Userful's Video Wall solution enables customers to group together multiple stations to form a single large display, thus enabling a single host PC to support one or more larger displays. This is possible because of the high performance and throughput of Userful's zero-client solution and the high performance video splitter developed by Userful. Video Wall is supported in a variety of configurations (e.g. 5×5, 4×2, 1×10) and layouts (equidistant grid, or free-layout and artistic).
