Ever since PD12, I can no longer get my Windows 10 guest to display properly on my retinal MacBook Pro. I enabled retina resolution in the video settings reinstalled tools and was finally able to select the correct native resolution of the MB Pro. Now in the display properties, it is showing a custom size of text at 250% and the slider is greyed out. If I click the link to turn off custom scaling and log out, the guest logs out and when I return to the same screen, I see the same exact thing. The slider is still greyed out and the only option is to do the exact same thing again. Has anyone else see this and been able to get around it? I did not have the issue under PD11.
I finally gave up and changes the Parallels view to "best for external displays". After logging out/in, it looked perfect on the retina screen before I could move it to the external monitor. Seems like some lines of code got switched around in v12...
Thanks! I had the same problem on my MacBook pro retina when I upgraded to PD12. Custom scaling was stuck on. Switched the view to "best for external displays" and now its fine. Thank you!
