post #3541 of 3968
I saw it for $400 on CraigsList. But I decided not to buy it because I don't have a screen or a mount, and I don't want to have to clean out the dust or replace any bulbs. Other than the screen being larger, it seems like an overall convenience downgrade for me; especially if I happen to notice any rainbow effects. If I had a place for it (that didn't already have a KURO), I would have probably bought it.

Any advice is welcome.

I bought my HD20 new at the start of 2010 shortly after it came out. And I still use it today as my main ceiling mounted Dedicated Theater PJ. I use it for my HTPC, PS3, and xbox. FPS and every game, and BD moveis I play look and work great on my HD20. I also game and watch on several LCD monitors and TVs.

I would love to buy a used HD20 for $400 as I know my brother would love to buy it. While it's not the perfect PJ, I still feel it's worth it's "new" price and for $400 I don't see how you can do better. I prefer gaming with DLP projectors over LCD. At least in the sub $1500 range of LCD projectors I have tried.

Hello All...

I just picked up the Optoma HD20.
I have the epson 8350 for a while now, so I am fairly familiar with projectors.

I have a couple questions though.
I am going to use this for camping and outside portable movies, as well as in a home gym when not camping.

when i look at the pattern it's not complete.
it's square on the right and bottom but no straight lines on top and left side.

also this projector doesn't seem to fill the screen when watching 720P
can it be set to fill the screen, it properly detects the signal from my cable box

and lastly

when i hook it up to my desktop it works great i see the full picture i would on my monitor
when i hook it up to a poratable laptop (acer 10.8 or 11.something screen)
the left side is not visible
like the windows/start button and first row of icons?

i do set it to 1920 by 1080


any ideas?

thanks in advance.

Kevin

as far as the pattern.... it's only squared/lined on left all other sides don't have straight lines closing the pattern.
+++++++|

so it looks like that if you know what i mean?

I do, but your question/picture makes no sense to me.
post #3547 of 3968
The point of the picture is to show that when i display the test grid, my grid doesn't have 4 flat lines on all 4 sides
if has only flat lines on the right
i would think that it is supposed to be flat on all 4 sides?

that is the question
in other words

it's not a complete rectangle.

Did you try unplugging it and plugging it in again? This happens to mine a lot. It sucks, I know.
post #3550 of 3968
Hey Stonefry.
Yes i tried everything ! I ended up sending it back. Projector people are replacing it. i just hope this isn`t going to be an ongoing thing thats all! thanks for your reply!

Sorry for the late reply. I play this with PC games and movies all the time. No problems whatsoever with frame rates or tearing or anything like that. Smooth and beautiful. There are probably better projectors out there, but for $400 it'd be a steal. My biggest issue with the projector is that its not extremely durable (I've had it in for repairs twice in 2 years), but I use the HD20 heavily as both my PC display and entertainment system.

My GT 700 is dead after less than two years in a home theater that doesnt get used all that much over a years time, not impressed. are all projectors like this?
post #3554 of 3968
I have an HD320 and I am experiencing a lot of "snow" lately, very noticeable on dark scenes. My unit is over 2 years old, do you think this is my bulb or another problem with the unit? Pictures looks fine otherwise.

Hello,
I am new to the world of home theater and especially the use of hd projectors. I just received my optoma hd 20 projector a couple of days ago and I am having problems trying to connect it to my Comcast cable box( Motorola dcx 3400 with 25' hdmi cable). Whenever I connect the cable whether directly to the projector or through my receiver the image will appear for 5 seconds and then everything goes black. A faint white light is still coming out of the projector lens but nothing on the screen. If I manual switch inputs and go back the same thing happens. I have tried multiple cables and none seem to work. the blueray works fine. And I can get audio to the reciever from the cable box. Anyone have any ideas on how to remedy this?

Go into the Video menu of the 3400 and see what its set to in the "My TV Supports" settings..... change it to a lower resolution and see if it works then work your way up?

BTW, the DXC 3400 Manual says "Motorola recommends using HDMI cables less than 20metres long"

The Motorola manual is here:

I used my HD70 for 3 years before I sold it with the previous house. And I am still using my HD20 which is 2.5 years old. So I would say that less than 2 years is unacceptable and not the norm. I don't know the story behind your GT 700, do you have any other details than "it's dead"?

Definitely not the bulb. Nor can it be the color wheel. Which only leaves the DMD chip and the video processing that drives it. For testing have you try resetting the settings to default? Does the "snow" looks like little dots moving all over? Like little fireflies maybe? If you stand very close to the screen during a dark scene? If so, I have seen this with the feature called "BrilliantColor" on my Optoma DLP projectors. Where if that is turned up and if the sharpness is up, then I see snow / fireflies in dark scenes.

So if it's what I think it is, settings can make the effect much more visible.

Here is a photo from when I first setup my HD20, showing the built-in grid image you are talking about.

I just had Comcast over and they determined it was an issue with the cable box. Now have TV. Thanks for the suggestion.

Possible as well. Which is why I first asked for more details about what he is seeing. If his HDMI cable is fine, are actually any type of cable, I have seen this issue with VGA, HDMI, and Component. If it's what I have seen on my HD70 and HD20. Or he is seeing something completely different and it's possibly the cable.

With that in mind, I recommend to that person that they try another HDMI cable and even another input type like Component if they can.

My Optoma HD70 just died and now want to get the HD20. Anyone know of any good deals? I have seen $699.00 a number of places but anyone see it cheaper than that?

If you are able to find it for $699 new (not refurb) and with the standard 1 year warranty, and you trust them; then that is a great price as the normal price is $899 with some normally selling for $850.

Thanks for your suggestion. I will check out another HDMI and the settings tonight. I have used the HDMI for 2 years with this projector with no problem. The fireflies are a good description and they are more evident closer to the screen and on black scenes. I also haven't changed the settings in over a year.

Just picked up an HD20 on Amazon's warehouse deals for $690. Zero hours on the bulb (as displayed in settings, assuming it wasn't reset somehow), plastic still on the projector itself, appears to just be an open box. Originally was in the market for an Epson 8350, but they "made me an offer I couldn't refuse" on that price compared with the Epson. Unfortunately, as this is my first PJ (and first DLP obviously), I didn't realize how susceptible I am to the rainbow effect. While the picture is excellent (according to my untrained eye, at least), the rainbow effect is a deal-breaker for me. Thankfully Warehouse Deals has a 30 day return policy on their items, so it'll be going back to them in return for an Epson 8350.

That is unfortunate that the RBE is so evident to you. I was going to suggest you try a few things to reduce/eliminate the issue.
1. Maintain a 1.5:1 or greater distance from the screen. 1.5x the screen diag as a minimum distance from the screen. The greatest reason RBE occurs is horizontal movements. So the slower your eye has to travel side to side, the less RBE is evident.
2. Sharpness and contrast settings being too high, or color boosting settings, can also increase the effect.
3. Use low bulb settings.

I am hoping to try an LCD projector again some time. The last time I really used one with my setup, it was a 720p LCD and I didn't like the ghosting and SDE that I was seeing with my PS3 and so I ended up with the 720p Optoma HD70 at the time. I would love to try a 1080p LCD and hopefully the SDE is much better. Generally in the past, DLP has had a smaller gap between pixels.

Of course now I don't plan to upgrade until I am ready for a 3D setup.

After 2 years I'm finally ready to set up my HD20. (its a long story)

The room is15 feet wide and 40 feet long. The screen will go across one of the 15 foot sides.
The ceiling is about 14 feet.

What is a good ceiling mount?

Also what about a screen?
Will a 120 work or would a 135 be better?
White or grey in color?

The room will mainly be used at night to watch movies and play some video box games.

I ready to get this thing going!!!!

Ceiling mount for that high of a ceiling? Hopefully someone with experience with a high ceiling mount will chime in. Obviously it heavily depends on how far the top of your screen is down from the ceiling.

Screen size, for that size of room I would go with 135" or larger. Big variable here is front row distance from the screen. Also, your susceptibility to RBE will affect this decision as well. While I can personally get away with a 1x screen size distance and deal with minimal RBE; I still think the general 1.5x to 2x screen size distance is more optimal both for reducing RBE and eye fatigue. Though I like having my front row a little closer than I like, so it's a different experience while gaming. But then generally sit in the 2nd row for movies. Again, a lot of personal preference going on here.

If you haven't already, I highly recommend playing with the HD20 on a table/stand and your wall to see what size you prefer and how far you want the front row from that size image. Then test for RBE and general eye fatigue with that test setup. Maybe even watch a full length movie to see what you think.

White vs Grey. Another big topic. I have tested both in my environment and prefer white with my bulb on low. Testing both is a pain and you have to deal with returns, etc. If you have a dark colored room and watch in darkness or very low light; then I would stick with white. Another factor for me was cost. I was testing my DIY white 125" screen against a cheap 120" grey screen. And preferred the low cost white screen material.

While there is a lot of opinion and choosing yourself by testing in your own environment is best; if you want to skip the testing, then I think a white 135" screen with a 1.5x viewing distance, trying to keep the center of your screen only slightly higher than your eye level while sitting down and not reclined, is a great default answer.

But you could test and find out you prefer a 120" grey screen at a 2.0x viewing distance. lol.
