When you start shopping, you'll find that traditional home theater projectors range from about 1,500 to perhaps 3,500 ANSI lumens maximum brightness. However, you won't be seeing all of that on the screen, because the projector's brightest preset viewing mode often displays visibly tinted color you won't want to use for watching movies or TV. In fact, it's best to assume that the projector's most color-accurate modes will deliver about half to two-thirds, give or take a bit, of the projector's full brightness spec.

The highest-resolution 3LCD home theater projectors, all sold by Epson, use 1080p imaging chips that are pixel-shifted once 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-count. However, Epson's pixel-shifting mechanism, sophisticated image processing, and lens optics go a long way toward making the sharpness of UHD content competitive with full UHD projectors. Our tests reveal that while you can see a difference in the size of the pixels with your nose up to the screen, any difference in perceived detail is difficult to discern from normal viewing distance.
Color Gamut. A projector's color gamut describes the range of colors available for reproduction. Good 1080p home theater projectors meet the full Rec.709 color gamut created for high definition content. Better 4K/UHD projectors meet or come close to the full DCI-P3 specification currently used for 4K content. You can see the difference most notably in more deeply saturated and natural reds.. Going forward, UHD projectors will eventually meet the even larger Rec.2020 gamut built into the UHD spec. 4K UHD projectors that tout "wide color gamut" will usually reproduce something larger than Rec.709, and those that promote 100% DCI-P3 are likely high-performing models. 2ff7e9595c
