The ATEN VS84 Video Splitter duplicates the video signal from an input source (i.e. a computer) and route 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 98.5 feet (30 m). 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.
