    Hi PatrickP3, please follow the instructions mentioned below to fix the issue:
    1. Start Parallels Desktop.
    2. Go to your virtual machine's Configuration > Options tab > Full Screen.
    3. From the Scale to fit screen drop-down list choose Keep ratio:
    4. Start your virtual machine in Full Screen mode.
    5. Go to Start > Control Panel > Display > Change display settings or just right-click on Windows Desktop and choose Screen Resolution:
    6. Set the screen resolution to the preferred values.
    7. Restart Windows. Screen resolution in Windows will remain according to settings you made.
    Note: since Windows and Mac screen resolutions do not match any more, you may see black bars on top-bottom or left-right sides of Windows screen:
    In order to avoid that, you may want to force Windows screen to get stretched to fill all Mac screen:
    Go to your virtual machine's Configuration > Full Screen
    From the Scale to fit screen drop-down list, choose Stretch
    Note: in this case your custom screen resolution will be kept, however, all objects and fonts in Windows will be stretched.

    I have done the above and can't change the resolution. It's locked out on the VM. Note, the VM starts up with the correct resolution but once I login, it shrinks down on the sides.

    Thanks to this helpful advice I was able to learn why black boarders showed on the top and bottom of my Parallel Windows display, as stated by Paul "since Windows and Mac screen resolutions do not match any more..."
