Mac Cinema Display as a second display for my iMac 2015 21.5 inch

I am trying to use this Mac Cinema Display as a second display for my iMac 2015 21.5 inch and it has two thunderbolt 2 plugs and four usb's. The second display has 3 cables that I am not sure that I need to plug into my iMac. What cables do I need to plug in? I need to know this so I can get the correct adapters. Thanks.

Connect 2022 Mac mini to iMac to use it as a display I have a brand new Mac mini m1. I have 2 iMac 27”, 2013 and 2015. My understanding is I can’t do this with the 2015 iMac. Mini came with a thunderbolt cable. But it looks like the iMac thunderbolts are incompatible. Can you suggest the easiest and cheapest way to connect this new thunderbolt cable on iMac, assuming there is an adapter. If not, please suggest other cables. A link to the cable would be appreciated so I get the right one. TIA! [Re-Titled by Moderator]

Hi there,

There are several types of Cinema Display. Is the front bezel black or silver?

Cheers,

Jack

That may work. However, be prepared to return it. Sometimes Apple used a slightly different DVI.

so if/ when I get that and connect it to my computer, do I need to plug in any of the other cords or is the dvi the only cord I need?
