I had the same problem when I went from OS 10.7 on a 2010 MBP to 10.9.1 Mavericks on a Late 2013 MBP but I am running Windows XP. I reinstalled Parallels Tools as shown above but that did not solve the problem. The knowledge base article says:
"Note: The Resolution settings shown on the picture apply to Windows 7 and Windows 8 Virtual Machines. Resolution options are different for Windows XP and Windows Vista Virtual Machines."
How do I fix the resolution options if I am running XP? Or do I have to upgrade to Windows 8? Or should it be 7 or Vista? (I know XP is old, but if it ain't broke...)
