What is Video Wall?

A video wall is a large display surface assembled from multiple panels — typically 2×2, 3×3, or larger arrays of LCD or LED tiles — driven from a digital signage CMS so the array shows either one logical canvas or independently-addressable per-tile content. The use cases split into three: marketing impact (a single hero canvas in a flagship retail location or airport hall); operational dashboards (control rooms, trading floors, hospital triage); and brand presence in banking branch flagship or government one-stop-shop lobbies. The hardware decisions matter — bezel width determines whether the seams between tiles disrupt content, brightness rating determines whether the wall works in a sunlit airport hall, and the controller (PC, dedicated processor, or networked edge player) determines the scalability ceiling. The software decisions matter just as much — a good CMS treats the wall as a single canvas the content team designs against, then automatically splits the canvas across tiles at render time.
