It pairs 8.3 million pixels with a bright 4,100-lumen laser engine, rendering fairways, greens, and ball flight with sharp detail and natural color on screens up to 300 inches. Its sleek black chassis is designed to disappear into a simulator bay while delivering a vivid, true-to-life picture.\u003cbr\u003e\u003cbr\u003eA 0.496:1 short-throw lens lets the projector sit close to the impact screen, which reduces shadows and frees up usable hitting area in tight rooms. A dedicated Golf Sim color mode tunes blue skies, deep shadows, and grass-green tones for realistic courses, while Smart Fit uses your smartphone camera to detect the screen frame and automatically correct image alignment in seconds.\u003cbr\u003e\u003cbr\u003eThe DuraCore laser light source runs maintenance-free for up to 30,000 hours with instant on and off and no lamps to replace. Four-corner adjustment, plus or minus 15 degree keystone correction, dual HDMI 2.0 inputs, and low input lag down to 8.6 ms make it equally at home for golf simulation, gaming, and big-screen entertainment.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOptoma ZK431ST-B 4100-Lumens 4K UHD Short Throw Golf
