A video wall is a particular configuration of many screens, such as those from several computers, video projectors, or televisions, that are tiled together contiguously or overlapped to produce a single huge screen. Direct View LED arrays, blended projection screens, Laser Phosphor Displays, LCD panels, and rear projection cubes are only a few of the common display technologies used today. Previous uses of jumbotron technology are also referenced.
Displays intended for usage in video walls typically have low bezels to reduce the visible space between individual screens and are constructed with durability and longevity in mind. Common features of these displays include connections for daisy chaining power, video, and command signals between displays, as well as technology that allows for stacking displays of the same type.
Due to the economics of creating single displays which are uncommon in shape, size, or resolution, the video wall is sometimes referred to as a single giant screen for a variety of reasons.
While multi-monitor video cards can power basic video walls, more sophisticated setups may need video processors specialized to handle and power massive video walls.
Video walls can also be implemented with software-based technology that only requires regular computers, monitors, and networking hardware. It's not uncommon to see video walls in places like stadiums and command centers where viewers are positioned to take in the show from great distances.
Since video walls have become more inexpensive and scalable, many smaller enterprises have hopped on the bandwagon, recognizing that this technology can assist them be more productive and boost their brand visibility, much like the big brands and Fortune 500 corporations have.
