VW-4 Is a 4-output video wall driver designed to quickly and easily configure and manage video walls. Use one VW-4 device to create any wall configuration with up to 4 displays, for example, a 2x2, 4x1, 1x4, 2x1, 3x1 video wall. Connect additional devices to create walls of any size and configuration of up to 64 displays. Configure a single or multiple device setup using the VW-4 app via Ethernet or RS−232, or quickly configure a basic setup using the local dip switches.
