BenQ LK830ST vs BenQ AK700ST

Both are 4,000-lumen 4K laser short-throw projectors from BenQ, so the choice comes down to throw distance and installation. The LK830ST throws a bigger image from closer (0.5:1 fixed lens), runs at up to 240 Hz with 16.7 ms input lag, and supports 360-degree mounting, which suits simulators, museums and multi-projector rigs. The AK700ST has a 1.2x zoom (0.69–0.83:1), Auto Screen Fit, Golf Mode and USB-C, and is the easier drop-in for a golf bay or home theater. Owners of both praise brightness and 4K sharpness; the LK830ST's common gripe is its external power brick, and one AK700ST owner found setup hard.

• Choose the BenQ LK830ST if you need the shortest throw, high frame rates for simulation, or 360-degree and portrait mounting.
• Choose the BenQ AK700ST if you want a zoom lens, automatic screen fitting and Golf Mode presets for a golf bay or home theater.
