    I'm using parallels 12 and have just installed windows 10. Everything is working perfectly except for the screen resolution. The resolution is stuck at 1024x768 and the option to change it is grayed out. The display driver is showing as 'Microsoft basic display driver' and my monitor is showing as a generic non-PnP monitor. What do I have to do to fix this problem as currently it just looks terrible. i am using a macbook pro retina 2015

    Hello John, please follow the below steps and keep us updated on your progress:
    1. Start Parallels Desktop ( Do not start Windows Virtual Machine )
    2. Go to Virtual Machine configuration > Options tab > Full Screen > From the Scale to fit screen drop-down list choose Keep ratio.
    3. Follow the steps as suggested in the article.

    Hello, I'm experiencing the same issues. I have put my settings to scaled and keep ratio. However, I am not able to change the resolution in Windows 10. Furthermore, I have tried to reinstall the Parallels Toolbox, which could not solve the problem either. The display driver and monitor have got the names that JohnM31 has also seen.

    Hi, did you mean Parallels Tools?

    Oh, I'm a fool! I've just realized that I had installed Parallels Toolbox instead of Parallels Tools (not knowing that those are two different things). Thus, nothing worked like it should. Now the system works perfectly! Thanks a lot :D
