Projector shopping for a golf sim goes wrong in a predictable way: people buy on lumens and resolution, hang it, and discover the throw distance means it's mounted where the ball flies. Short throw is the spec that matters first, and the TK710STi is built for exactly this job — a big, sharp image from close range, so the unit sits behind the hitting zone rather than in it. Beyond that the numbers are well judged for a home bay: 4K UHD at 3,200 ANSI lumens, which holds up in a garage that isn't pitch dark, and a laser light source instead of a lamp, so there's no bulb to replace at 2,000 hours and no gradual dimming to explain away. Input lag runs to single-digit milliseconds in the high-refresh 1080p modes, which matters more for console gaming in the same room than for golf. It sits sensibly between the cheaper Optoma units and BenQ's own flagship — for most rooms, this is the one.
