The 56H80 Theaterwide is a 56-inch diagonally measured HDTV monitor with a 16:9 aspect ratio. It has most of the bells and whistles that we have come to expect from a top-of-the-line rear projector. The feature list is huge and includes favorite channels, channel labeling, picture-outside picture, favorite channel search with picture, input locks, sleep timer, clock, SRS Tru-surround, and sub-bass.
