    Maybe the resolution isn't supported. Can you change the output resolution and see if others work? Try 1024 x 768, 800 x 600 and 640 x 480 if that is possible. Don't know whether you can or how to do that as I've never had a mac, I'm afraid.

    did you click the "detect displays" button in the display preferences?

    The included mini displayport to dvi adapter is digital only. Using a dvi to vga adapter will physically fit, but the pins and signal aren't there to get the crt to display.

    The only way to make a vga monitor display a picture from the mini displayport is via Apple's mini displayport to vga adapter.
