Room planner
See each one in your sim room.
The planner draws each unit to scale with your room and your swing: where it mounts, the throw it needs, and whether your shadow crosses the light. Put in your room once, then switch units in the planner to compare.

Better for GT2400HDR
- Cost-Effective Buyer
Best brightness-per-dollar in the budget tier now that GT2100HDR is being phased out — same 4,200-lumen laser short-throw at $1,299, with current-model retailer availability and warranty.
- Space-Constrained
0.496:1 fixed throw fills a 100" screen from 3.6 ft. Same tight-room geometry as the GT2100HDR with the assurance the model will stay carried by retailers for the next few years.
- Recreational Player
1080p but bright enough for daytime garage play; laser life makes it set-and-forget. The budget Optoma to buy today; the GT2100HDR it replaced is no longer sold new.
