4K Projectors
  3 / 3    
Know what you mean and thanks for doing the research, just I asked on facebook too and they said wait and see! The facebook people are the PR people not the engineers or developers, and given that the UHD (4K) standard includes no new 3d modes I still maintain that it's a HDMI bandwidth issue which we can *hopefully* work around. I'm still hoping the UHD will officially support 3d, the 4k DLP chip definately can, plus like I say, the thing that's been holding us back is HDMI, which generally, I hate with a passion! You made a good comment about displayport, it's been ahead of HDMI for years in terms of what it can support, however, from what I've read, display port is even worse than HDMI over longer cable runs, just something to bear in mind.

Oh, I think I see what they do (TI) , basically 4K is now native resolution and they spend 120hz on that , AND , there's another thing, probably 2 subframes have differently weighted grayscale , so the two are different. That's probably +1 bit worth of perceptual grayscale in effect, when integrated by human visual system. Problem is , with two level grayscale, you need all the perceptual extra bits you can get. And they already threw the kitchen sink at that problem (anything follows - 3D). Doubtful it's the manufacturers decision, but a reference design quality control decision not to enable that 2700x1500 120hz .

BenQ Launching 4K THX Certified Home Cinema Projector $7,999. The BenQ HT8050 4K UHD projector will be the world's first to boast THX certification when it launches on February 24. It also offers 2,200 lumens of brightness, 8.3 million pixels, a 50,000:1 dynamic contrast ratio, support for 1.07 billion colors, and sports a native resolution of 3,840-by-2,160. BenQ guarantees a clear image size of between 95 and 180-inches, but the HT8050 can project up to a 300-inch image if you have the space to go that big. http://www.benq.us/product/projector/ht8050/features/ No mention of 3D, but you'd think that these would be able to do Checkerboard @4K or Frame Sequential at 2K without shift https://www.youtube.com/watch?v=Ph3TaqPeQu0

No idea what these guys are saying, but you can see that the Acer V9800 is huge https://www.youtube.com/watch?v=jPtT4A0rQfQ

The Benq HT8050 isn't 3D. I don't think any of the Texas Instruments single DLP 3k chips do 3D. Looks like Sony is the only way to get a true 4k projector with 3D for £5000.

This one is 4K and has 3D. http://www.sony.com/electronics/projector/vpl-vz1000es
