The Gefen EXT-VGA-422 is a 2x2 VGA Switcher which enables you to connect and access two computers using one workstation equipped with dual VGA monitors and one USB keyboard/mouse. Analog video, keyboard/mouse control and audio are "switched" for each computer, providing you with an easy and effective way to alternate access to greater amounts of data at the touch of a button.  Dual monitors, in this case, refers to the use of two monitors that are running an extended desktop setup so that the entire digital image is extended over two monitors providing a greater digital desktop on which to work. The VGA switcher will not mirror the same desktop but will provide support for dual displays.

Note:  The 2x2 switcher will NOT switch between four computers and two displays or four computers and one display.

How the Gefen 2x2 VGA switch works:

Connect both computer's VGA video, USB and audio ports to the 2x2 VGA Switcher's inputs using the supplied cables. Then you connect both VGA displays, the USB keyboard/mouse and an optional audio device to the Switcher's outputs. Once powered and connected, you switch between computers by key switch or remotely using contact closure remote control.
