Description
The Optoma ZK521ST is a true 4K UHD DuraCore laser projector designed for golf simulators and commercial entertainment environments. Featuring a powerful 5,000-lumen laser light source and 8.3 million pixels, it delivers sharp, detailed visuals with vibrant fairways, greens, and ball flight on screens up to 300 inches. Its high brightness helps maintain clear images even in rooms with significant ambient light. The clean white chassis also blends naturally into light-colored ceilings and modern simulator spaces.
The 0.79:1 short-throw lens allows the projector to be positioned closer to the impact screen than standard-throw models, helping reduce shadows and minimize potential interference with clubs and golf balls. Custom aspect ratio support and geometric correction provide flexible image adjustments to fit different screen dimensions. A dedicated Golf Sim color mode enhances blue skies, deep shadows, and natural grass tones for a more realistic golf experience. Smart Fit uses your smartphone camera to detect the screen frame and automatically align the projected image in seconds.
Optoma's DuraCore laser technology provides up to 30,000 hours of maintenance-free operation, with instant power on and off and no traditional lamps to replace. With an input lag of just 8.6 ms at 1080p 120Hz, the ZK521ST delivers responsive performance for golf simulation and gaming. Dual HDMI 2.0 inputs and full network control add flexibility for commercial installations, gaming, and big-screen entertainment.
