With 5000 ISO lumens and a contrast ratio of 3000:1 the XGA-resolution Epson PowerLite 1960 Multimedia Projector has the projection power to present large images in venues where ambient light would be a problem for lesser projectors. The horizontal keystone correction slider bar makes it easy to create a perfectly rectangular image no matter where you place the projector. Because of the 1.6x optical zoom, larger images can be displayed from shorter distances, saving valuable space in the classroom or boardroom.
