To distribute and switch the latest in 4K (3840x2160 @30Hz) HDMI video signals, the HDR-4x4-Plus allows users to independently route four inputs to four displays. Four outputs give users flexibility while routing HD audio and video signals with four displays. The HDR-4x4-Pro eliminates the need to disconnect and reconnect HDMI sources to a single display. The device is compatible with computer sources, live HD television feeds, Blu-ray players, gaming consoles, video cameras and more. Controlling the matrix switch is simple with the front-panel buttons, the included infrared remote control and the RS-232 port.
