I have a laptop that is hooked up to a monitor via a VGA cable. I'm trying to get the display set to the external monitor only (I don't want any display on the laptop screen). However, whenever I set the laptop display to "off" in the "Displays" setting, their isn't a display on either (the laptop screen and the monitor have no signal). So, how do I get it to where the display only shows up on the external monitor?
