Hmmm, I went to Ultimate Electronics over lunch. The sales guy tried to tell me the Optoma GT720 is scheduled to be available this month and will have HDMI 1.4 as well as 3D Bluray compatibility? He told me they delayed it just so it could have this when released.


Anybody know much about this projector?

No, I don't have any info on it. I do know that Optoma has said that they will have 10 3D projectors by June and that some of them are supposed to work with 3D Blu-ray. Obviously, this is not a Full HD projector (native resolution of 1280:800). I am looking forward to what Optoma has up its sleeve.

It will be fine for me. I am only going to set the projector up when I want to screen something 3D. I like my current 1080p 2D theater setup just fine.

I like the ultra short throw too. Should work Ok for me.

I am skeptical of what he told me though. It does not seem like this is going to be the one to me after reading some other links on this one.

If the Optoma GT720 has HDMI 1.4 that would be great. I am looking for a 3D projector but I really want to be certain 3D BluRay will be supported. This model might be it.

I see nothing in any of the links to indicate that this pj will support BD3D. In fact it seems to be specifically marketed as a gaming pj.

I am skeptical. He seemed so darn sure though.

Seems like it's the same 3D Ready compatible stuff as the everything else.



I was hopeful somebody here would of known different.

John I hope I'm wrong. But you would think that if Optoma had found a way to integrate BD3D compatibility into this model, they would be touting the fact all over their website.

cineo32 series 3D stereoscopic projectors

Quote:


The cineo32 series is available in special versions for 3D stereo display. Using Infitec Wavelenght Multiplex Imaging, the same as Dolby3D technology, a set of two projectors can be set up to show passive 3D stereo for small or large groups. A complete kit includes two projectors with pre-fit filters, and six pairs of filter glasses.

The great benefit of using Infitec technology is that no special screen is needed, and left/right eye stereo separation is independent on angles. That means they can be used in motion platform simulators, visualisation caves, and other environments where the image may be at an angle towards the user. Using standard polarised light technology, these are all shortcomings.

Another great benefit of using cineo32s with Infitec stereo technology is that the filters can be deactivated at will, and remote controlled! This means that switching from stereo to mono in the midst of a presentaion is easy, so where higher brightness and no stereo is needed, it is the simple and best solution.

I know I may sound like a fool here, but has anyone thought (or is it possible) about an HTPC with 2 display outputs that can send the signals to different projectors? I know that with the prices of 480p and 720p models this isn't that expensive to have 2 projectors (I've seen some 720p's in the $500 range). Does it absolutely have to be 1080p for you to consider it? I am just guessing here, but if you had 2 projectors would you need to worry about refresh rates since each projector is only doing 1/2 the picture, or overall brightness since there would be 2 bulbs going? I have been happy with my 480p projector and even though we watch HD at my friend's house on his projector I don't sit at home wishing I had it, until my bulb burns out and I replace it. But it isn't a deal breaker.

Two factors make this somewhat challenging aside from the expense even using an HTPC.

A. Your screen must be able to maintain polarization, and it just so happens such screens are not so great at all for 2D viewing.

B. You still can't really use just any old PJ. Many do odd things polarizing the light in at least one color before it leaves the PJ.


This is what I wanted until I really looked into it. I am just waiting for some 720p relative cheapo compatible DLP to come available. The other factor for me with it? It has to be compatible with both 3D BD and Broadcast 3D. The broadcast part is really iffy right now using an HTPC and even 3D BD hasn't really been tested on an HTPC yet as well, as far as I know anyways.

So, with dlp, you keep the screen you have, hook up your source(s), get some active glasses and your there.

Anybody know much about this projector?

This was found at the GT720 product page of optoma.com:

"Optoma projectors cannot be used to display 3D TV broadcasts or 3D Blu-ray discs. Optoma projectors may support these applications in the future but will require additional hardware at extra cost."

If this is true, it doesn't sound good for this product.

Never again will I post something a "sales guy" told me. Dang it.

I tried arguing it with him, but that was like wrestling with a pig in the mud.

Yesterday I could not get the model to come up on their website.

I realize this is an ignorant question, but I'm going to ask it anyway - hopefully, I'll learn something.

Anyway, obviously FP 3D technology is out there - in theaters, right? What is so different about having it in the home? Is this a technological issue? A cost issue? An availability issue?

To put it another way - would it be possible to play the MvA 3D Bluray in a 3D-equipped commercial theater?

The theaters, for the most part, are using passive polarized 3D, along with a silver screen. That works great in a dedicated 3D theater but doesn't work well at all in a home theater due to the requirement of projecting both 2D and 3D. Silver screens hot spot in 2D. The Dolby 3D passive 3D system does not require a silver screen because it uses a "color wavelength difference" method of 3D projection. This is available to consumers who have big bucks because they need dual projectors and other support hardware.

The answer to home FP 3D will lie with DLP using a 1920x1080 DLP chip. This will require active shutter glasses. There just haven't been any announced. They may appear at either INFOCOMM (June) or CEDIA (Sept.)

3D theaters use hard drives to store the movies. The compression system is Motion JPEG2000.

Unknown if it would work. It might. It wouldn't look very good blown up on a 30 to 50 foot screen though. BIG difference between consumer HD/3D and professional HD/3D

Ok, so it seems it's a little bit of each - technology, cost, and availability. A few follow-up questions (thanks in advance for your time and effort):

Would someone with the "big bucks" Dolby system be able to play the MvA 3D Bluray?

Do the theaters with the silver screen method show nothing but 3D? Or do they switch back and forth (every few months or whatever) based on what's being shown at the time?

I'm assuming the DLP 1920x1080 chip will offer the "full 3D" resolution, unlike what's in the Mitsubishi "3D ready" DLP's, right? Is this something that's in production or in development?

On a related note, are there any FP DLP's that could use a similar system to the RP DLP's using the 960x1080 chip? And will there be RP DLP's that utilize the 1920x1080 chip or will that be exclusive to FP?

AFAIK, yes. All that is required is to seperate the L & R views sending them to the different projectors, one showing the Left view and the other showing the Right view. If you go back in this thread - look for a post of mine on the SIMS 3D PJ system.

Quote:

It's a little different with a commerical theater due to the size of the image. I believe they do show 2D digital movies on their silver screens which BTW do pump up the contrast ratio. But hot spotting can occur.

Yes - a 1920x1080 DLP chip does have the availablity to offer Full HD per eye. Unknown what is coming but it would be a natural for HT 3D for consumers using the frame sequential 3D presentation format with ASGs - no silver screen required though a higher gain white screen might be a good choice.

Current 3D FP DLP PJ's are 720P only (max). Only Mitsibishi continues to sell DLP RPTVs.

IMO, FP PJs aren't going to use a half HD per eye 3D system. Better to offer a Full HD per eye system for marketing purposes and percieved PQ.

Except for this one.

Although at 1400 x 1050 it's still not 1080p.

Aren't they native 16x9 AR format?

From your link:

The F10 AS3D has been designed primarily for the requirements of scientific visualization, simulation and mathematical modelling, making it easy to display geotechnical data analysis, and other graphically challenging applications, such as game development and design feasibility studies.

Look here.

I only see 4 with a native 1280x720 resolution. The rest seem to be computer desktop resolutions (1280x800, 1024x768, 800x600).

Right - 3D for Gaming. But not for watching 3D movies or 3D TV.

I just received my new issue (#147) of Widescreen Review today and editor Gray Reber had an interview with 2 representative from the US JVC Technology Center and a marketing Assistant VP from JVC Professional Products. Overall the interview covered a lot of 3D topics, and included a lot of confused and misleading information. However, during the interview when asked about JVC plans for a 3D projector the following points (not direct quotes) were made by the JVC representatives:
  • JVC is planning something this year
  • it will be using shutter glasses and will be fast enough to alternative right/left images
  • they are willing to accept having a dimmer image using the single light engine and shutter glasses approach in order to keep price down (as compared to using dual light engine and polarized glasses approach)
  • during the general discussion on 3D displays it was made clear they think 144 Hz (i.e., 72Hz per eye) will give better results than using 120Hz (60Hz per eye) but they did not specifically say their upcoming projector would use a 144Hz display rate when fed 1080p/24 (per eye using the frame packed HDMI format) from a Blu-ray 3D player.

What News! I may be able to keep my hipower screen yet.

Even with reduces brightness of active eyewear, it still may compete favorably against passive dual-engine models since there is at least a 50% drop off with polarized light methodologies.

In any event, this well be an EXCITING Cedia!!!

1080p and lossless audio. EVERY BD should have them both.

But there is a 65% to 85% drop off in brightness with shutter technology (50%+ loss due to each eye only receiving a image less than 1/2 time plus the transmission loss thru the LCD lens of the glasses when in the open state.
