1080P ultra short throw projector for business and education

The Optoma EH320UST is the market’s first 1080p ultra short throw DLP® projector. It is Optoma’s feature-packed next generation ultra short throw projector for business and education users that demand bright 1080p projection.

The impressive ultra-bright 4000 lumens, 20,000:1 contrast ratio and powerful 16-watt speaker delivers stunning image quality and crisp audio. Its industry-leading throw ratio of 0.25 projects a 100-inch image from only 22 inches away.

Flexible and robust connectivity provide full network control support, including Crestron, PJ Link, RS-232C and Telnet-based protocols, for simple integration with existing and new installations. Up to 6500 hours of lamp life ensures reliability with low-maintenance.

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.

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. Optoma 3D glasses required.

High Contrast

Add more depth to your image with a high-contrast projector. With brighter whites and ultra-rich blacks, images come alive and text is crisp and clear.


Specially designed lamp modes reduce power consumption by up to 70%. Each mode also improves lamp life, which lowers the total cost of ownership and reduces maintenance.

Quick Resume

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

AV Mute

When enabled via remote control or network management, the projector suspends (dims) video output to conserve energy.

Auto Power Off

To help save energy, this feature automatically turns off the projector after a set period of time, if it is not being used.

Full HD 1080p

1080p (1920×1080) resolution renders sharp and detailed images from HD content without downscaling or compression, which is perfect for movies, TV shows and gaming.

Ultra Short Throw

Ultra short throw projection enables closer placement to the wall with reduced shadows for easy presenting. The placement makes it perfect for interactive applications and education environments, too.

Wireless Presenting (optional extra)

Making presentations couldn’t be easier using the optional wireless features of the WPS Wireless Adapter (sold separately) – you can connect and display presentations wirelessly from a laptop, PC or mobile device.
