Description
The Optoma ZK431ST is a true 4K UHD DuraCore laser projector designed to meet the demands of indoor golf simulation. Featuring 8.3 million pixels and a bright 4,100-lumen laser light source, it delivers sharp details and natural colors across fairways, greens, and ball flight on screens up to 300 inches. Its sleek white chassis blends seamlessly with light-colored ceilings and interiors while producing bright, lifelike visuals.
The 0.496:1 short-throw lens allows the projector to be positioned close to the impact screen, helping reduce shadows and maximize usable hitting space in compact simulator rooms.
