Now you can easily combine four cross-platform computers and four digital displays without networking. Our 4x4 DVI Matrix provides a simple, reliable and highly effective method of creating multiple computer workstations, with each capable of accessing any one of the computers or sources at any time by remote control. You also have the option of setting up the four stations locally or extending them with a Gefen extender. When used with computers, USB control signals follow the DVI input for optimal control.

How it Works:
The 4x4 Matrix Switcher has four DVI inputs and four DVI outputs. You simply connect your four computers's DVI ports to the Switcher's inputs, then connect your four DVI displays to the Switcher's outputs. USB keyboard and mouse signals, once connected, follow the DVI switched input for each computer.
