Gefen Inc EXT-VGA-4X1

Switches VGA, USB 1.1 & Audio between any four computers
Or 4x1 VGA Switcher allows you to connect and access up to four cross-platform computers from the same workstation easily and reliably. No need for networking--everything is connected and routed through the small metallic Switcher. It switches analog video (VGA), USB keyboard/mouse controls and audio capability for each computer.

How it works
Simply plug your peripherals directly into the back of the Switcher, connect the cables to the computers you want to control, push to select the computer you want to work on, and you're switching. The VGA Switcher allows you to choose between a Macintosh or PC keyboard/video/mouse combination. Switching between computers is done from a key switch or remotely using contact closure remote control.
