The Gefen EXT-DVI-422N is a 2x2 DVI Switcher which enables you to switch easily between two cross-platform digital video computers using dual DVI displays controlled by a USB keyboard/mouse combination. This DVI KVM switch "switches" high resolution digital video, keyboard/mouse controls and audio between each computer instantly, providing you with an effortless way to access two computers from the same workstation without complex networking.  The term dual displays is usually used to describe two monitors that are running an extended desktop setup, so that the same image extends over two displays, providing you with a wider digital desktop.  The 2x2 DVI KVM switch will not mirror the same desktop but will provide support for dual displays.

How the Gefen EXT-DVI-422N works:

Connect both computers' DVI, USB and audio ports to the Switcher's inputs using the cables provided. Then you connect both of your DVI displays, USB keyboard/mouse and optional audio device to the two outputs on the Switcher. Switching between computers is done from a key switch or remotely using a contact closure remote control.

Note: Apple flat panel displays equipped with ADC (Apple display connector) can be connected when used with the Gefen DVI to ADC Conversion Box.
