The Gefen EXT-HDTV-444N  is a 4x4 HDTV Matrix which routes high definition video in multiple resolutions up to 1080p from any of the four HDTV sources to the displays. Four outputs gives you the choice of sending high definition video signals up to four displays. Any four to any four matrix switching allows for maximum versatility for integrated systems. This HDTV matrix switch eliminates the need to disconnect and reconnect sources to a display equipped with one input. It works with HD-DVD players, TiVo systems, HT PCs, and satellite set top boxes that connect to a DVI display. Every source is accessible at all times by any display by selecting it with an IR remote.
