Epson followed using pixel shifting on 1920 x 1080 3LCD chips. This was a radical new approach to getting substantially higher picture resolution out of native 1920 x 1080 D-ILA chips. The revolution began with JVC's introduction of pixel shifting in 2013. The chip's physical resolution, at least in the home theater world, has become irrelevant. In our new reality of 4K resolution and pixel shifting technologies, there is ZERO correlation between native resolution (the number of physical pixels on the chip) and the actual resolution of the picture you see on the screen. So we all grew up KNOWING that the 'native' resolution of the chips was directly related to ultimate picture quality on the screen. Anyone in the projector biz could tell at a glance just from looking at pictures on the screen what the native resolution of the projector was. Visible pixelation (the screendoor effect) on lower resolution projectors was supremely annoying and desperately to be avoided. When comparing these projectors there were obvious differences in detail and image sharpness. There was a massive visible difference in picture quality between SVGA and XGA, and between WXGA and Full HD 1080p. People are concerned about what is true or genuine 4K and what is fake or 'faux-K.' What is the difference, and is it anything to worry about? In the end, as we go about categorizing and defining these products, the practical question is what makes a 4K projector 4K?īack in the day, the native resolution of a projector was a big deal, and rightly so. The revolutionary technology of pixel-shifting has injected a lot of controversy and confusion into the world of 4K projectors.
