I am struggling with PD9 and Windows 8.1. It seems that both Parallels and Windows have worked to remove options rather than add them. I am running a 2013 Retina Macbook Pro with external 1900x1200 displays. With previous Windows 8.0 it was impossible to get anything workable as far as resolution goes, so I ran it with scaled 1440x900 for the retina display which would at least make my external displays look better. Now with windows 8.1 and it's new per-display scaling it's a nightmare. There is just no way to get any kind of satisfactory font scaling between the displays. Sometimes a window will have gigantic title bar font and little tiny text inside. Moving a window from one screen to another could cause the text to scramble and become unreadable. Sometimes I have gigantic icons on the desk and a tiny task bar. I gave up and went back to scaled graphics. Are there any settings or tweaks that can improve this?
