The catch
BenQ TK700ST
Owning it still includes lamp upkeep and separate streaming equipment.
Side by side
BenQ TK700ST vs BenQ TK710STi: Their 120-inch positions differ, though both are short throw
Quick verdict
The TK710STi brings laser illumination and included Android TV, provided its shorter lens fits. The TK700ST is for an existing mount around eight to nine feet away that has to fill a 120-inch screen. Both are short throw, yet their optical intervals at 120 inches never overlap.
Before you buy
Why, and what it costs you
Going to laser could mean relocating the mount
With TK700ST, a lens position of eight feet frames 120 inches. For that image TK710STi’s maximum distance is about 7.2 feet, so keeping the old mount would take another screen size or digital reduction. Price the mounting work before you decide.
Where this comes from
BenQ TK700ST: 0.9 to 1.08 gives 7.84 to 9.41 ft. BenQ TK710STi: 0.69 to 0.83 gives 6.01 to 7.23 ft.
The catch
BenQ TK710STi
At your current screen size, the shorter lens can make an existing short-throw mount unusable.

How we worked this out
BenQ TK700ST: 0.9 to 1.08 gives 7.84 to 9.41 ft. BenQ TK710STi: 0.69 to 0.83 gives 6.01 to 7.23 ft.
With nightly use, maintenance counts for more than the lumen gap
Routine lamp replacement drops out of the plan with TK710STi. Its output rating is only about 7 percent higher, and neither value establishes calibrated output. Frequent evening viewing is a clearer reason to prefer laser than hoping for a dramatic jump in brightness.
How we worked this out
BenQ TK700ST: Lamp source, 3,000 ANSI-lumen rating. BenQ TK710STi: Laser source, 3,200 ANSI-lumen rating. Difference 6.67 percent.
The STi suffix changes what goes in the cart
Android TV comes with TK710STi, whereas this exact TK700ST needs an external source. If it is your first projector, compare the total with a streamer and its connections included. In a room already run through a receiver, that advantage counts for less.
How we worked this out
BenQ TK700ST: Exact TK700ST package has no included streamer. BenQ TK710STi: Exact TK710STi includes Android TV.
