Marketing Description:  The IOGEAR DVI KVMP Switch GCS1764 charts a revolutionary new direction in KVM switch functionality by providing an interface for today's digital monitors while integrating a 4-port USB KVM switch with USB peripheral sharing capabilities. As a KVM switch, the unit allows the user to access four computers from a single USB keyboard, USB mouse, and monitor, and also share among the computers peripherals such as external hard drives, printers and scanners. The GCS1764's independent (asynchronous) switching feature allows the KVM focus to be on one computer while the USB peripheral focus is on another. The user can switch from one computer to another without interrupting print jobs, downloads or other functions being handled by connected peripherals. This eliminates the need to purchase a separate USB hub as well as the need to purchase separate stand-alone peripheral sharers - such as printer servers, modem splitters, etc. The GCS1764 further improves on previous designs with DVI (Digital Video Interface) connectors, and the transfer of keyboard and mouse data to the computers via a fast, reliable USB connection. DVI supports both digital input (flat panel displays, data projectors, plasma displays, digital TVs and set-top boxes) and analog video input (traditional monitors and TVs).
