The Vista AV 2 x 1 DVI Video Switch from Rose Electronics is used to switch your DVI video from two DVI video sources (usually a multi-platform computer) to one centralized monitor. The video from each video source can be switched to the local monitor via the push of a button on the front panel, or by using remote serial commands from a connected computer or controller. The multi-platform design gives you the option of connecting Windows, Mac, Linux, and Sun Systems to the Vista AV and seamlessly switching between systems.
