    Using Display Settings I try to turn off custom scaling and sign out, but the old scale of 250% returns. I try to manually set it to 100% and sign out, but it doesn't stick. Dialog boxes, etc. are TOO BIG. Running a Viewsonic VP3881 monitor (3840 x 1600), parallels 17.1.1, windows 11

    I had an issue with greyed out Scale section and it was locked at 175% after I've tried to set a custom scaling. To fix this I edited registry.
    1. Hit Windows + R, type regedit and hit Enter to run Registry Editor
    2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop
    3. Look for LogPixels and double-click it
    4. Change value type to decimal and enter value 96 (this equals to 100% scale). Click OK
    5. Next, look for Win8DpiScaling and double-click it
    6. Set value to 0. Click OK
    7. Close Registry Editor. Sign out and sign back to see changer.

    After I did that Scale was not greyed out for me anymore and I cloud change it!

    there is no "error page". It simply remains at 250% scale after I sign out and sign back in. The change does not "stick"

    Thanks; if you have an older version that will work. But in newer versions do not have that option, at least as far as I can tell. For instance, I'm on 19, there are no hardware graphics options.

    I was mistaken on the version of Parallels installed on my machine. It's Parallels 19 (just purchased it a few weeks ago). Here's the setting that I changed (Scaled in this case) that worked okay. I did find I needed to play with the resolution on the VM afterwards for it to work with 100% scaling.

    Hopefully this helps.

    Do you have the intel or apple CPU? I have an M1 MacBook Pro and I have no options under graphics w/ Parallels 19, so that could be my confusion.
    Thanks, Mark

    Well, the KB article I found is neat, but it's still not the same as the graphics menu you have.
