The BenQ TH685i is a bright and responsive 1080p Full HD DLP projector tailored for gamers and home entertainment enthusiasts, offering 3,500 ANSI lumens brightness and projector‑optimized HDR10/HLG support for vibrant visuals even in well-lit rooms. It delivers ultralow input lag—just 16.7 ms at 1080p/60 Hz and an impressive 8.3 ms at 1080p/120 Hz—making it ideal for fast-paced gaming experiences . With 95% Rec. 709 (≈30-bit) color accuracy, a 10,000:1 FOFO contrast ratio, and intelligent features like LumiExpert auto-brightness adjustment and built-in auto vertical keystone/lens shift, it ensures visually engaging content whether you’re watching movies or playing games.
The integrated 5 W chambered speaker, enhanced by proprietary EQ for richer sound, and the inclusion of a Google‑certified Android TV QS01 dongle offer seamless access to streaming apps (over 5,000), Chromecast/AirPlay support, and unified remote control—though Netflix requires casting due to DRM restrictions .
