iMac 27″ 2009 to iMac 27″ 2014 (MiniDisplayPort/Thunderbolt 1).

if it’s an old iMac with Target Display Mode* support), use this cable (or something similar) : If your external screen had a MiniDisplayPort-input (e.g. if it’s a slightly older or more professional display), use this cable (or something similar) : If your external screen has a DisplayPort-input (e.g.

Thunderbolt 3 (TB3) and regular USB-C (USB 3.1 gen 2) connectors look exactly the same, but Thunderbolt 3 (TB3) runs at 40Gbps instead of 10Gbps for regular USB-C.
