Hi! I'm running Windows 10 in Parallels on my MacBook Pro Retina screen. At work I have an extra display connected through HDMI. When ever I "dock" at work connecting my MacBook to the display I will have to login and logout on my virtual machine in order to change from "Best for Retina" to "Scaled". And when I disconnect the external display I have to go through the steps again. So there are two annoying steps here. 1. I have to actually go in the to settings of the VM to toggle Display mode between "Best for Retina"/"Scaled" 2. Windows requires me to logout and in again in order for that change to take effect in windows. This is extra annoying since it is really not necessary. IF I have a program running in Windows that blocks the logout call (for instance an unsaved document in Visual Studio) and when prompted by Windows that these programs are blocking the logout would you like to logout anyway or cancel logot, if I choose cancel logout, the display is still updated and switched to the correct resolution really having to logout. So, is there a way of avoiding these steps? Ideally one would like Parallels to automatically do the swiching and with some magic in the parallels tools installed in Windows reset the screen resolution without having to login/logout. Or am I doing it wrong?
Hi Dennis, You need to shut down virtual machine( not to quit Parallels Desktop) and there is no way to apply the changes without rebooting your virtual machine. After applying the solution above all Windows-based programs will be displayed properly in 1:1 scale ratio - everything will be on its position. The only minor inconveniece you may notice is the quality of fonts in Windows - the result of running Windows on Apple Retina display.
