4K UHD laser short-throw with low published input lag — about 17 ms at 4K/60, level with the BenQ TK710STi's 16.7 ms, and 4.4 ms at 1080p/240Hz for fast gaming — and a laser Optoma rates at up to 30,000 hours (it does not say in which mode). HDR10 and HLG. Includes a 'Golf Sim' picture mode preset. Fixed 0.496 throw (100 inches from about 3.6 ft) means placement has to be exact; cross-shopped with the TK710STi for builders who also game.

How it stacks up against the closest alternatives.
Who this is for
Honest match per persona.
Good for
- 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.
Not for
- Cost-Effective Buyer
$2,199 is upper-mid-tier money; Optoma's GT3900UHD is 4K laser at the same 0.496 throw for $700 less, and the GT2400HDR a budget answer at $1,299 if 4K is not essential.
- Recreational Player
Fixed throw with no zoom means inflexible placement; TK710STi or AH700ST are friendlier polished picks.
- Showroom
Brightness and feature set are mid-tier; LK936ST or AK700ST anchor showroom builds.

Room planner
See the Optoma UHZ35ST in your sim room.
The planner draws it to scale with your room and your screen: where it mounts, how far the lens sits from the screen, and whether your swing or your shadow crosses the light. It opens in a sample room; put in yours.
