    Overview<\/strong><\/span><\/h2>\n

    The LSD400HD-ST is a bright, short-throw laser projector built for classrooms, meeting rooms, and immersive setups where space is tight. With 4,000 ANSI Lumens<\/strong> and 1080p<\/strong> resolution, it delivers sharp, vibrant images even with ambient light. Its 0.5:1 throw<\/strong> produces a 100\u2033 screen from about 1.1 m<\/strong>, minimizing shadows and glare. The laser-phosphor engine provides up to 30,000 hours<\/strong> of virtually maintenance-free operation. Setup is fast and precise with H\/V keystone<\/strong>, 4-corner correction<\/strong>, 360\u00b0 projection<\/strong>, and a dust-sealed optical engine<\/strong>. Network control via LAN\/RS-232<\/strong> fits neatly into managed AV environments.<\/span><\/p>\n
