A video wall is a large display composed of multiple smaller screens or projectors tiled together to create a single cohesive image. Video walls are often used in commercial and public spaces, such as control rooms, lobbies, and stadiums, to display information, advertising, or entertainment.
There are many factors to consider when building a video wall, including the size and resolution of the display, the type of content that will be displayed, and the viewing environment. It is also important to consider the cost of the video wall and the ongoing maintenance costs.
