The Epson Pro Cinema LS10000 4K Enhancement Projector ($7,999) is a premium projector in every sense. High-priced, and worth every penny, it delivers both high-end conveniences—like motorized focus, zoom, and lens shift—and high-end technologies, like its 4K enhancement to boost resolution. The result is extraordinary image quality, even for the high price, and an easy pick as our Editors’ Choice premium home theater projector.
The LS10000 is a significant step up in every way from the Epson PowerLite Home Cinema 5030UBe 2D/3D 1080p 3LCD Projector, our preferred pick for a moderately priced 1080p home-theater projector. Along with the higher price, the LS10000 is built around different technologies for imaging and for its light source, offering what Epson calls 3LCD Reflective technology instead of standard LCD chips, and lasers instead of a traditional lamp.
Not Really 4K, but Close
The LS10000 isn’t actually a 4K projector in that the native resolution for the 3LCD Reflective chips is 1,920 by 1,080. However, it accepts 4K input and shows images at full 4K resolution. According to Epson, the 4K-Enhancement Technology shows two images per frame, shifting the image by 0.5 pixels diagonally between the two. That puts twice as many pixels in the projected image as are on the chips, doubling the resolution to 4K (3,840 by 2,160).
The technique is similar in some ways to interlacing on old CRT monitors, which used to reach high resolutions by drawing the even and odd lines of each frame in two separate passes. With those older monitors, however, drawing the image that way often causes visible flickering, because of low refresh rates, which leaves a relatively long time between passes. Epson doesn’t publish a refresh rate for the LS10000, but the company says it’s sufficiently fast to ensure the two passes are close enough together that there’s no possibility of seeing flickering. I didn’t see any in my tests.
