Comparison
AH700ST vs TK710STi
Short answer
Same throw range, different priorities: the TK710STi is the cheaper true-4K projector, while the AH700ST spends its $2,299 on golf-room conveniences — motorized zoom, Auto Screen Fit, Golf Mode and a sealed 4,000-lumen engine — at 1080p.

By buyer
Which one for you
- Ceiling-mounted golf room, set it and forget it
- BenQ AH700ST. Motorized zoom and Auto Screen Fit mean adjustments without a ladder, plus a sealed engine.
- Want 4K for movies and gaming as well as golf
- BenQ TK710STi. True 4K at a lower price, if your PC can drive it.
- Sim PC built for 1080p
- BenQ AH700ST. More lumens and golf-specific features instead of resolution you can't use.

Bottom line
The longer answer
Both throw at 0.69–0.83, so both want roughly 7 ft or more from the screen for a 10-ft-wide image; room depth does not separate them. The AH700ST is $2,299. The TK710STi is $1,999 at Amazon, where BenQ's own store sells it, and $2,199 at the golf retailers, so the gap runs from $100 to $300.
The AH700ST is built for a golf room you set up once and leave. Its 1.2x zoom is motorized and a front camera handles Auto Screen Fit, so squaring the image to an impact screen does not mean a ladder. It has a Golf Mode color preset, BenQ's IP5X-sealed laser engine, 4,000 ANSI lumens, and 16.7 ms input lag at 1080p/120Hz (33.4 ms at 60Hz). Its limit is resolution: 1080p.
The TK710STi is the generalist. True 4K with HDR10 and HLG, 3,200 ANSI lumens, and 4.2 ms input lag at 1080p/240Hz make it the better movie and gaming display. Zoom and focus are manual, and there is no Golf Mode or sealed engine; BenQ rates its fan at 31 dB, or 28 dB in eco mode.
The deciding question is usually the PC. 4K golf needs a graphics card that can drive it smoothly; if yours cannot, the TK710STi's headline feature goes unused and the AH700ST is the smarter mid-tier buy.
