Hello I had to reinstall Parallels 13 on my 2015 Mac Powerbook Retina 15:. Now Windows is too small, icons and type. I searched the knowledgebase and it said to got to Configuration/Hardware/Graphics and select 'Scaled' but there is no change. I rebooted Windows several times and it is always tiny now. I also reinstalled the tools but no difference there either. Any suggestions?
