Gefen's 4x1 HDMI Switcher (EXT-HDMI-441) routes high definition video in multiple resolutions up to 1080p plus multi-channel digital audio from any of four sources. Four inputs accommodate the simultaneous connection of up to four high definition video sources, such as satellite systems and HD DVD players. The output sends the high definition audio/video signals to a high definition display. Switching is done via the IR remote that is provided with the unit.

The Gefen 4x1 HDMI Switcher (EXT-HDMI-441) product supports BOTH Audio and Video signals.

Fully HDCP Compliant

HDCP (high bandwidth digital content protection) is a standard encoded into the video signal to prevent it from being pirated. If a source device is HDCP coded and is connected to a display or projector without the proper decoding mechanism, the picture is relegated to "snow" or in some cases, very low (480P) resolutions of the images. In order to see high resolution digital video with HDCP compliance, both the source, the display and anything in between must be equipped with HDMI connections that can enable HDCP decoding, such as Gefen's 4x1 HDMI Switcher (EXT-HDMI-441).

How it Works

You simply connect all your sources to the Gefen's 4x1 HDMI Switcher (EXT-HDMI-441) inputs. Then connect the display on the output port. Once the sources, the Switcher and the display(s) are powered and connected, you simply select which source you want to view using the IR remote.
