Gefen Inc EXT-HDMI1.3-444
4x4 HDMI 1.3 Matrix


Gefen's EXT-HDMI1.3-444 4x4 HDMI 1.3 Matrix routes high definition at resolutions up to 1080p with multichannel digital audio from any four HDMI sources to any four displays.  The 4x4 Matrix eliminates the need to disconnect and reconnect HDMI sources.  It works with any HDMI source that connects to an HDMI display, supporting advanced digital audio formats such as Dolby TrueHD and DTS HD Master Audio.  Each source is accessible at all times by any display by selecting it with an IR remote, or using the RS232 port to switch the unit.

Fully HDCP Compliant

HDCP (high-bandwidth digital content protection) is a standard digital code embedded in the HDMI video signal to prevent it from being pirated.  HDCP-encoded source video that is fed into equipment not having the proper decoding mechanism will be transformed to "snow" or very low (480P) resolution images.  For proper, full-resolution HDTV video rendition, the source and display (and anything in between) must be equipped with HDMI circuitry that decodes HDCP properly, such as the 4x4 Matrix for HDMI 1.3.
