Easily Switch Between Four HDTV Devices Using One HDTV Display

The Gefen 4x1 HD Switcher (EXT-HD-441) enables effortless HDTV source switching using a single high definition display. A simple and reliable solution, the 4x1 HD Switcher (EXT-HD-441) links any four HDTV sources (DVD players and satellite set tops) to one HDTV display. It completely eliminates the need to disconnect then reconnect multiple HDTV sources, saving time by providing a fundamental tool that brings it all together behind the scenes. When all five devices (the display plus the four sources) are connected to the Gefen 4x1 HD Switcher (EXT-HD-441)r 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 product will ONLY support digital video signals.

Fully HDCP Compliant

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

How it Works

Simply connect your HDTV display to the Switcher's display output. Then connect both HDTV sources to the Switcher's inputs using the HDMI cables that come with the Switcher. Once the sources, the Switcher and the display are all powered on and connected, you simply select which source you want to view.
