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 AK900ST
- Showroom
6,000 lumens with lens shift and BenQ's golf features, in the throw the LK936ST used. For a premium room with windows or a large screen, this is BenQ's current top answer.
- Performance Seeker
Bright enough for data review with the lights on, 18 ms of lag at 4K, and Auto Screen Fit to keep the image square on the screen without a calibration session.
