Say, you have your system running, and you want swap the monitor. Or
re-route the cable better. Or just close the laptop lid (I hear that
might cause the LVDS to disconnect). Or have a mechanical video switch
which causes the display to appear disconnected when not selected.
But none of that is a reason in itself to have a fake output.
