    Can't get DisplayPort to DVI working on iMac (same cable works fine on MBP)
    Hello all,

    Wondering if anybody could give me some advice.

    I recently bought a new monitor and cable.

    I am trying to output my 27" iMac to the new monitor via a direct DisplayPort to DVI cable (no adapter or anything), and it won't seem to detect the display.

    I tried it on the girlfriends MacBook Pro to her monitor and the cable worked perfectly.

    The monitor works fine, had it working on D-Sub and HDMI perfectly.

    The iMacs DisplayPort works fine also, had this successfully outputting to a TV via D-Sub.

    Any ideas?

    Many thanks.

    Stuart.

    Edit: Resetting SMD and PRAM didn't work either.

    Specs:

    Which 27" iMac do you have Stuart? The latest 27" iMac for example, has a Thunderbolt output video port which is not going to work with a direct cable connection.

    Just tried it with a dvi to hdmi adapter, works perfectly.

    Weird...

    Edit: Just tried it with an official Apple adapter to DVI, that works. Must be the cable then.
