Product Overview
Optoma Technology EH340UST Overview
Enjoy bright, clear images at short throw distances with the Optoma EH340UST 4000-Lumen Full HD Ultra-Short Throw DLP Projector. Its 4000 lumens of brightness will overcome ambient light in many settings, while its 20,000:1 dynamic contrast ratio and Full HD 1920 x 1080 native resolution will help ensure that detail is clear. It has an ultra-short 0.25:1 throw ratio, which will allow you to place the projector just a few inches from your screen or wall to prevent the casting of shadows by people walking in front of it.
The EH340UST has a VGA and two HDMI inputs to support a variety of devices; a VGA output allows you to daisy-chain the image to another projector or display, while the analog audio input and output will do the same for your audio. It has a built-in 16-watt speaker to eliminate the need for a separate speaker system. It is controllable via Ethernet, RS-232, or the included IR remote control.
