GT2100HDR
Budget and tight-space builders who want a bright, low-lag short-throw laser projector that fits a shallow room.
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.
