GT2100HDR
Budget and tight-space builders who want a bright, low-lag short-throw laser projector that fits a shallow room.
~$1,199 approx 2026 street price (~$1,199, often under $1,200)
The value short-throw pick that fits the tightest rooms: a compact 1080p HD laser projector with 4K/HDR10 input support, 4,200 lumens, and a 0.496:1 throw ratio that covers a 12-foot-wide screen from under 6 feet of throw. That ultra-tight number is the whole point, since it lets you mount the projector well clear of the swing in shallow garages and basements where a longer-throw unit can't fit. A 30,000-hour laser engine is the longest in its class, fast 8.6ms response keeps shot-to-result lag invisible, and it draws up to 45% less power than Optoma's old lamp models. For most home sims it is the best brightness-and-throw-per-dollar projector.

Common questions
Will the GT2100HDR fit a small room?
Yes. Its 0.496:1 throw ratio is one of the tightest available, covering a 12-foot-wide screen from under 6 feet, so it suits shallow garages and basements where longer-throw projectors won't fit.
Is 1080p enough for a golf simulator?
For most home setups, yes. The GT2100HDR is native 1080p but accepts 4K HDR input, and at normal viewing distance the 4,200-lumen brightness and low lag matter more than native 4K resolution.
