The IOGEAR DVI KVMP Switch GCS1104 charts a direction in KVM switch functionality by providing an interface for today's digital monitors while integrating a 4-port USB KVM switch with USB 2.0 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 USB 2.0 peripherals such as external hard drives, printers and scanners. The GCS1104's independent 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. The GCS1104 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 and analog video input.
