BenQ TK710STi vs Optoma GT2400HDR: Which Projector

Updated September 2026

The BenQ TK710STi and Optoma GT2400HDR both fill a golf simulator screen from a short room depth, but they solve different problems. The TK710STi is a true 4K laser projector built for image quality. The GT2400HDR is a 1080p ultra short throw unit with a tighter 0.496:1 ratio for very compact rooms.

Which should you buy?

Buy the BenQ TK710STi if true 4K image quality and Golf Mode color calibration matter most and your room has 7 to 9 feet of throw distance to work with. Buy the Optoma GT2400HDR if your room is tight enough that you need the 0.496:1 ultra short throw ratio to fill a 12-foot screen from under 6 feet, and 1080p resolution with 4,200 lumens is an acceptable trade for that placement flexibility. Run the throw ratio math for your own room depth before choosing either.

Common questions

Which projector fits a shorter room?

The Optoma GT2400HDR, by a wide margin. Its 0.496:1 throw ratio fills a 12-foot screen from under 6 feet of throw distance, while the BenQ TK710STi's 0.69 to 0.83:1 ratio needs roughly 7 to 9 feet to fill the same size screen.

Is 4K worth it over 1080p for a golf simulator screen?

It depends on screen size and viewing distance. The BenQ TK710STi's true 4K laser image shows more detail on larger screens viewed from close range. The Optoma GT2400HDR compensates for its 1080p resolution with 4,200 lumens of brightness, which matters more than resolution in rooms with ambient light from garage doors or windows.

Which projector is easier to set up?

Neither is fully automatic. The BenQ TK710STi requires manual zoom and focus adjustment during installation. The Optoma GT2400HDR's ultra short throw design requires a specific ceiling mount position directly above the screen, which is less forgiving of measurement error during planning.

Do both have Golf Mode color calibration?

Golf Mode color calibration is a BenQ TK710STi feature built specifically for simulator screens. The Optoma GT2400HDR does not list a golf-specific color mode in its published specifications, so image tuning on that unit relies on its general HDR and lumen output instead.
