Very explanatory Bob "with are either 1080p native, but accept and process a full 4k input signal, but with the ability to shift each pixel half a width at a few thousand times per second, causing the illusion of 4k, Dlp chips should also be about , not sure but these use a native res between 1080p and 4k with rapid shifting." I would expect prices to go down a bit to buy me a 4K projector because the price is very high right now
