can't change screen resolution (Windows 10)

[NikoG]

Hi guys,

I installed Windows 10 x64 via Parallels on my Mac Pro 2013 with Mac OS 10.12.4 (Sierra, actual version). In Windows settings I cannot change the screen resolution (it's greyed out) so it's always set on 1024x768. The max. screen resolution is 2560x1440. Connected via Display Port. I tried to switch the full screen modi at Parallel's "Windows 10 Settings - Options - Full Screen" but it doesn't fix it.

I'm still using the trial version of Parallels Desktop. Maybe this is the reason? If I could solve the issue, I'll buy it.

Thanks for your help!
Niko

I have the same problem as described above and i've tried all the steps that has been mentioned in this thread but no success. It's just stuck at 1024x768 and this happened after I upgraded parallels to 13.2

I can't access my macbook over the network anymore either.

When i try the "reinstall parallels tools" step, the screen resolution changes to the correct resolution during the installation but the installation fails at 51% and says that I have to reboot my windows and after reboot the same problem is back.

Hello @SimonB8 If you have Windows Defender on the virtual machine, please disable it and try to install the Parallels Desktop and also, please refer to this article http://kb.parallels.com/8969 and check it helps. Thanks, Shathish

Hi,
Have same problem and none of the above seems to work
Have 2017 iMac with 32gb and running High Sierra.
Have Windows 8.1 to which I upgraded to Windows 10 but the Parallels VM window still says Windows 8.1
(It was working fine on the Windows 8.1)
Have Parallels 10 and upgraded to Parallels 15
Have tried to change the windows resolution but it doesn't seem to work (Using the two RED Bars in Toolbar and changing resolution changes my iMAC which does change the Parallels window but all of my iMAC screen is much smaller. (not the solution obviously)
Have included screen on Windows that says ms-settings:display "This file does not have a program associated with it for performing this action. Please install program or, if one already installed, create an association in the Default Programs control panel."
Not sure how to do this or where or what exactly to install....
Any help appreciated.
