BenQ AK900ST – 6000-Lumen 4K Laser Projector Built for Golf Simulators
The BenQ AK900ST is BenQ's flagship 4K short throw laser golf simulator projector. It combines 6,000 ANSI lumens, true 4K UHD (3840 × 2160) resolution, AI-driven Golf Mode 2.0 and a camera-assisted setup system, giving home simulators, garage bays and commercial golf studios a sharp, true-to-life picture with far less installation work.
True 4K Detail You Can Read on Every Shot
With 8.3 million addressable pixels, the AK900ST resolves the fine detail that makes a virtual round feel real: turf texture on the tee box, mowing stripes down the fairway and the subtle contours around the green. Every hazard and landing area looks the way it does on the course.
AI Golf Mode 2.0 with 97% Rec. 709 Colour
BenQ's second-generation AI Golf Mode uses a dedicated video processor to tune every frame in real time. Paired with 97% Rec. 709 colour coverage and a 3,000,000:1 contrast ratio, it keeps fairways natural, skies clean and the pin easy to pick out from any tee box.
6,000 Lumens for Bright Rooms and Commercial Bays
At 6,000 lumens, the AK900ST holds colour and contrast with the lights on. That makes it a strong fit for garages, finished basements, simulator lounges and indoor golf facilities where full blackout isn't practical. Its built-in camera also powers an Ambient Light Enhancer that monitors room light and adjusts colour and saturation automatically.
AI-Powered Setup: Auto Screen Fit 2.0, Smart Warping and Autofocus
-
Auto Screen Fit 2.0: the built-in camera detects your impact screen's shape, size and curvature, then aligns a distortion-free image in seconds on flat or curved screens.
-
Smart Warping: after the first alignment, progressively added control points make fine-tuning curved screens fast and intuitive.
-
Motorized autofocus and 1.1x motorized zoom: adjust sharpness and image size from the remote, with no ladder and no repositioning.
-
Screen Fill for golf screens: native output for 16:9, 16:10, 3:2, 4:3, 5:4 and 1:1 screens without stretching or black bars.
4-Way Optical Lens Shift for Any Mounting Position
Optical lens shift of ±60% vertical and ±23% horizontal lets you mount the AK900ST high, low or off-centre while keeping full optical 4K quality, with no digital keystone softening. It's easier to keep the projector out of the swing path and free of shadows, whatever your ceiling height or bracket location.
Short Throw Lens Designed for Golf Simulation
A 0.81–0.89 throw ratio fills a 10-ft-wide (16:9) image from roughly 2.5–2.7 m (8.1–8.9 ft), so the AK900ST can be mounted overhead and clear of the hitting area in typical simulator rooms.
Simulator by Day, Home Theatre by Night
Golf Scene Memory saves up to five complete display profiles (picture mode, screen fill, zoom, focus, geometry, audio and input source), so switching from a simulator session to movie or game night takes one button. Input lag as low as 4.8 ms at 1080p/240 Hz (18.1 ms at 4K/60 Hz), HDR10 and HLG support, and HDMI eARC audio round out the entertainment experience.
