Optoma's 1080p ultra short throw projector, the EH319UST, is perfect for businesses, schools and colleges. It is bright and a throw ratio of 0.25:1 means that it can project a 100" image from just 55cm away. And having the projector installed so close to the screen avoids any shadows being cast across the screen from the presenter.
It provides a complete package for engaging learning with many features, including two HDMI inputs, powered USB port, powerful 16 W built-in speaker, improved lamp life, compact chassis and a completely mounting system for a fast and simple set-up.
With an ultra-short throw lens, you can project an impressive image greater than 100" from just 55 cm away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease; perfect for interactive applications.
Full HD 1080p
1080p resolution gives you sharp and detailed images from HD content without downscaling or compression; perfect for watching Blu-ray movies, HD broadcasting and playing video games.
Add more depth to your image with a high contrast projector; with brighter whites and ultra-rich blacks, images come alive and text appears crisp and clear - ideal for business and education applications.
Optoma projectors can display true 3D content from almost any 3D source, including 3D Blu-ray players, 3D broadcasting and the latest generation games consoles. Support for 144 Hz rapid refresh rate provides ultra-smooth flicker free images.
The built-in speaker offers excellent audio support. Easy to set up without the need for costly external speakers.
Eco+ technology brings together high contrast, improved lamp life and energy saving features that are easy to use while reducing power consumption.
Using the specially designed lamp modes, you can reduce the power consumption by up to 70%. Each mode also has a positive effect on the lamp life, while lowering the total cost of ownership and reducing maintenance.
This feature allows the projector to be instantly powered on again, if it is accidentally switched off.
Auto power off
There may be instances when the projector is left running when not in use. To help save energy, the "auto power off" feature automatically turns off the projector after a set period of time if it is not being used.
Eco AV mute
Stay in control of your presentation with Eco AV mute. Direct your audience's attention away from the screen by blanking the image when no longer needed. This also reduces the power consumption by up to 70%, further prolonging the life of your lamp.
Keep your audience's attention focused on the right things using the simple, yet powerful remote with USB mouse control.
Networking and control
Featuring a wide range of options you can remotely control and monitor the projector.
