Belkin Secure SKM products differ from SKVMs in that each connected computer can have its own dedicated display rather than sharing one or two between them. Belkin KMs support up to four displays per connected computer.
When connecting more than 1 display to a computer, you will need to install the Multi-Display Driver found on the Belkin support site for your KM. Without installing this, your computer will display on all monitors connected to it, but your mouse cursor will not move past the primary display of that computer.
NOTE: This driver is only required for Windows® computers.
