The Gefen EXT-DVI-841 is a plug and play solution, the 8x1 DVI Switcher connects eight digital video source devices, such as DVI-based computer systems and links them to one DVI display. You select what source will be viewed on the display using the IR remote control or through RS-232 control. The discrete IR codes can also be programmed into any universal remote device, offering an alternative to multiple remote control confusion.

Simply connect your DVI display to the Switcher's display output. Then, using the eight high quality DVI cables that come with the 8x1 DVI Switcher, plug each one into the eight DVI source devices, then connect them to the Switcher's inputs. Once the source devices and the display are powered on and connected, you switch between source devices using the RMT-8IR remote control or your own universal remote.
