I'm almost afraid to ask but I noticed the spec sheet listed keystone correction as 5%. Is that only a couple of clicks?

If my trig is right, it's approximately an inch per foot (tan(5 deg) = 0.0875). If you are throwing 20 feet, you can compensate for a maximum of 20 inches of vertical displacement with the keystone adjustment (with some image degradation, of course)

Do I have a HD200x lemon?

With a black projected image, I notice a patch of lighter area near the bottom left
corner of my screen. Although not as noticeable watching a movie, it is definitely
noticeable under certain conditions. Has anyone else noticed brightness variations
projecting a black screen? An easy test is looking at movie credits.

Add this to my issues with PS3 1080p 60Hz output (lines through image. Sometimes
it's only 1 line. Sometimes it is 2 or 4.), makes me wonder if I should swap it.

Don't know how many people saw this, but projector central is gearing up to
post their HD20 review soon! Here is a short synopsis from their site:

"Then comes the Optoma HD20 next week. This is one of the first 1080p projectors to market with a price tag of $999. The HD20 delivers a beautiful picture for the money. However, we see more rainbow artifacts on it that we do on more expensive home theater projectors. We'll get into this in detail in the review."

It looks like the pro reviews are finally on their way. Hang tight everybody!

Can anyone comment on the HD20's black level compared to the HD70? I'm hoping for a little improvement. If not it may not be worth upgrading for me.

To my eye, the black is much blacker than on the HD73. That is after calibration. The easiest place to see pure black is in the background of the on-screen menu. Wait for the professional review, though - my eye could be deceived.

Interesting that they mention rainbows. I have noticed just a few more rainbow artifacts than with my previous PJ (Mitsu HD1000u), and had chalked it up to it being a newer, brighter bulb, though maybe the color wheel speed or segment # is a little lower than my previous PJ. It's not easy to see them, requiring rapid eye movement while viewing a high contrast border such as screen credits. With my previous two PJs I always noticed more RBE during the first few days, and then gradually "lost" them as my brain gradually re-trained itself, so I expect the same thing with the HD20.

That's good to hear as I believe the HD73 has better blacks to begin with than my HD70? It does seem my HD70's blacks have improved as the bulb has dimmed - I'm at around 800 hours - but I'd still like to see an improvement.

I don't recall any uneven pattern on a black screen...but will check again tonight. The lines through image I have not seen - yet - have only had PJ for about 5 days. Can you get the same problem with a different 1080p source (if you have one that is)? I have noticed that the HD20 does seem to take a long time when syncing up with different input sources.

Anyone have one of these and a PS3? I'm very interested about gaming on this projector. Is it fast enough for high speed fps and racing games? Back in post 285 Dreamwriter mentioned a delay of 23ms... is that anything to worry about? I'm coming from CRT so I'm not used to delay issues. I need something to play Need for Speed games on; my son's 5th birthday is coming up.

Sorry if this has been covered but I have a issue I hope you can help me with.

I've watched movies on the BD370 for about a week (connected to my Optoma HD20 with HDMI) and just realized the player was set to 1080i res. I switched it to 1080p and now it (the projector) will not connect to the LG. Is this a BD problem or a projector problem?

Ok guys, I need some pointers here.

My HD20 will be here tomorrow. I have a 119" screen, a mount, and a 35' "flat" HDMI cable running from my Onkyo 507. I thought I was ready for a quick projector install but I ran into a problem...

I was hoping I could duplicate my HTPC connection (1920x1080@60). One VGA feeding my 56" DLP, and an HDMI feeding the HD20 through my receiver. Everthing forks great but the receiver keeps dropping the HDMI connection, in turn, I loose sound to both. I want to use my 56" to surf the web and view email. And I want to use the HD20 to watch movies on (MediaBrowser, Hulu, and Blurays).

Should I just run a VGA splitter to feed both my 56" and the HD20?? Is it possible?? It says it supports resolutions beyond 1920X1080.

Also, I found an awesome "flat" 35' HDMI cable.... Do they make those for VGA as well. I have to run the cables under my "non" dedicated HT room carpet.

Thanks guys,

It sounds like you have a defective PJ. Brightness variations may be normal but the lines are not. I would try to exchange it ASAP. Please keep us posted.

Good luck

assuming your hdmi cable goes direct from bd player to pj, turn both off, let set for a minute or so, then turn on pj first, wait a moment or two, then turn on player.
this lets the hdmi/hdcp 'handshake' take place.

might help.

Tried that. Ended up changing "1080p display mode" on the BD370 from 60hz to 24hz and it worked. Not sure I'm happy with this solution though.

I saw where you later said it works if you changed the BD370 to 24fps, that suggests it could be a cable bandwidth problem. 1080p at 60hz requires more than twice as much cable bandwidth than 24hz.

My guess is that either the length or quality of the cable or connectors or something along the signal path is not up to delivering a clean enough 1080p signal at 60hz.

It isthis cable. Only $11, so you're probably right. It is 24AWG, would 22awg make a difference (thats the biggest I see at monoprice)?

Yes you want to pick up the 22awg cable. Will 25ft be enough distance for you though?

Another new HD20 owner here. Upgrading from a Mits HC1500. I've only been able to play with it for an hour or two, but I've got to admit these projectors seem to be pretty buggy. I mean various other users have posted about strange issues when changing inputs/resolutions. We have people who get those lines across the screen etc.

For me when the resolution, or basically any setting like 16:9 to native changes, the colors get all messed up for a few seconds. Goes from green to pink and then everything goes back to normal. So not a huge deal, but concerning that the problem could get worse.

Another thing I noticed in just limited viewing without even looking for it, was a subtle flickering type effect on certain scenes in the couple BDs I popped in. I could only really notice it on aerial landscape type shots like the IMAX ones on Dark Knight and a few on the Incredible Hulk. Hard to describe but it seemed like the lighter areas in the shot were changing brightness ever so slightly. This is on 1080p 24hz with the PS3. I thought maybe it was the AI people were talking about earlier in the thread, but that is off by default.

I also have to say I didn't honestly know what a rainbow looked like with the HC1500, but I do now with the HD20. I went looking for them which was probably a mistake, but it wasn't too terrible so I'm hoping to "learn" not to see them over time.

The good news is I do think the blacks on this projector are a notch better than the HC1500, and of course the extra resolution is noticable (only watched BDs so far). Not as big a difference as I had hoped, especially when viewing on a 100" screen from ~12', but noticable none the less. The colors seem pretty similar out of the box. Haven't had anytime to do any tweaking or calibration either.

So all in all it's a mixed bag for me so far. I do not think I am a picky or highly discerning viewer, as I've only ever owned "budget" level A/V products and been very happy with them.

We'll see how things play out as I get more time with this projector. Hopefully these buggy issues and the rainbows go away, and I can enjoy what looks like a pretty damn good image for under $1K.

Just saw this projector is available at BB. Unfortunatly, they are selling it for$1099. If they were selling it at $999 that would be awesome combined with a 12% off coupon. But maybe they will lower their price. We'll see.
