    Looking to dual monitor old imac with new imac
    My wife has a roughly 5 year old imac with a thunderbolt connection and the new one has a type c style thunder bolt connection.

    What cable would I need to make the new use the old as a extended screen?

    Thanks for your reply

    Yes I did see that when I searched for it. I just wanted to know if there was different cable or something.
    As of right now I was thinking about getting thunder bolt 2.0 adapter to hdmi then thunder bolt 3.0 to hdmi and then hdmi in the middle.

    Basically these

    You should be okay as long as you follow the directions as given in the Apple article mentioned in Bob's reply to you. And yes, the Amazon cables should work, but if there is a problem you can always return them for a refund from Amazon.

    And.. Welcome to our forums.
