    Hi there,

    I need some expertise from you guys!

    I have a Mac Book Pro 15" medio 2014. I want to use my iMac 27" medio 2010 as an external display when I create music in Logic.

    I've connected via
    Thunderbolt Mbook to mini display port iMac.
    HDMI Mbook to mini display port iMac.

    When I go to System preferences/ Monitor (display) there is no options available. When i connect a regular monitor the option is there.

    What do I do wrong? Or is it even possible.

    Thanks,

    Dr. HaNzN

    What Dave failed to point out is on Apple's own website has additional, but key, details - from your OP, you do not have the correct cable. You need a Mini DisplayPort to Mini DisplayPort cable for your intended connection.

    See this: http://support.apple.com/en-us/HT3924

    FWIW, I was wondering this just last night for my own reasons and bookmarked it! I have found that DP cables work great when TB cables don't.
