Purewrangler is only allowing to use NVIDIA cards as eGPU. Display goes black when connected to eGPU.

Notable is, that SysInfo tells that Apple's adapter is connected, right rez and also display tells all right freqs, but the screen is blank.

....and problem solved!
Somehow nvidia's webdrivers were dropped off.
Installing them again with PW and now I can order 5500 and use my apple-adapter.

Now just to find a nice cheap mechanical dp switch, so I can check easily what's happening in old mini2012...
