Dual Monitor/Projector not working with laptop

[kingjaydub]

I have a Dell E6410 and I can't get a second display to work on it. When I got into the display options and try to detect a second monitor or projector hooked to it, it doesn't detect anything.
The drivers are all updated and I've tried using the function + F8 key to get it to work.
I noticed today that if I'm in the BIOS and I close the lid to the laptop it will display on the projector, but once Windows boots it won't display on the projector no matter what I do.

The Dell laptop does not witch to external  monitor unless there is a monitor in place and you have the right drivers installed.
