Ok, this one is killing me. I'm trying to get my new Alienware M17X laptop to recognize an external projector to use for presentation. I know the projector is working fine, because I put another laptop on it with no problems. I've tried both HDMI as well as VGA cable, and I get nada... the laptop does not seem to see the projector. Any thoughts or advice would be much appreciated. OS I'm using is Vista Ultimate - 64.
