Is the BenQ TK705i right for you?
Good for
- Console and PC gaming: BenQ claims 5 ms at 4K/60 and 1080p/60, with FPS and RPG game modes
- Streaming without extra hardware: Google TV (Android 11) built in
- HDR10, HDR10+ and HLG content
- Built-in sound: two 8 W speakers (16 W total) and an eARC-capable HDMI port
What to plan for
- The 5 ms lag figure is BenQ’s claim, not an independent measurement
- No high-refresh mode is published: BenQ lists 23–60 Hz
- No lens shift listed and a fixed 100% offset, so the mount or table height has to be right
- Native Netflix on its Google TV system is not confirmed
- Light source rated for 20,000 hours in Normal mode (30,000 in Eco)
