The TK850i uses XPR technology to project 4K UHD resolution onto the screen with compatible content and features HDR10 and HLG compatibility to produce a wide color gamut for vivid colors. It outputs up to 3000 ANSI lumens of brightness and has a 30,000:1 dynamic contrast ratio to help produce details even in dark areas of the image, which is particularly useful for dark movie or video game scenes. The projector has two HDMI inputs for connecting your digital HD devices such as a gaming console, Blu-ray player, or cable/satellite box. Its two built-in 5W speakers eliminate the need for external speakers if none are convenient. The TK850i includes an IR remote control for additional convenience.
