    Hello there

    I hope you can help.

    I want to use an extra external display together with my Imac27 - I have a MBA that I would like to use, just to have a little extra screen for some things.

    How do I set it up, I'm not sure which ports and cables I need to use.

    Do you already have the display?

    If so, what connection ports are on the back of it?

    I want to use my Mac book Air computer as a display... I know how to get the display out of that one - but not how to get a display INTO it.

    The ports I'm looking at tell me.. I've attached two pictures :eek:
