Im running a Dell Latitude D600 and am trying to project a presentation using an extrernal DLP projector. The computer displays all the information on the screen correctly however when I hit Ctrl+F8 to switch from the LCD screen on the laptop to the external projector the picture displayed on the wall, screen, etc is all garbled and jumpy. Every time that I attempt to switch to the projector an error message comes up stating "The resolution that you are using is less than your best resolution (1400x1050). I hit the Ctrl+F8 again and return back to the laptop and everything works fine. So far I have tried changing the different screen resolutions, changing the settings in the video card (ati radion 9000) for multiple displays, and reinstalled the video card drivers and still not working. I dont really know where else to go on this problem.
