This Displayport switch allows you to to plug two Displayport cables into one screen, and easily switch between them. this is useful if you have two computers but only one screen (or set of screens) to connect to either computer at a time. Alternatively, you can use the displayport alternator switch in reverse, meaning you can have one computer plugged into two screens (or a screen and a projector, perhaps, and you can switch instantly which display to use without changing cables around. Displayport cables not included.
