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.

Full 3D

Display true 3D content from almost any 3D source, including 3D Blu-ray Disc™ players, 3D broadcasting, and the latest-generation game consoles. Support for 144Hz rapid-refresh rate provides ultra-smooth flicker-free images. DLP Link 3D glasses required.

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.


Using sophisticated frame-interpolation technology, advanced motion control processing eliminates motion blurring or image judder, even in high-speed action sequences. PureMotion works in 2D and is optimized for 1080p24.


This technology ensures all the information contained in an image is accurately reproduced on the screen to give a stunning crystal clear, pin-sharp picture. Complex algorithms detect each frame and improve image sharpness before the frame is projected.


This mode allows the projector to reproduce more detailed shades of color for vibrant, natural-looking images. Colors are more saturated and more accurate.


High dynamic range (HDR) technology delivers brighter whites and deeper black levels. Optoma HDR accepts HDR10 signals with four selectable picture modes: Normal, Bright, Detail, and Film.


Color the way it is meant to be seen – rich, colorful and cinematic pictures and games via DCI-P3 wide color gamut coverage.


HDR signals are mapped using REC.2020 tone mapping and provides coverage for REC.709, DCI-P3 and a wide coverage color gamut.

PC-Free USB 4K UHD HDR Media Player

Integrated 4K UHD HDR USB Media Player provides playback of 1080p and 4K UHD HDR video, audio files and images along with support for Office Documents and PDF Files.
