![]() High dynamic range (HDR) support: Most 4K projectors now support the standard HDR10 format some support HDR10+, but only a few support Dolby Vision.Real-world results are almost always lower. For a living room, look for a rating of 3,000 ANSI lumens or more. For a light-controlled home theater room, a good rule of thumb is to look for a projector that claims brightness of at least 1,500 ANSI lumens. The larger the screen, the more brightness you need. Light output: A good 4K projector needs to be bright enough for you to use the projector with a large screen (over 120 inches) and still enjoy a vibrant, well-saturated image, especially with HDR video.Some videophiles contend that only native 4K projectors should be called 4K projectors, but our testing has shown that the level of detail possible with pixel-shifting is 4K, and we’ve concluded that the results are good enough for most people. The projectors we consider all use pixel-shifting to show a 4K resolution on screen: The image-creating chip or panels have a 1080p resolution, but by rapidly shifting the pixels four times to show the image, they produce the full 4K resolution on screen. Some high-end projectors have a native 4K resolution, which means the image-creating chip has either a 4096×2160 or 3840×2160 resolution-but those projectors cost more than $5,000. Resolution: The projector must show a full 4K resolution on screen. ![]()
