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.

Long Lamp Life

Reduce the number of lamp changes with long lamp life.

Amazing Color

Optoma 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.

Dynamic Black Technology

This feature gives more depth to your image by smoothly adjusting the lamp output to create a stunning high contrast ratio. Bright scenes appear crisp and clear, while dark scenes remain detailed with deep blacks and exceptional light and shade detail.

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.

Signal Power On

The projector powers on when it receives a signal through the HDMI input. This ensures the projector is turned on at the same time as the source device.

MHL Connectivity

Turn your projector into a smart display by connecting your smartphone or tablet with a single cable using MHL; now you can view presentations and documents, stream videos and share photos on the big screen.

RS-232 Control

Take control of the projector using HEX or ASCII commands via RS-232 cable.

USB Power

Power and charge your USB devices with the USB power port. The port delivers up to 1-amp and ideal for some HDMI streaming sticks.
