Designed for short-throw projectors, the 25941 IDEA 59.5 x 95.25" Whiteboard Screen from Da-Lite is designed to cover the wall of a classroom, is hotspot-free under projection, and is magnetic. It can be used with an ultra-short throw projector as an interactive screen or as a conventional whiteboard with dry-erase markers. A 24" tray for markers makes the IDEA an ideal upgrade to any classroom.
