The EH330UST, is perfect for businesses, schools and colleges. It is bright with an ultra short throw meaning it can project a 100” image from less than 0.5m away. And having the projector installed so close to the wall 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, native office viewer and powerful 16W built-in speaker.
