Thank you very much but it's not working :
My resolution is grey.
Sorry

Please let us know if the Windows display is black and white?

Chris28 · Dec 28, 2017

no normal color when I say grey it's that you can't change resolution ("grisé" in French)

Can you please let us know what happens when you try to change the resolution or please share a screenshot so that we can check.

Chris28, It seems there is no Video driver installed in your VM. To do that please use Actions menu and select Install/Reinstall Parallels Tools menu item.

Yes !!!! It Works !!! really Thank you very much and have a nice end of year from FRANCE !!!!

What resolution you set and how? (Inside Windows? By resizing window? In Fullscreen or windowed mode?)

Hello Chris28, please change the resolution to scaled on the virtual machine as suggested in this article and then change the resolution to see if this works. Thanks!
