I have a Dell 1100MP Projector. I am hooking it up to my GX280. I connect the projector to the computer and I can see the Windows logon screen, and then I connect my monitor to the VGA out the projector says "Please change VGA cable to "Monitor In"." I thought the projector acted as a VGA pass-through, then why does it keep displaying this message that makes no sense?

 

Any Help would be appreciated.
