BenQ AK900ST – 6,000-Lumen 4K Laser Golf Simulator Projector
The BenQ AK900ST is a 4K UHD short throw laser projector designed for golf simulator rooms. Its 6,000 ANSI lumens, golf picture modes and flexible optical adjustments help create a detailed, bright image for home practice and larger indoor installations.
4K golf projection with easier setup
- Detailed course visuals: 3840 × 2160 resolution, 97% Rec.709 coverage and BenQ Golf Mode 2.0 support natural-looking course colours.
- AI Sim Sense: dedicated image processing enhances golf visuals, while the integrated camera supports automatic screen fitting and adjustment to ambient light.
- Motorised zoom and autofocus: adjust the image from the remote control instead of reaching the projector.
- Flexible positioning: a 0.81–0.89 throw ratio, 1.1× zoom and generous lens shift help adapt the installation to your screen.
- Beyond golf: HDR10/HLG support, cinema and gaming picture modes, plus HDMI eARC, let the same room serve other entertainment uses.
Will the AK900ST fit your simulator?
For a 4-metre-wide 16:9 image, the 0.81–0.89 throw ratio gives a theoretical lens-to-screen distance of approximately 3.24–3.56 metres. This calculation uses image width, not room depth. Allow space for the projector body, cables, ventilation and a clear swing path.
The AK900ST offers vertical lens shift of ±60% and horizontal lens shift of ±23%. Its Screen Fill settings include 16:9, 16:10, 3:2, 4:3, 5:4 and 1:1. Changing the image format or using digital correction can change the usable image area. Automatic screen fitting also has installation requirements; confirm the final position against BenQ's projection guidance before mounting.
