*Official* Optoma HD20 Thread - Page 111

Ah, a repeater... I have seen issues with those. How far is your HD20 from your xbox? I use a 35ft HDMI cable and have had no issues with any of my devices. Granted, it is a thick 22ga cable.

Unfortunately due to not being able to pass the HDMI in the ceiling the whole way...I have a 50ft cable. Works fine for the dish but not strong enough signal for the Xbox...hense the repeater. Have two, one was still giving noise out in the picture...so might very well be the same.
Not truly noticeable unless it's totally a black screen, which is rare. But of course I "know" it's there..

Not sure I follow. Are you saying you have a single 50ft cable that is not long enough so you use 1 or 2 repeaters? Or are you saying that 50ft "of" cable reaches your projector? If so, I am sure your issue would be solved with a single 50ft 22ga thick cable and no repeaters.

It sounds like he has a 50ft cable, but is having problems with his Xbox signal. He has tried two different repeaters to boost the signal to no avail.

Not sure the repeater will have much effect, since its at either end of the 50ft run. What you may want to do is get a higher quality cable than the one you're currently using, as Xenon suggests.

Is 50 ft the shortest run you can use? How far away is the projector? Mine is 16 feet away and I'm able to use a 30ft monoprice cable, with absolutely zero issues. It even has a 6ft connection on both ends (wall plates), for a total of 42 feet with two connectors.

I dont see what the Xbox settings are. I think that's the issue and they need to be posted.

Reset it to default http://support.xbox.com:80/en-US/xbo...oot/kb/xbox-kb

See if it works. Or try basic settings.

Console setting
- HDTV: 480

I tried HDMI amplified switch from monoprice. Horrible results. I ended up buying a new pioneer AVR and all worked out.

I have this one, works like a charm with my xbox and HD20

So speaking of video games. I just tried hooking up my Nintendo 64 directly to the composite input, and I get nothing. I get audio out of my stereo, so I know that the Nintendo is on, but its not getting a video signal. Worked fine on another TV.

I did a google search, and it appears someone else had the same question earlier in this thread, but it was never resolved. I could find no other info on this. Anyone else get their Nintendo 64 to work?

hard to say... If you had a receiver that did video upscaling then I bet it would work..

Well yeah.

Don't have one.

Lol N64.... Just let it die! Its not as fun as you remember. I have one with Goldeneye and Perfect Dark and Mario Kart. Its has nearly unplayable graphics and its incredibly repetitive.

Nope, the N64 via composite will not work with the HD20. Sorry. You either need to buy an S-video cable for your N64, an AVr or other signal converter.

Looked just fine on my 56" HDTV (and my 27" sdtv) when I played Goldeneye yesterday. Nostalgia is great!

I have a 50ft cable (due to the fact I couldn't pass the cable in the ceiling the whole way...finished ceiling and not enough space to pass it). Otherwise I could have used a 30ft even 25ft no problems. And I had to use a repeater to boost the signal from the Xbox...the dish worked fine but the Xbox signal was full of noise. So now I have a 3ft cable from the Xbox to a hdmi switch...50ft to the repeater and a 6ft to the HD20.
The picture is good...but on fully black screen such a Gears startup...you can see small lines in the screen...now it's not visible during game play or movies...but I'm wondering just how much quality I'm losing due to this.

Like I said I'd debating on trying the Xbox with a short cable to see if this still occurs...if so. Well then I'll have try and find a solution. The cable doesn't seem to be the issue as I had no problems with the dish signal.

The Xbox is an older 60gig unit as well...could be an issue, but I'm going to try different things to see what I can get out of it.

Hello! please help me
is this video noise normal? http://www.youtube.com/watch?v=C6r3aJmEIyo
it is highly noticeable on grey color, even without any input it has same noise on menu

Are you talking about the sparkles?

Yes, it is has size of one pixel, and flashing very fast

Its a bad HDMI cable I have a 3ft monoprice HDMI thats a sparkle cable.

but even when i disconnect hdmi it is the same

Better close your eyes!

what do you mean?

If it isn't the cable its the unit. Firmware is only available from Optoma if you ship it in.

As many have already said. Yes, it is normal. The little fire fly like noise is normal and common of many low cost and even higher cost DLP projectors.

Now the moving bars is not normal. But I suspect that is simply the refresh rate of the camera and projector fighting each other.

But also notice how close you have to get to see that noise. I NEVER see it on my 125" screen at normal seating distance. I too have to be about 2 feet from it in person to see it.

I would be shocked if any firmware would change it as it's heavily part of the video processor and likely the chipset not firmware.

FYI, I have seen this digital noise on many projectors for years. But remember, you shouldn't notice or even be able to pick it out from normal viewing distance. If you do, I would adjust your settings because you likely have sharpness and/or brightness too high.

I realize there is a sale section here, but I figured it would be most productive to post here.

I have an optoma HD20 for sale! it has 55 hours on it, and was purchased right around two months ago. My wife has changed her mind about our basement set up, and I'm going to have to get an 8350 for lens shift to keep my theater.

there is nothing wrong with this projector, well taken care of, no scuffs, drops, or anything bad has happened to it. comes with everything, cord, remote, box, etc. I'm entertaining offers, anything reasonable will be accepted. if you have any questions please feel free to PM me.

I know the hd20 is a great budget choice, its why I bought it, but if here is your chance to be even more economical and help out a fellow member at the same time!

*EDIT*
I didn't realize you had to pay to list an item for sale, out of courtesy to the community I have purchased an ad in the appropriate section as well. http://www.avsforum.com/avs-vb/vbcla...do=ad&id=16374

I recently bought a HD20 and am looking to mount it on the wall. I've vaulted ceiling, and can't mount it on there as i also have a ceiling fan. What wall mounts have you guys used? I bought a Vantage Point CGUPM6 from frys but it didn't work. It sucks that almost no other retail stores carry projector mounts here in dallas metroplex.
So can anyone recommend any good wall projector mounts?

Well I have order an adapter for the HDMI switch to see what this will do, and I also did some calibration finally last night.
Used the one from "custard" or something like that. Seems to have help the "noise" pixels I was seeing, but now I find it is almost to "black" on the blacks. Might have to play around with a little more, could just be that the brightness was just to high from what it is now...went from 50 OTB to 38 with the calibration.

Why would that stop you?

Most wall mounts for inverted setups I've seen are regular ceiling mounts with some sort of DIY bracket to hang it off the wall.

My room is fairly small ... with a throw distance of 14'. And my screen is 92". So i want the projector to be as far back as possible. And i've a inwall speaker installed in the vaulted ceiling just above the place where i want to wall mount my projector. So if i try to mount it on the ceiling, i'll be hanging it right in front of the speaker ... so thought wall mount is my best option.

Cacophonix - that sounds reasonable, but 14ft throw won't work. With a 92" 16x9 screen the max throw distance for the HD20 is 12 ft.

For the inverted wall mount I would install a shelf and use a ceiling mount below it.

As others have said, 14' is too far for a 92" screen. User the Projector Central calculator.

The HD20, like many low cost DLP projectors; does not have lens shift and the zoom range is tiny.

With a 92" screen, I would recommend putting the HD20 as close to the screen as possible and putting it on a coffee table. For 92" screen you can put it 10' away. Of course that would put your large seating at the back of the room and then split seating to both sides of the projector.

The projector will always project upwards. So either close to the ceiling or close to the floor are your only options and little variation in distance from the screen.

Not that you'll use this mount in your situation but just wanted to point out that this mount works perfect with the HD20.

It's solid and easy to adjust and level. If you ever move your projector where you can use a ceiling mount you can just reuse this one by simply not using the elbow.
