Wondering what this thing will be like?
From what I have been reading, it is expected to have pretty low native contrast. Talking business class level contrast.
That's unfortunate......such promising news with pricing and native 4k, but sounds like the other attributes will drag it down...
It uses the Texas Instruments 4K chip that was introduced earlier. http://hometheaterreview.com/optoma-unveils-2799-4k-dlp-projector/
Gotcha. Whereas The JVC and Epson "shifting" delivers about half the pixels, correct?
By the way, this I just saw from Evan Powell...."...The 4K DLP chip starts with double the number of mirrors as a standard 1080p imaging device. But each mirror is capable of defining two separate and distinct pixels on the screen in alternating scans--the pixels do not overlap as they do on 3LCD pixel-shift machines. Again this happens so fast that it is not perceptible to the eye. So it is misleading to say that the 4K DLP chip has half the number of "pixels" as a native 4K chip -- it is technically correct to say that it has half the number of mirrors. With this technology there is no image processing required to blend the first and second scan. Projectors that use this chip are fully able to address all pixels in the 4K signal and put them on the screen. So we have no problem categorizing this chip as genuinely native 4K based on the fact that the image that it produces consists of the full resolution of the 4K signal...."I just thought this was interesting. Now, am I arguing that it's even in the same ballpark for overall PQ as the others we've mentioned...not at all. Just interesting...
I want some screenshots/explanation of how "the pixels do not overlap", it just doesn't pass the smell test. If the fill factor is >50%, then the only way for pixels to not overlap is for them to be shifted one entire chip width or height away, but that's "not possible". On top of that it doesn't jive with any of the official information we've seen from the likes of Barco. Or the screenshots we've seen taken from these machines with 4k test patterns.It really seems to me like TI (marketing) is doing it's best to obscure the issue that these new shifted DMDs work with overlapping pixels, just like JVC and Epson. They're sticking to their 4Mpix DMD, which flashes twice for each frame (4Mpix * 2 = 8Mpix), but gloss over that those two fields overlap and thus are not equivalent of a native 4K imaging device.
