Optoma Technology EH340UST 4000-Lumen Full HD Ultra-Short Throw DLP Projector

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.

DLP Technology

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.

Ultra-Short Throw Projection

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.

Computer-Free USB Image and Document Viewer

The built-in image and document viewer provides direct viewing of office documents, PDFs, images, and presentations from any compatible USB storage device.

RS-232 Control

Take control of the projector using HEX or ASCII commands via an RS-232 cable.

Four-Corner Adjustment

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.

Optional HDCast Pro for Wireless Display and Document Casting

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.

Additional Features

• LAN display via Ethernet with Windows and Mac OS X devices (up to four devices at once)
• Up-converts the 3D frame rate from 60 to 120 Hz or from 24 to 144 Hz to provide 60 or 72 frames per eye
