Since HDMI (and DVI) digital signals have cable distance limitations, the SW-HDMI-4 provides the ability to boost the output signal to drive long HDMI cables to about 50 feet. Furthermore, the unit has built in automatic equalizers on the inputs so that it can handle long input video cables (to 65 feet).
