A video wall consists of a plurality of individual video display units, usually standard television monitors, either of the direct-view or projection type, that are placed with their viewing screens adjacent to each other in a two-dimensional array. Large video walls are often designed for information display purposes, including public performances and public events. A video wall is commonly comprised of several smaller rear projection screen panels. Each panel of the video wall then receives a portion of the overall picture resulting in an enlarged total image. Typically, the screens are held in place by integral frame members which must support the weight of each screen to prevent warpage of the lower screens.
