The Gefen GTB-HD4K2K-442-BLK is an HDMI 4x2 4K UltraHD matrix, capable of routing four UltraHD fonts to two UltraHD displays, with FST, 3DTV and 4K x 2K UltraHD support. It is a compact and lightweight solution to rack-mounted dies. Allows up to four UltraHD high definition 4K or 1080p FullHD sources to be routed to up to two UltraHD displays. This product supports resolutions up to 4K (3840x2160@60Hz 4:2:0 or 30Hz 4:4:4) and 4K Cinema (DCI) (4096x2160@24 or 30Hz 4:4:4). HDCP, Deep Color, 3DTV signal support and lossless audio formats such as LPCM 7.1, Dolby TrueHD and DTS-HD Master Audio. Each HD source can be routed to any of the connected screens using the front panel button controls, the included IR remote control, the RS-232 serial control interface, or via IP, using Telnet, UDP, and Built-in web server interface. The top panel LEDs show the current routing status, FST mode, audio settings and EDID settings.

Fast Switching Technology (FST) is a Gefen software implementation for HDMI products. FST eliminates the lengthy process of HDMI authentication and allows you to connect/disconnect or turn on or off HDTV screens without these activities affecting other screens in the same distribution system.
