About Gefen 4x4 Matrix

Route four Hi-Def sources to four Ultra HD displays with FST, 3DTV and 4K x 2K Ultra High-Definition support
The GefenToolBox 4x4 Matrix for HDMI 4K x 2K is a compact and lightweight alternative to rack-mounted matrixes. It allows up to four Ultra High Definition 4K x 2K or 1080p Full HD sources to be routed to up to four Ultra HD displays. This product supports resolutions up to 4K x 2K (3840 x 2160 at 30Hz). Deep Color, 3DTV pass-through and lossless audio formats such as LPCM 7.1, Dolby TrueHD and DTS-HD Master Audio are also supported.

Each Ultra Hi-Def source can be routed to any of the connected displays using the front panel push-button controls, the included IR remote, RS-232 serial control interface or through IP, using Telnet, UDP and the built-in web server interface. LED indicators on the top panel display the current routing status, FST mode, audio configuration and EDID settings.

FST
Fast Switching Technology (FST) is a Gefen software implementation for HDMI products. FST eliminates the lengthy HDMI authentication process and allows connecting/disconnecting or turning ON / OFF of HDTV displays without having these activities affect other displays in the same distribution system.

How It Works
Connect up to four Ultra Hi-Def sources to the HDMI inputs on the matrix, using HDMI cables. Connect up to four Ultra HD displays to the HDMI outputs. Connect an Ethernet cable from the network to the RJ-45 connector to use the built-in web server or Telnet/UDP capability to control routing, EDID management and other functions. Connect an RS-232 cable between an automation control device such as Gefen EXT-PACS or GTB-MINI-PACS and the matrix.

Connect the included locking power supply to the matrix and to an available electrical outlet. Apply power to the sources and displays. The HD sources can now be routed to the displays using the front panel push-buttons, IR remote control, RS-232, Telnet, UDP or web server interface.
