Auto switchers give you the ability to switch between multiple and similar input sources such as HDMI, DisplayPort, and VGA, and then send the desired signal to a single display device such as a flat panel or projector. From two to eight sources can be sent over a single HDMI cable, or there are some switchers that have a built in twisted pair or HDBaseT integrated transmitter that allow the signal to be sent over an Ethernet cable. All our switchers are auto sense switching, they detect the input and then automatically switch based on the last plugged in device. This means no more running multiple cables to your TV or projector, just run one cable! The best part of an auto switcher is that you no longer have to switch sources on the remote or TV every time a different input is plugged in. If you need help selecting an auto switcher just let us know.
