Some graphics cards don`t like it when they are notconnected to a
monitor or at least a cable. I only found out about that, when I
bought a real magic card a couple of years ago and it came with some
kind of VGA connector plug which could be plugged into the VGA card,
because the real magic card was connected to it via feature connector
and the monitor was connected to the real magic card. I never had a
VGA card that needed it, though.
