    I didn't know where else to post this because technically it's a PC issue. I felt people familiar with apple products can give insight since it's an Apple display.

    I just bought a used graphics card (Radeon HD 6870) because it has mini displayports for the sole purpose of connecting to my Apple Cinema Display (LED version).

    I've tried inserting the mdp that comes out of the ACD into the graphics card and nothing happens. At all.

    The graphics card itself works just fine when I use the DVI to my dell.

    I'm not sure if it's the ACD not being compatible or the ports being inactive/dead. I'm not sure how to test for the latter since I don't have any other mdp devices.

    I'm really stumped. I want to clear up my desk and just use my ACD alone.

    Did you install/reinstall the bootcamp drivers, perhaps its missing those.

    Sorry forgot to mention I'm running it on an actual PC not bootcamp
