    BenQ TK705STi 4K UHD Short Throw Smart Gaming Projector

    The BenQ TK705STi is a 4K UHD short throw projector built for big-screen gaming and home entertainment in tighter rooms. With 3000 ANSI lumens, a 0.8 throw ratio, 4LED light source, and an industry-leading 5ms input lag at 4K 60Hz, it casts a 100-inch image from just over 2 metres away while delivering blazing-fast response for console and PC gaming. Google TV is built in, so streaming, casting, and smart control all work out of the box.

    Cinematic 4K UHD Visuals

    True 4K UHD (3840 × 2160) resolution paired with 98% Rec.709 colour coverage and support for HDR10, HDR10+, and HLG means rich, accurate colour and lifelike contrast across films, sport, and games. The 4LED light source delivers up to 30,000 hours of viewing in ECO mode with no lamp replacements ever required.
