Me too, but no KVM.  If the monitor lost video signals (like the PC
blanking, going to sleep, or shutting down), the monitor would try the
other inputs, then quit and die.

If the PC came back, the monitor was not checking inputs for new
signals, and you had to fight with the monitor to get it on and select
the right input:  It didn't want to turn on without a signal, on-screen 
displays don't work well when the monitor has a blank screen, monitors
are ludicrously slow at changing input signals these days, yet will let
you zip past the one input with an actual signal.

I long for the old days where a three input monitor had input 1, 2, 3
buttons on the front, and instantly changed over as you pressed each
button.

To avoid that pain, again, my monitor has input scanning switched off,
now and forever more.
