OK. Accept my apolgies - it seems to WORK on 4.8.6. I have just tried it and
after using a VGA connector, I have an output on external screen (my external
connector is connected through DP2 graphics output). The only thing is that I
have only resolutions up to 1024x768, nothing higher. It may be caused by my
DP-to-VGA adapter, I'll have to borrow another one and try.

Anyway - Philippe Dosch, try 4.8.6 if you can. Maybe it will also fix your
problem.
