Comparison

TK710STi vs UHZ35ST

Short answer

The BenQ TK710STi at $1,999 is the cheaper buy now that B&H's $1,499 clearance on the Optoma UHZ35ST has sold out: the Optoma is $2,199 at Amazon, Optoma's list. The UHZ35ST is still the better-specified golf projector — brighter, a shorter fixed throw, a sealed engine and a Golf Sim mode — but it costs $200 more, while the BenQ has a zoom lens and is a current model.

By buyer

Which one for you

Most buyers
BenQ TK710STi at $1,999 on Amazon. $200 less than the Optoma and a current model.
Dusty garage, or the projector must sit close to the screen
Optoma UHZ35ST at $2,199. Brighter, IP6X-sealed, a 5-ft throw for a 10-ft image and a Golf Sim mode, for $200 more.
Mount position not settled yet
BenQ TK710STi. Its zoom gives about 1.4 ft of mounting latitude for a 10-ft image; the Optoma's fixed throw gives none.

Bottom line

The longer answer

Price first, because it moves the answer. The TK710STi is the laser successor to BenQ's discontinued TK700STi. It is $1,999 at Amazon, where BenQ's own store holds the listing, and $2,199 at the golf retailers we track. The UHZ35ST was $1,499 on clearance at B&H in the fall of 2026; as of November B&H lists it as discontinued with back-order only, Indoor Golf Outlet no longer carries it, Newegg is out of stock, and Amazon sells it at Optoma's $2,199 list.

Both are 4K UHD laser short-throws with HDR10 and HLG and nearly identical gaming lag: about 4 ms at 1080p/240Hz and 16 to 16.7 ms at 4K/60Hz on each maker's spec sheet. The Optoma is brighter, 3,500 lumens on its sheet against BenQ's 3,200 ANSI, rates its laser for 30,000 hours against BenQ's 20,000, has an IP6X dust-sealed engine and includes a Golf Sim picture mode. The BenQ adds a 1.2x manual zoom and an Android TV dongle.

Throw is the bigger practical difference. The UHZ35ST's fixed 0.496 ratio fills a 10-ft-wide image from about 5 ft, so it can sit well in front of the hitting area, but with no zoom the mount has to be measured exactly. The TK710STi's 0.69–0.83 zoom needs about 7 to 8.3 ft for the same image and gives you that much latitude in where the mount goes.

At $2,199 the Optoma's extra light, sealed engine and Golf Sim mode cost $200 more than the TK710STi, which is BenQ's current model. Pay it if the room is dusty, the image needs every lumen, or the mount has to sit close to the screen; otherwise the TK710STi is the better buy. If you want the Optoma's fixed 0.496 throw in 4K for less, Optoma's own GT3900UHD is $1,499. Either way, make sure your sim PC can drive 4K before paying for it.

Better for TK710STi

  • Recreational Player

    True 4K with laser life and HDR — the courses look genuinely impressive and the projector lasts the life of the room.

Better for UHZ35ST

  • 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.
