    So my buddy brought over his first-generation-aluminum 20" cinema display. I have a DisplayPort to VGA connector, and a vga-dvi converter, and I plugged the cinema display into that. Nothing is showing up on the cinema display - it's just black.

    And yes, I turned it on.

    Any solutions?

    You need a Mini DisplayPort-DVI adapter. You can't go to VGA and back.

    20" Cinema Display to Macbook Pro

    I'm having this same issue. I bought a used 20" display at a yard sale for super cheap. They said it worked fine, and I gave the benefit of the doubt because it was a steal.

    Now I've got it plugged into my Macbook Pro with a mini diplay port to vga adapter, and it is recognized by my laptop but the screen stays black. Does that mean the monitor is broken? Or is there something else I need to do?
