Engineered for Space-Saving Golf Simulation

The Optoma ZK431ST 4K Short Throw Laser Projector is purpose-built for compact indoor golf simulator bays. Combining 4,100 lumens of brightness with a dedicated 0.496:1 short-throw lens, it allows you to fill a massive impact screen from less than two metres away. This keeps the projector safely out of your swing path, prevents you from casting shadows onto the virtual fairway, and frees up valuable overhead space.

Advanced Hardware Performance

Dedicated Golf Sim Picture Mode: Pre-calibrated to deliver true-to-life greens and blues, ensuring your virtual courses look vibrant even with overhead tracking lights turned on.
Responsive Simulator Speed: Experience ultra-low input lag (16.7ms at 4K 60Hz and 8.6ms at 1080p 120Hz), ensuring real-time ball flight rendering from TrackMan, GSPro, and FSX Play.
DuraCore Laser Engine: An IP6X-certified sealed optical assembly provides up to 30,000 hours of consistent, maintenance-free illumination without the need for expensive lamp replacements.
Flexible Geometry Adjustment: Features 4-corner adjustment and vertical/horizontal keystone correction (±15°) to help you easily achieve a perfectly square image on your impact screen.

Frequently Asked Questions

Is the Optoma ZK431ST bright enough for a room with ambient light?

Yes. With 4,100 ANSI lumens, this projector handles moderate ambient lighting very well. It is perfectly suited for golf simulator studios that require overhead downlights or spotlights for launch monitor tracking cameras.

Do you offer turnkey installation for this projector?

No. Golf Sim Solutions is strictly a supply-only business. We specialize in providing the highest quality hardware directly to you with fast UK shipping, but we do not carry out physical installations or room fit-outs.

How far away does the ZK431ST need to be mounted?

Due to the ultra-short 0.496:1 throw ratio, you can project a massive image from very close range. Depending on your exact impact screen size, it typically sits between 1.2m and 2.5m away from the screen, keeping it safely in front of the golfer’s swing path.
