Why This Product
Pro-grade, piece by piece
True 4K Laser Clarity
The BenQ LK830ST delivers true 4K UHD resolution (3840×2160) — 8.3 million pixels of razor-sharp course detail — driven by a bright, long-life laser engine built for serious golf simulator setups.
4,000 Lumens for Bright Rooms
At 4,000 ANSI lumens, the LK830ST stays vivid and high-contrast even in rooms with ambient light — no need to play in total darkness to get a premium image.
Ultra-Short Throw + Golf Mode
An ultra-short 0.5 throw ratio mounts the projector close to the screen for space-efficient, shadow-free installs, while a dedicated Golf Mode renders realistic course color and terrain.
20,000-Hour Laser Engine
The laser light source runs up to 20,000 hours with consistent brightness and color — effectively maintenance-free for the life of most simulator setups, with no lamp changes.

What Golfers Say About the BenQ LK830ST
The LK830ST is BenQ’s newest golf-sim projector — expert reviews below; owner reviews will be added as they land.
4.6
★★★★★
The greens of the course and the blues of the sky don’t appear neon, and the textures are excellent. At 4,000 ANSI Lumens, the LK830ST is bright and designed to overcome uncontrolled ambient light sources.
★★★★★
The only 4K projector at this throw ratio. Floor mounts, enclosure mounts, and short rooms — the LK830ST installs where other projectors can’t. On screens 120 inches and larger the 4K difference is clearly visible in course textures, yardage markers, and fairway detail.
★★★★★
If your room depth is under 16 feet, the LK830ST is likely the only 4K projector that will work for you. The 0.496 throw ratio fills a 10-foot screen from 4.3 feet.
