Epson PowerLite 520 3LCD Projector - V11H674020 The Epson PowerLite 520 3LCD Projector is ideal for classroom settings, rear projection, and other installations where the projector needs to be placed very close to the screen. For example, with a 28" throw distance, it will produce a 106"-diagonal image. The 3LCD imaging device features an XGA (1024 x 768) native resolution, and is backed up by a lamp producing a brightness of 2700 lumens in its brightest setting. In addition to XGA, the projector can scale a range of non-native resolutions from SD (480p) up to UXGA (1600 x 1200). 2700 Lumens XGA Resolution Short Throw Technology What our Experts Think Bright and versatile: Approximately 3,000 lumens of color and white brightness make it suitable for classrooms, meeting rooms, and moderately lit environments.
