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 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.
