Thunderbolt 2 to Display Port

I assume you want to use this with a DisplayPort compatible monitor:

• Yes you can. As you quote:

However, [Thunderbolt 2] does support Mini DisplayPort for video output

This is definitely correct and I can confirm that this works on a similar machine. The cable you show should work as intended.

What doesn't work is using a Mini DisplayPort as Thunderbolt 2, e.g. for transferring data to a hard drive. But you want to use Thunderbolt 2 as a video output, which is one of the intended use-cases of TB2, similar to the newer TB3, USB-3 and USB 4 (which in theory equals TB 3) connectors.
