Here is my versions. Mac: 2013 late mackbook pro retina 2.6Ghz OS: 10.9.3 Parallels: 9.0.24229 Display: Dell 32" UP3214Q (3840x2160@60hz) First of all, this is what I want to do - mac: 3008x1692 (HiDPI) - windows: 3840x2160 When I set mac resolution as 3840x2160 and change windows resolution to 3840x2160, it displays perfectly. (clear.jpg) Then I set mac resolution as 3008x1692 (HiDPI) and change windows resolution to 3840x2160, it displays text blury. (blury.jpg) There are three option in parallels (scaled, best for retina, more space) but non of them makes 3840x2160 res clearly. Is my desired setting possible?
