The CS1764A USB 2.0 DVI KVMP Switch charts a revolutionary new direction in KVM (Keyboard, Video, Mouse) switch functionality by combining a 4 port KVM switch with a 2 port USB 2.0 hub at the same time as it provides an interface for a digital monitor (DVI). In addition, the CS1764A comes with ATEN’s new Video DynaSync technology, which optimizes display resolution, and power on detection, which means if one computer is powered off, the CS1764A will automatically switch to the next powered-on computer. As a KVM switch, it allows users to access two or four computers from a single USB keyboard, USB mouse, and monitor console. As a USB 2.0 hub, it permits each computer to access any peripherals connected to the hub on a ‘one computer at a time’ basis.
