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 UHZ35ST
- Performance Seeker
Low input lag (about 17 ms at 4K/60, level with the TK710STi) and a 30,000-hour laser. At 3,500 lumens it is dimmer than the GT3900UHD and ZK431ST-B, which both cost less.
- Family Setup
4.4 ms at 1080p/240Hz for fast games, 4K for movies, and a Golf Sim preset. The GT3900UHD offers the same low 240Hz lag (4.3 ms) and a golf mode for $700 less.
- Space-Constrained
0.496 fixed throw — a 100-inch image from about 3.6 ft — fits tight rooms; same throw geometry as the GT2400HDR and AH500ST but in 4K.
