The Video Separator is a signal booster and splitter that is used to take video input from a single source and direct it to two video outputs for monitors using analog signals. The signal boost obtained by using the VS92A allows you to not only split the signal but to extend the distance so that you can send the signal to about 210 feet. (Your average VGA card combined with a standard VGA cable can send a clear VGA signal approximately 25 feet.) This makes public broadcasts from a single computer very feasible. If you want to display the same information on many monitors at once such as in a classroom environment or at a demonstration this product performs incredibly well.
