I have a desk with a Windows 10 PC and an Ubuntu Linux PC, both configured for dual display use. In the past, if I wanted to switch computers, I had to switch the source for both monitors. I just press a button on the switch and instantly move my keyboard, mouse, and two 32-inch monitors to the other computer. Reduces wear and tear on the monitor and also uses only one HDMI port per monitor instead of two.
