The Optoma EH412 is a Full HD 1080p DLP professional projector built for business environments where reliable, high-quality projection in ambient light is essential. Delivering 4,500 lumens of brightness, it is designed specifically for well-lit meeting rooms, conference rooms, training facilities, and classrooms without requiring a darkened space. Its 4K HDR input capability paired with a 50,000:1 dynamic contrast ratio and sRGB/Rec. 709 color accuracy ensures vivid, true-to-source image quality whether connected to a laptop, 4K video source, or presentation PC. A 1.3x manual zoom and ±40° vertical keystone correction allow flexible installation across a wide range of room layouts, while the comprehensive connectivity suite — HDMI 2.0, HDMI 1.4a, VGA in/out, audio in/out, RS232, and USB-A — integrates cleanly into any AV setup. With a built-in 10W speaker and a lamp life of up to 15,000 hours in Eco+ mode, the EH412 reduces setup complexity and long-term maintenance costs for organizations deploying across multiple rooms or buildings.
