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
