Displayport not working

[Derpintosh]

Hey
My System won't boot over a specific DP of my GPU (RX 580), it just stops half way at the bootlogo and shifts to a blackscreen.
The other ones work fine, but only the one that wont work with OSX is fully functional, the rest will just output blackscreens under load (Hardware Issue), therefore i must get the other one up and running. Windows has no problem using the functional DP, thus i am sure the port works.

Is there any reason why the graphics card might not work with some of the ports on a Hackintosh, can you choose or disable specific ports?
Any suggestion to troubleshoot this?

Using High Sierra 10.13.6
i7 7700k
Asus rog strix z270g
rx 580 8g

thanks
