The PS501X is a high brightness XGA short throw projector for education. With the ability to project 100\" images from 124cm from any projection surface, the projector is flexible enough to fit any classroom design and keeps the presenter clear of the projection beam. For times when lights in the classroom must be kept on, a high brightness of 3, 500 ANSI Lumens ensures that images remain clear and detailed. View Sonic exclusive Super Color(TM) technology offers a true-to-life color accuracy for projected images. The energy-saving Super Eco mode reduces power consumption and extends lamp life to a lengthy 15, 000 hours. In addition, PS501X is compatible with the optional PJ-vTouch-10S interactive module, which allows you to use a stylus or finger touch to annotate on projected images - turning class into an engaging interactive teaching environment.
