BENQ AK900ST SHORT THROW LASER GOLF SIMULATOR PROJECTOR - 6000 LUMENS

*New: October 2026

• World's First AI Golf Projector: AI Sim Sense visuals and setup.
• Built for Grand Spaces: 4K 6000lm Golf Mode color and optical lens shift.
• Auto Screen Fit 2.0: One-press curved and flat screen alignment.

The BenQ AK900ST is a high-performance 4K laser projector designed for premium residential and commercial golf simulator installations. Delivering 6,000 ANSI lumens, true 4K UHD resolution and golf-specific image processing, it produces a bright, highly detailed image suitable for large impact screens and rooms with higher ambient light.

BenQ’s AI Sim Sense technology enhances golf simulator content using dedicated AI processing. It improves contrast, sharpness, colour and fine course details while reducing noise and unwanted visual artifacts.

Installation is simplified through Auto Golf Screen Fit 2.0, motorized autofocus and automatic ambient-light adjustment. The built-in camera detects the shape and dimensions of the impact screen—including flat and curved configurations—and automatically fits the image to the screen.

The AK900ST also includes substantial vertical and horizontal lens shift, providing added flexibility when the projector cannot be installed directly in line with the centre of the screen. This is particularly useful in commercial facilities, multipurpose rooms and simulator installations involving launch monitors or other ceiling-mounted equipment.

With its 6,000-lumen output, flexible lens controls and dedicated Golf, Bright Golf and HDR Golf modes, the AK900ST is positioned for simulator rooms where image brightness, installation flexibility and premium 4K performance are priorities.
