Optoma HD66 - First 3D home theatre/gaming projector - Page 38

I believe it is just like the GT700/720, you need to use the VGA in and run 720p @ 120hz for 3d.

When you say your projector did not recognize any 3d content, what do you mean? The projector doesn't have any indication when the content is 3d (in fact, it can't even differentiate between a 120hz standard windows desktop and 120hz 3d).

If the problem is that the displayed image is in 2d, it's probably some setting in stereoscopic player. One thing to keep in mind is in many situations stereoscopic player defaults to 2d mode unless you put it in full screen. Find the hotkey to turn on 3d mode (is it F7? can't remember...) then put it in full screen and switch to 3d mode via hotkey.

The only thing the '3d' options in the menu do is control the dlp link, so be sure that's turned on so your glasses will sync to the projector.

Does anyone use this projector with PowerDVD10? I believe PowerDVD10 has the ability to convert movies to 3D on the fly (correct me if I'm wrong with the correct software that does).

If so, how does it look to an actual 3D movie? Good, bad, ok?

How is the brightness in 3D for this projector? I understand a lot depends on the screen, just wondering for an overall consesus. The panny TV's seem to be so dark in 3D.

And, with the conversion kit, has anyone watched 3D content with DirecTV? If so, is it pretty cool?

Finally, with the conversion kit, has anyone used a PS3 for gaming / playing 3D movies? How do they turn out?

I'm really considering picking one of these up straigt for 3D, but wanted to know these questions first before i pulled the trigger.

oh ok, i thought the projector when receiving 3D content would show a 3D symbol (don't remember where i got that info from)
So maybe its working them, i;'' try ti with my glasses tonight
thanks

If you pull up the menu, the GT700 will tell you if it's in 3D mode or not.

I have the Optoma HD66 . I can turn on 3D modein the menu. Infact i can leave it on all the time (doesn't seem to make a difference)

So i should be good to go then?

-Just hook up HDMI from laptop to projector
-output set to 120hz 720p
-sterescpoic player input SBS output Page Flipping
and put on dlplink glasses and i should be watching 3D?

Yep. Might have to hit the button to tell the player to go into 3d mode, and be sure the glasses are on, that's pretty much it. You'll know whether the player is sending 3d because the screen will show a "double" image if you look at it without glasses.

What the 3d option in the menu actually controls is whether or not the DLP link flashes are sent between frames, so if it's off it'll still display the 3d images, but your glasses won't align with the projector so you'll probably still see the double-images.

As reported in the projector central review of H66:

3D Brightness
" No matter what projector you use, there is always a dramatic drop in lumen output when using 3D content. For example, the HD66 produces 1979 lumens in Bright mode. Once you turn on 3D mode, lumen output drops to 660. This is the maximum lumen output possible in 3D mode, since no matter what mode you are using, the HD66 ignores your settings after making the switch."

Does anyone know why there is this large drop to 660 lumens (from 1979 lumens) when 3D mode is selected? Is this reduction in lumens different in each of the modes (Bright, etc.)? Is the lumens reduction always the same percentage of the lumens before 3D mode is selected?

The HDMI input works fine for 3D on the GT700

I'm wondering, does anyone know how this would compare to a Sharp DT-510 in 2D mode? I'm wondering if they would both have similar video quality.

I sit corrected. I haven't had time to play with this much yet - but am happy to hear it. I guess I'll be able t use the laptop for 3D on the screen for now, until my new vcd setup later this year.

is the BD-XL still coming?

I think i'm going to be buying the HD66 tomorrow for gaming and movies and I have 2 questions if someone can answer them for me:

1)Does this work well with gaming (is there input lag)?

2) What is the actual diagonal screen size at 10 foot throw. If I look at optoma's website (88") I get a different answer than the manual (much smaller than 90" I believe) which also has a differnt answer projector central (91"). I'm hoping for at least 90". These numbers are with the zoom which i assume doesn't affect the image quality since i believe it's an optical zoom.

So what is correct?

I have the HD66 and my screen size matches the calculator on Projector Central.

There is not much zoom available and I didn't notice any difference in image quality.

If you mean the 3D-XL, according to Optoma's, Facebook page, it's still "Coming soon".

I have the HD65 which is exactly the same throw ratio as the HD66.
My projector is exactly 10 feet from the screen and it gives me 6 feet 4 inches from side to side and 90 inches diagnal at 4:3 ratio.

I myself am getting the HD66 soon and once I do I'll just be replacing it with my HD65. And because my mounting and screening is already done with my HD65 it's just a matter of replacing the projector. So I lucked out there. I'm just waiting until the 3DXL until becomes available.

Hope that helps.

I'm kinda new to this so maybe someone already covered this but if someone could just help me; I just bought the Hd66 and HD content appears beautifully, the only problem is that the motion blur on it or some people call it judder/jitter whatever; the movement of objects just ruins the experience. I'm sending the video from my blu ray at 1080p24hz, shouldn't the 120hz refresh rate be enough to eliminate this?

How does this effect 3d watching ? (i'm still waiting for the 3d-xl) Shouldn't there be immense ghosting with this motion blur?

I think the problem is in the projector itself. will sending it 720p change this? Maybe when I send 120hz content it will show normal motion.

PLEASE someone help me with this!

Does this bother anyone else but me?
I just upgraded from an infocus 800X600 DLP and I don't remember the motion being so bad. also the blu ray isn't faulty because I had it hooked up to a flatscreen and everything worked out great.

Any advice or help?

If your bluray player is sending 1080p@24hz, you shouldn't have any issues with judder; You can tell by looking at the mode displayed when the projector locks on to the signal from the player - is it showing 24hz there? If not, your player may not be set to send 24hz.

Yeah when it locks it does show 1080p @ 24hz, and the motion is still blurry. Maybe the term judder isn't exactly what I'm trying to explain, but just simple motion blur.

In that case what you're seeing isn't judder... I haven't noticed any sort of motion blur like you describe, but I don't often watch 1080p@24 material... Try 720p, see if it fixes what's bothering you. The good side of 720p is that it won't be scaling, but the bad part is that it's not 24hz that way, so you'll actually be adding motion judder.

I'll try that, would you think the Brilliant color would create any lag as well?

Has to be scaling artifacts...

I have done nothing but send 720p @120hz to my GT700 and it really seems amazing on that note in particular. My HTPC is doing the scale on Bluray media.

I have had my HD66 for about a week now and have used it for both gaming and movies. Gaming has been awesome on it. I have been using Nvidia 3d Vision on it. I have played a little bit of several games to test it out (Just Cause 2, Fallout New Vegas, Darksiders, DC Universe Online, Transformers and a few others). I did not notice any input lag even on a fast paced game like Darksiders. I was using my 360 controller. The best thing of all is that I didn't notice any ghosting in any of the games! That was a revelation for me after gaming on my Samsung 22 inch for the past couple of years which did have noticeable ghosting on most games (not terrible but noticeable).

I do have one issue though, that maybe someone else has experienced. I am using TMT5 as my 3D bluray player. After watching a movie I have noticed that when I go to play a game I get the red warning about "atttempt to play 3d in a non-3d display mode" or something like that. Has anyone else experienced this? The only way that I have found to fix it is to reinstall the video drivers.

Hi all from Australia,

Just pulled the trigger on one of these last week. Got it for $799 Aus which whilst more expensive than the U.S is a great price for Down here (a shop in Sydney charging $1341 for example - so i'm pretty happy!) I'm told they sell lots of them and it's recent stock. Therefore it's had the firmware update. I'm going to run it with nVidia vision initially. With the updated firmware is it a case that once connected to the pc with the latest drivers it will just work in 3d without having to hack the .inf file? That was the kind of outcome I was looking for.

Cheers

Steve

Yes with the latest firmware you do not have to hack the .inf file

Awesome! Now I just have to not so patiently wait for the projector and PC bits to arrive

cheers

Steve

I'm happy to say I've just ordered a HD66 in Australia aswell.

I'm replacing a Infocus 4805 which gave me 6 and a quarter years of outstanding viewing pleasure but finally is coming to an end (colour wheel gone, light tunnel collapse).

With a bit of luck the mount I have for the 4805 (non universal) will be compatible with the HD66 but I'm not counting on it.

The throw distance is way different anyway, so I'll be re-installing. But sticking with the same screen (92" HCCV on home made frame).

Looking forward to the extra pixels and brightness!

Cheers

Can someone point me to a link, or post, about using this Projector with 3D blu-rays please?

Can't quite get my head around what's needed. Can it only run through PC for movies. Or can I use the PS3 with the 3D-XL adaptor, etc.

Thanks :-D

A PS3 + 3D-XL will work fine, if you can get your hands on a 3D-XL (or one of the adapters from a competing company). A PC will also work but that will take more experimentation since there are so many different hardware and software combinations.
