The Gefen EXT-DVIKVM-444N is a 4x4 DVI KVM Matrix which provides an effective method of creating multiple computer workstations, with each workstation capable of accessing any one of the computers or sources at any time by remote control.  This DVI KVM matrix switch allows you to switch four cross-platform computers to four digital displays. You also have the option of setting up the four stations locally or extending them with a Gefen extender.  When used with computers, USB and Audio Matrix control signals follow the DVI input for optimal control.

How the Gefen DVI KVM Matrix switch works:

The 4x4 DVI KVM Matrix has four DVI inputs and four DVI outputs. Connect your four computer's DVI ports to the Switcher's inputs, then connect your four DVI displays to the Switcher's outputs. USB keyboard and mouse signals and analog audio, once connected, follow the DVI switched input for each computer.
