The extendit Mini DVI Switcher enables effortless DVI video source switching using a single DVI display. A simple, reliable and economical solution, the Mini DVI Switcher links any two DVI sources to one DVI display. It completely eliminates the need to disconnect then reconnect multiple DVI sources, saving time by providing a fundamental tool that brings it all together behind the scenes. When all three devices (the display plus the two sources) are connected to the Mini DVI Switcher and powered on, you simply select which source you want to view on the display using the Switcher, the IR remote that comes with it, or any universal remote you program to work with the Switcher. Simply connect your DVI display to the Switcher's display output. Then connect both DVI sources to the Switcher's inputs using the DVI cables that come with the Switcher. Once the sources, the Switcher and the display are all powered on and connected, you simply select which source you want to view.
