Packed with user-friendly features, the EB-X11 is straightforward to set up and use, allowing you to focus on teaching. With equally high White and Colour Light output of 2,600 lumens, and 3 000:1 contrast ratio, you can achieve a bright, sharp image. Epson’s 3-in-1 USB Display feature means that one cable is all you need for picture, sound and page up/down control – it’s the fastest way to display what’s on your PC or Mac. Alternatively, using the PC-free feature, you can present still photos directly from a USB stick without powering up your computer.
