Access up to Four Sources From One or Two DisplaysThis product has been replaced by the Gefen EXT-HDMI1.3-442
Gefen's 4x2 HDMI Switcher routes high definition video in multiple resolutions of up to 1080p plus multichannel digital audio from any of four sources. The inputs accommodate the simultaneous connection of up to four high definition video sources, such as satellite systems and HD DVD players. Two outputs send the high definition audio/video signals to up to two high definition displays. A digital audio output port is available if you need to direct the audio to an audio receiver. Switching is done via the IR remote that is provided with the unit.
How It WorksYou simply connect all your sources to the Switcher's inputs. Then connect up to two displays on the output ports. Once the sources, the Switcher and the display(s) are powered and connected, you simply select which source you want to view using the included IR remote.
