BenQ AK800ST 5,000 ANSI Lumens 4K Laser Short Throw Projector

BenQ AK800ST – 4K Laser Short Throw Golf Simulator Projector

The BenQ AK800ST is a 5,000 ANSI lumen 4K UHD laser projector designed for golf simulators. Its short throw zoom lens lets it hang out of the swing zone and still fill large impact screens, and its colour modes make fairways and skies look natural.

Setup is helped by motorised zoom and focus, camera-assisted Auto Screen Fit 2.0 for flat and curved screens, and Scene Memory for switching between golf, films and gaming. That makes it a good choice for home simulator rooms and commercial golf venues.

Picture Quality

A laser DLP engine delivers 4K UHD (3840 x 2160) images with 97% Rec.709 colour and a 3,000,000:1 contrast ratio. Golf-specific modes boost greens and skies, and a built-in camera can read the ambient light and recalibrate colour, so courses look right in the dark or in daylight.

Installation and Throw

The short throw lens (0.69-0.83) with 1.2x motorised zoom lets you mount the projector out of the swing zone. A 100-inch 16:9 image needs roughly 1.5-1.8 m (calculated from the throw ratio), and BenQ quotes a 300-inch 4K image from just 4.6 m. Screen Fill and six native EDID aspect ratios (16:9, 16:10, 3:2, 4:3, 5:4 and 1:1) match common simulator screens without stretching. Scene Memory stores up to five complete display profiles.

Connectivity

Three HDMI 2.1 inputs (HDCP 2.3) include eARC with 7.1-channel passthrough and ALLM, alongside two USB-A ports, RJ45 LAN, RS232 and a 3.5 mm audio output. Wireless projection (iOS mirroring, Google Cast and Miracast) is listed, using the optional EZC-5201BS dongle.
