The 2x1 HDMI Switcher enables effortless HDMI source switching using a single high definition display. A simple and reliable solution, the 2x1 HDMI Switcher links any two HDMI sources (DVD players and satellite set tops) to one HDMI display. When all three devices (the display plus the two sources) are connected to the 2x1 HDMI Switcher and powered on, you simply select which source you want to view on the display using the Switcher, the IR remote that comes with it, or any universal remote you program to work with the Switcher. This HDMI product supports both Audio and Video signals.
