Trouble connecting to projector, Precision M6400 and M4400
I am unable to connect my laptop to a projector using a VGA cable. When I press the Fn + F8 keys the menu pops up to change the display output but nothing happens. I've tried right-clicking the desktop and changing the settings but it doesn't recognize a second monitor. I've also tried reducing the screen resolution. I've tried these steps with presentation mode both on and off. Any assistance is greatly appreciated.
