Video walls are used for business information, as well as entertainment. They are also useful in very large places where information needs to reach massive crowds, such as Malls, Stadiums, Retail Stores, Commercial Establishments like Schools, Colleges and airports. A video wall is a large display consisting of more than one video screen fixed together to form a single logical screen. A video wall can be formed using LCD or LED computer screens, traditional television sets and video projectors. They can also be formed in the traditional square or rectangular shape of a television, or a less traditional shape. When a video wall is created by combining several videos, the screens used often have ultra-thin edges called bezels to make a disruption in the picture between screens less noticeable. The screens are commonly connected together using a daisy chain method so that a command such as turning the video on or off works on all of the screens at once. Video wall displays are usually made from a tiled arrangement of monitors, panels, or projection screens. Tiling multiple displays together can create an extremely large, multi-HD display surface.

Video walls come in a large range of display technologies, including LCD, LED, projection cubes, blended projection, and more. Each display type offers unique advantages and limitations in terms of resolution, brightness, reliability, cost, and other factors. Depending on the display type and mounting system selected, video walls can be built in flat, curved, or even three-dimensional shapes. They can be small enough to be portable or large enough to fill a multi-story atrium.
