The best-decision 3LCD residence theater projectors, all bought by Epson, use 1080p imaging chips which might be pixel-shifted as soon as to double the number of pixels delivered to the screen in a single frame. That adds up to only half of the full UHD pixel-depend. Nonetheless, Epson’s pixel-shifting mechanism, sophisticated image processing, and lens optics go a good distance towards making the sharpness of UHD content aggressive with full UHD projectors. Our tests reveal that while you possibly can see a difference in the dimensions of the pixels together with your nose up to the display screen, any distinction in perceived element is difficult to discern from regular viewing distance.
