A wall controller is a device supporting 1 HDMI or DVI input and several HDMI outputs. The main function of a wall controller is to divide the full HDMI or DVI HD image into several blocks and assign them to several video units (such as a screen, projection unit, LCD TV, etc.). Thanks to the device, it is possible to create a large, dynamic, high-quality image, the so-called video wall.
Key features of video wall controllers: - large image on several displays from one source - high display resolution without loss of quality - many display modes, e.g. 1:2, 1:4, 2:2, 2:4, 2:4, 3:3, artistic mode - simple, intuitive operation
