Description
The BenQ TK705i turns a living room into a big-screen entertainment hub, combining 4K resolution with a maintenance-free 4LED light source rated at 20,000 hours in normal use and 30,000 hours in Eco mode. A 600,000:1 contrast ratio and 98% Rec.709 colour coverage, powered by BenQ CinematicColor and HDR-Pro, give vivid contrast and cinematic depth. Built-in Google TV brings Netflix, YouTube and other streaming apps straight out of the box, and the TK705i is one of the few projectors in its class with USB-C charging (up to 30W), letting a connected device charge while gaming. Console gaming is well catered for with input lag as low as 5ms at 1080p, 2K and 4K. It can project up to 150 inches with flexible throw distances, runs as quietly as 24dB, and includes HDMI 2.1 connectivity with eARC and 7.1-channel audio return for pairing with a soundbar or AV receiver.
