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.
DLP (Digital Light Processing) is a Texas Instruments technology designed to provide high contrast, fast response time, enhanced pixel structure, and virtually no color degradation.
Project large images in limited spaces with the short 0.25:1 throw ratio, limiting or eliminating shadows cast by the presenter. This makes the EH340UST well suited for use in interactive and educational applications.
The built-in image and document viewer provides direct viewing of office documents, PDFs, images, and presentations from any compatible USB storage device.
Take control of the projector using HEX or ASCII commands via an RS-232 cable.
Four-corner geometric correction enables quick and easy image adjustments from any of the corner points of the image, simplifying projection on uneven or angled projection surfaces.
Mirror your Android, Windows, or Mac device wirelessly, cast images from Android, iOS, Windows, and Mac devices, or use USB Display to mirror your Android or iOS screen.
