The Aten CubiQ CS1764A USB 2.0 DVI KVMP Switch combines 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 through DVI. It comes with ATEN's Video DynaSync technology, which is designed to optimize display resolution, and power on detection, which means if one computer is powered off, the unit will automatically switch to the next powered-on computer. As a KVM switch, it allows users to access two 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.
