I have one macbook pro retina 15 inch 2013 with external thunderbolt display
i use boot camp direct boot and also from my mac via parallels

i use multiple monitor

i try set TRUE resolution for resolution of monitors for my internal macbook retina and also my thunderbolt display

i test it with all different setting of option->options->Full screen->scale to fit screen modes
but for all modes i have problem with setting NATIVE TRUE Resolution of my display

for example parallels set my thunderbolt display to 5120*2880 ! or for some setting set to 2880*1880 (same as my retina !) in default

changing it to true value reset automatically after reset or logout my VM or change to coherence mode !

but you knowing the default maximum resolution of Thunderbolt display is 2560*1440

i have also some same problem with retina is some setting







PD9 lastest version in osx 10.9.1
guest os :windows 7
mac: MacBook Pro retina 15" 2013
 
I too had some issues getting my resolutions working correctly so that windows were scaled the same on both my MBP display and my external display.

My setup is:
  • An external Dell 2560x1440 as my primary display
  • The built-in 2017 MacBook Pro Retina Display 3360x2100 as my secondary display
I took notes on how I did it; here they are in case it helps anyone:
  • In Parallels configuration for the VM:
    • Set Hardware -> Graphics -> resolution to Scaled
    • Set Options -> Fullscreen -> Advanced -> Scale to Fit Screen to Off
  • In Windows 10 guest OS control panel for displays:
    • Change scaling of both displays to 100%
    • Set external display to 2560x1440 (which is the native resolution for that display)
    • Set MacBook display to 1680x1050 (which is half the native resolution for the display)
Hope that helps.
