The B004-DUA4-K-R is a 4-Port DVI/USB KVM Switch with audio and USB 2.0 peripheral sharing. It allows you to access control boot and reboot four computers from a single USB keyboard USB mouse and monitor. Switching between connected computers is quick and simple using keyboard hotkeys or pushbuttons. An independent audio/mic and USB peripheral switching function allows for an uninterrupted experience. A computer can be printing on a printer connected to one of the USB 2.0 peripheral ports while you listen to audio from and access another computer; all at the same time.

A DVI to VGA adapter such as Tripp Lite's P126-000 is required for conversion to an analog monitor. Whichever you use full time DDC support provides the necessary EDID information required for optimal video performance on Windows 7 and other operating systems.
