Thank you very much for your help. It is the LG on Displayport or Hdmi that stays black. I have noticed that when in a dual monitor there is a VGA port connected it is always the VGA port that is recognized in both Linux and Window; I think that this is the characteristic of the X86 architecture. I will try to install Wayland. Thanks
