I work in the classroom with my notebook, to which I have connected a beamer. Sometimes I write things down in the Writer and show it via the beamer. I would like to use the fullscreen mode here. Unfortunately, the fullscreen mode is always displayed on the internal monitor, even if the window with the Writer maximized was previously displayed on the beamer.
