The Gefen EXT-DVIKVM-441 is a 4x1 DVI KVM Switcher which provides flexibility in integrating cross platform computer equipment easily and without networking. It enables you to switch easily and reliably between any combination of four DVI (digital visual interface) computers using one DVI display.  This DVI KVM switch also supports USB 2.0 for USB keyboard/mouse and other high speed peripherals. Audio is switched for each computer as well, allowing for the creation of multimedia desktop environments, and you can even choose between a Macintosh or PC keyboard/video/mouse combination. Switching can be controlled through either the IR Remote, Front Panel Push Buttons, or the Contact Closure port.

How Gefen EXT-DVIKVM-441 works:

Plug your display, keyboard/mouse and audio peripherals directly into the 4x1 DVI KVM switch's outputs and connect the supplied cables to the four computers you want to control. You then select the computer you want to work on using remote that comes with the unit.

Note: Switching between computers is done from the 4x1 DVI KVM Switcher remotely using the infrared RMT-4IR remote control, front panel push buttons, or the wired RMT-4 remote.
