Can't get windows 11 to scale down display to 100%

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

 

Hi, kindly help us with the screenshot of the error page to assist you further.

 

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

 

I have same issue, but scale percentage is grey and unable to change as reverts back to 300%

Same here.

 

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!

 

Tried this just now, still doesnt seem to work.

 

Worked for me, thank you, you're a life saver.

 

I wasn't able to get it working either until I found this KB for Parallels 12: https://kb.parallels.com/en/123951

 

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

 

I have an M2 MacBook Pro with Parallels Desktop Pro 19.

 

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

 

Thank you for this. It's the only thing that worked for me (on an M3 MBPro)
