Enjoy virtually shadowless images in most installations with the Maxell MC-AW3506 3700-Lumen WXGA Ultra-Short Throw 3LCD Projector. It features an ultra-short 0.3:1 throw ratio (measured from the mirror cover), which allows it to be mounted directly above or below your screen, wall, or whiteboard to project an image as large as 100″, reducing the risk of possible shadows. Its 3700 lumens of brightness, combined with its 20,000:1 dynamic contrast ratio, helps it overcome ambient light in many situations and retain detail in dark areas of the image without compromising overall brightness.
