Optoma GT3900UHD Short Throw Projector vs BenQ TK700ST 4K Short Throw Projector
The Optoma GT3900UHD is the stronger pick for most people comparing these two. It is brighter at 4,000 lumens versus 3,000, throws a bigger image from closer (0.49:1 versus roughly 0.9:1), and its laser light source is rated to 30,000 hours against a lamp in the BenQ. The BenQ TK700ST counters with HDR10 support, a 1.2x optical zoom and 2D keystone for easier placement, and slightly lower lag at 4.2ms in its fastest mode. Owners of short-throw gaming projectors consistently rate laser life and brightness above lamp convenience, so the Optoma wins on longevity and light-room performance while the BenQ wins on setup flexibility and HDR.
- Choose the Optoma GT3900UHD if you want the brightest picture, a very short throw for a small room, laser life without lamp swaps, or a golf sim mode.
- Choose the BenQ TK700ST if you need HDR10, optical zoom and auto keystone for flexible placement, and play competitive games where the lowest lag matters.
