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.
No sorry, I don't use Coherence, so I don't know. I overlooked the fact that the original poster was using it.
