The ATEN VS84 VGA Video Splitter duplicates the video signal from an input source (i.e. a computer) and routes it to up to 4 display devices (monitors, projectors, etc.). However, they go beyond being merely duplicators, in that they also enhance the video signals over distances up to 65 meters away. Furthermore, they can be cascaded three levels to additional ATEN video splitters to support many numerous display devices. And they mount inconspicuously on the wall or out of sight due to their small size.
