DLP Technology

DLP® (Digital Light Processing) is a proprietary technology from Texas Instruments that offers digital projection with higher contrast, faster response time, good pixel structure and virtually no color degradation.

3D Ready

Optoma 3D Ready projectors can output video and images at an astonishing rate of 120Hz, allowing you to show full-screen, full-color, stereoscopic 3D. Optoma 3D glasses required.

HD Ready

HD Ready resolution (720p) renders sharp and detailed images from HD content without downscaling or compression, which is perfect for watching movies, TV shows and gaming.

Short Throw Projection

Project images in limited space environments with short-throw projection. The short-throw lens requires short distances to project large images.

Quick Resume

This feature allows the projector to be instantly powered on again within 100 seconds of turning it off.

PC-free USB Image and Document Viewer

Integrated PC-free image and document viewer provide direct viewing of office documents, PDFs, images and presentations from any USB storage device.

Color Matching System (CMS)

The full HSG color matching system enables hue, saturation and gain adjustments for each primary color to match user preferences. This creates seamless blends every time when combined with accurate measurements.

Amazing Color

Our projectors are capable of reproducing the Rec.709 color gamut, the international HDTV standard, to guarantee accurate reproduction of cinematic color exactly as the director intended. Our projectors can also create saturated colors, great for gaming and animated movies.

Direct Power On

Turn on the projector directly from the power source. This feature aids installations that rely on power-on timers. The sleep timer can be used to turn the projector off after a set time.

24/7 Operation

Optoma projectors are engineered to operate 24 hours a day in standard orientation and perfect for applications that require prolonged periods of use (subject to 24-hour terms and conditions).
