Hi, I'm normally using my old 24" Apple LED Cinema Display without any issues on the Display port directly on my Surface pro 4. Today I got a Surface Dock and it won't work when connected to the display port adapter on the Dock (still working directly on the Surface). I read in the Forum that there are all sorts of issues if one needs to use an adapter, but the display has a native display port cable/Interface so I assume it should work. Does anyone know what I need to do to get this working? Many thanks for your help.
