True 4K short-throw projector with HDR and 16ms input lag. The community-favorite for golf simulator use, also excellent for movies and gaming. The TK710STi (laser successor) is the new community default; the TK700STi is positioned below it as the cheaper 4K (lamp) option.

Who this is for

Honest match per persona.

Good for

Recreational Player
True 4K with HDR makes virtual courses look genuinely good, and the lamp economy keeps total spend reasonable.
Family Setup
4K projector that doubles as an excellent movie and gaming display — strong shared-use value.
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.

Not for

Performance Seeker
Lamp brightness fades over 4,000–15,000 hours; performance personas should choose laser (TK710STi or AK700ST).
Space-Constrained
0.9–1.08 throw needs more depth than tight rooms allow. Choose AH500ST or GT2100HDR instead.
Showroom
Lamp light source conflicts with the showroom premise of zero-maintenance components.
