The What: The SW-HD-4 is a 4 input HDMI Switcher with InstaPort Technology from Silicon Image enabling fast switching of four HDMI sources to a single HDMI output. The switcher supports 4K (UHD), 3D, 36-bit Deep Color video. Control switching via front panel button, using IR remote control, RS-232, Telnet, and also web GUI built in the unit.
