Optoma EH320UST

Optoma’s 1080p ultra short throw projector, the EH320UST, is perfect for businesses, schools and colleges. It is bright (4,000 lumen) and a throw ratio of 0.25:1 means that it can project a 100” diagonal image from just 22" away. And having the projector installed so close to the screen avoids any shadows being cast across the screen from the presenter(s).
It provides a complete package for engaging learning with many new features, including two HDMI inputs, powered USB port, powerful 16W built-in speaker, improved lamp life, compact chassis and a completely new mounting system for a fast and simple set-up.

  • Full HD 1080p resolution, 20,000:1 contrast ratio

    Comments about Optoma EH320UST:

    Though I've not used it much yet, I set it up to check it out. I needed something that would work in a high ambient light situation. My initial tests seem to be very positive. It had an excellent, clear picture with plenty of ambient light all around. Within just a foot of the screen I was able to get about a 60" angle viewing area. I feel this projector will serve us well.
