With KVM; it's as if you power on your computer. So the monitor is already connected to your computer, but the computer is powered of. Then you power on your computer and the monitor detects the video signal. This is what happens when you switch the KVM.
Plugging and unplugging the screen is not the same as KVM, and yes; you could fry both ends. You should use a docking station instead. Cheers!
