Description
The BenQ TK700ST is a short-throw 4K UHD projector purpose-built for home entertainment and casual gaming in rooms where the projector must sit close to the screen. It casts a 100-inch image from around 6.5 feet away, with 3,000 ANSI lumens of brightness and a 10,000:1 contrast ratio for a bright, detailed picture. Dedicated RPG, FPS and Sports game picture modes are tuned for different genres without sacrificing true 4K UHD detail, and input lag is rated at 16.7ms at both 1080p and 4K, dropping to 4.2ms at 1080p/240Hz for fast competitive play. HDR10 and HLG support add extra contrast and colour range for supported content. Dual HDMI 2.0b inputs with eARC, a 5W speaker chamber and auto 2D keystone correction make the TK700ST simple to set up for console gaming and movie nights alike, in rooms too small for a standard-throw projector.
