Eh... I’m not so sure about that. I don’t see “perceived” anywhere on the product page. TI actually refers to it’s 660TE solution (.66 DMD) as having a “true 4K resolution” of 3840 x 2160 “on screen”. Of course they’re counting the DMD, the processor and the actuator as one complete system and in that respect you could make the argument...
I don’t know. Judge for yourself.
In either case, it’s not like TI are the only ones to point fingers at here. Check out Epson’s description of their 4K enhancement:
“Using the projector's 4K Enhancement Technology, you can receive 4K (3840 × 2160) signals and project ultra high-definition images. This technology shifts each pixel diagonally by 0.5 pixels to double the image resolution.”
I love how they throw in the “double the image resolution” but don’t specify what is being doubled.
But that’s not the half of it. Check out JVC’s description of their E-shift:
“Experience absolute presence as images seem to float in mid-air, and you forget the existence of the screen. Be totally immersed in the world that is portrayed, as images envelop you. Beyond 2K is a new world of moving experiences that only 4K can deliver.
JVC's e-shift 3 technology is able to reproduce the finest nuances and unique tone of every visual work, enabling you to enjoy a 4K-resolution* image with extreme realism and presence in your home theatre environment.
*3840 x 2160”
I mean, they don’t even elude to the fact that half the pixels are missing and yet no one bats an eye. But if a DLP manufacturer doesn’t specifically mention in every part of their product description that there are less than 8 million mirrors on the DMD then someone grab the pitch forks! Lol!
I don’t know. I’ll keep calling it what I have been: pixel shifted 4K. That seems to be the most adequate description. Meanwhile, I’ll be referring to JVC and Epson’s solutions as 4K simulation— because that’s what they are.
