BenQ TK700STi vs Optoma GT3900UHD Short Throw Projector

The Optoma GT3900UHD is the stronger pick for most people: a laser light source rated to 30,000 hours, 4,000 lumens, a 0.49:1 throw that fills a wall from about 3.6 ft, and 4.3 ms input lag at 1080p/240Hz. The BenQ TK700STi is a lamp projector at 3,000 lumens with a 0.9–1.08:1 throw, so it needs more distance for the same image and its lamp will dim and need replacing. The BenQ ships with an Android TV adapter and a 3-year warranty and is easier to fit in a normal room; the Optoma wins on brightness, light-source life, gaming lag and golf-sim tuning.

• Choose the BenQ TK700STi if you want a bundled streaming stick, a longer warranty and a throw distance that suits a shelf or ceiling mount in a typical living room.
• Choose the Optoma GT3900UHD if you want laser life, more brightness for a lit room, the shortest throw, or low-lag gaming and golf simulation.
