way to screw it up - like recompressing or something stupid.

Madpoet, acks and larue

I want that same pm plz :D

Madpoet if you are passing out the keys to a hidef porn site - you are going to have everyone PMing you. Not that I am trying to get one of the mods in trouble - I have no idea what you are PM about. But I bet you get more PM now! ;-)

No, I think it's actually one of Santa's reindeer. :D

Seriously, I just wanted to say to Ekkehart that I thought you did an excellent job reviewing the 4805. I always enjoy your reviews and I think they are the best on the net - in any language. As you can tell, however, many of us are a little frustrated at the quality of the "translation" done by Babelfish. I think if you were to publish English versions of your reviews, you'd get quite a following here. Something to consider...:)

Actually, if my high school German still serves me, I believe the literal translation of the word is "color lightning". I think that's a little more catchy than "rainbow" if you ask me.

Ekkehart

I subscribe to htprojectors.com so I do not have to BabelFish their reviews - I would be willing to do the same for Cine4Home.de. Then I can have the fine German engineering reviews to contrast with the fine Italian design reviews ;-)

The only drawback is hearing you guys say how poor the PAL is on these NTSC machines ;-)

If it worked for Volkswagen - it can work for projectors - we no longer have rainbows we have color lightning! "Infocus - powered by farbaufteilung". Marketing.....just send the royalty checks to me....;-)

If your refering to the one that resemebles a small perferated dish Ratshack is selling them again.
Or at least the Scappoose ratshack has them
I have this one with a flip up element plus the rabit ears
from Jensen after playing with it i found i get the best signal strengh as measured on my Sony KD34XBR's diagnostics mode
when the flip up unit is open all the way and facing down at the TV
I went from 82% to 89to 90%
I will eventually do the waffles on different planes for all OTA channels
:)

So I went to my local R- Shack and they had the out of stock #15-1880 Antenna that was sorta favorably reviewed at: websitehdtvexpert.com/Pages/squareshot.htm
I dropped the $40, brought it home, hooked it up, and nothing ... not one channel.

I'm sorta pissed 'cause I can pretty much see the towers from my house and I've already tried some 15-20 year old Recoton (which was crappy back in the day) that managed 2 local channels.

So I screw around with the thing for an hour, different orientations, gain settings on its internal amp, and I can't get jack. Plus the wife is getting bugged.

Then I remembered something in my closet, Farbblitzen!!! I run and retrieve an old UHF Hoop Antenna (Wife rolls eyes).

"I almost got TV-49 with this thing ten years ago ... the digital channels here are UHF, this just might work!"

I twisted the brown antenna leads of an old Snap-On 'F' Connector on to each end of the hoop, and slammed that baby onto the HD receiver's antenna jack. Hit the "EZ Scan" and ... still nuthin.

No just kidding!!! 12 Digital Channels!!! Farbaufteilung I've done it!!!

I was a little too late to catch CSI from the top so the missus requested HD Olympics. She still loves the 4805 (me she's not so sure about).

RatShack's getting their fancy Buck Rodgers antenna back tomorrow.

Hey Madpoet ... where's my PM? :^>

The obsolete - but best RadShack HD/UHF looks like a gold cookie baking rack. I have a couple that I have modded with the soldering iron to get a better F-coupler on there. Somewhere.......amazing how things dissapear when you move....

The local Comcast HD broadcasts are actually crummy IMO , I think they are too compressed . Discovery HD is awesome and the INHD channels look good when they have true HD and not some old B-movie that has been upconverted . I find most of the Comcast sdtv to be terrible , even the Faroudja does not help much here IMO . I have decided to use Component for the Moto6200 since the DVI out is not impressive [ it functions but it taint purty like da HTPC via DVI ;) ] .

--- I still cannot get a clean 1280x720p via the HTPC DVI connection , it syncs and shows 720p but it looks awful IMO .
--- 1024x768 is a mess too , even in 4:3 mode .
--- It's not all bad though : 848x480 via DVI is simply perfect , my 4805 has the sharpest focus that I have ever seen [ on any PJ , and I have seen many ] . I must have lucked out and got the wrong lens , should be on a 7205 ;) hehe .

--- I should also confirm that a dual link DVI-D cable does indeed work with the InFocus M1 to DVI adapter [ my adapter showed up today :D ] .


------------------ Jason

My German is non-existent so I couldn't understand the conclusions on PAL playback quality on the German test. Can anyone enlighten me?

I asked this question some time back in this thread and I thought the consensus from the guys on this side of the water was that PAL showed hardly any difference to NTSC on DVD. It would be good to hear comments from those using PAL.

My 4805 arrives this week and I hope I'm not going to be disappointed!
