Optoma EH412x Full HD 1080p Projector – 4500 Lumens, HDR Compatible, 1.3x Zoom, 15,000-Hour Lamp Life

The Optoma EH412x is a 4,500-lumen Full HD DLP projector for presentations, teaching, and general-purpose viewing in bright rooms. It accepts HDR and 4K sources over HDMI 2.0, includes a 1.3x zoom and 10W speaker, and runs as quietly as 26dB in Eco mode.

Deep-Dive Story & Problem/Solution

Projector Fan Noise and Dim Images Distract From the Presentation

In a small or mid-size room the projector often sits above the table. If its fan is loud, it competes with speakers and conference call audio. If it is dim, the lights go off and the session loses energy.

The EH412x combines high output with restrained noise. A 240W lamp produces 4,500 ANSI lumens while the cooling system holds 28dB in normal mode and 26dB in Eco. Power consumption is about 285W.

Native 1920 x 1080 resolution and a 22,000:1 contrast ratio keep fine text readable. The HDMI 2.0 input accepts HDR and 4K signals, so presenters can plug in without adjusting display settings.

High Brightness With Full HD Detail

The projector supports images from about 31 to 301 inches, wide enough for huddle rooms through to lecture spaces. Full HD 3D playback is available.

Quiet, Portable, and Economical

At 7.3 lbs it is easy to carry or mount. Lamp life extends to 15,000 hours in Eco mode, and the filter-free DLP engine avoids regular filter cleaning.
