Who each one is better for
Honest persona fit, side by side.
Better for TK700STi
- Recreational Player
True 4K with HDR makes virtual courses look genuinely good, and the lamp economy keeps total spend reasonable.
- Cost-Effective Buyer
The cheapest path into 4K sim. Lamp life is the tradeoff; if you want laser longevity, step up to the TK710STi for ~$700 more.
Better for UHZ35ST
- Performance Seeker
Fastest 4K input lag in the segment (4.4ms) with a 30k-hour laser; brightness and longevity both at the top of the mid tier.
- Space-Constrained
0.50 fixed throw fits tight rooms; same throw geometry as the GT2100HDR and AH500ST but in 4K.
Both fit
- Family Setup
