VIDEO WALL
A video wall is large screen made up of several monitors, placed close to one another, which, when viewed from some distance look like a large video screen or wall. A digital processor breaks down the original video or graphic image into several pieces, by converting the analog video signal to digital, rescanning and resampling it, and generating individual analog video outputs for each monitor. The unit is relatively expensive, and is used, as are wide screen projectors, mainly for public viewing.
