The Optoma EH340UST is an ultra short throw projector that utilizes DLP technology to produce a native 1920x1080 resolution. It has a brightness rating of 4000 ANSI lumens and a typical contrast ratio of 22000:1, making it functional in rooms with some ambient light. Its lamp-based light source provides a standard service life of 4000 hours, which extends to 10,000 hours in economic mode. The projector supports both 16:9 and 4:3 aspect ratios for compatibility with various source materials.

A primary feature of this projector is its 0.25:1 ultra-short throw ratio, which allows it to produce large images from a minimal distance. It is designed to project an 80 to 100-inch image when placed between 0.45 and 0.56 meters from the projection surface, making it suitable for installations in confined spaces. The unit offers placement flexibility with support for front, rear, and ceiling mounting configurations. Manual focus and ±4-degree keystone correction are available for image alignment.

For connectivity, the device includes two HDMI 1.4a ports, two VGA (D-Sub) ports, and two USB Type-A ports. An Ethernet LAN port enables network integration for management and control. The projector features a built-in 16-watt speaker for onboard audio, supports 1080p video modes, and can display 3D content from compatible sources. The package includes an AC power cable and a remote control for operation.
