Windows 10 DPI scalling issues, solutions?

[RazenGear]

Hey lads and gals,

So a few weeks ago I finally bought a 1440p ultrawide and have now run into a problem I experienced before. Apparently, the text in some applications becomes extremely blurry when Windows text and UI scaling is set to 125%, the easy solution to this problem on my laptop was to set a custom scale factor at 124% or 126%. My problem now is that I'm using my old 1080p monitor as a second display and its UI gets zoomed in beyond reason since that custom scale factor gets applied to ALL monitors.

 

Solutions I found:

-Manually changing high DPI settings for each blurry app to Application controlled.

-Going somewhere in the middle with the custom scale factor, for example, 112% for me personally.

-Getting another 1440p display. (I borrowed one from a friend to test this, but buying another 1440p monitor just so my text isn't blurry and my UI blown is too expensive of an option for me)

 

Solution that maybe works?:

Within the options of the NVIDIA Control Panel under the Manage 3D settings, I found an option named DSR - Factors also know as Dynamic Super Resolution, setting this to 1.78x allowed me to make Windows think my second monitor is running 1440p? (not entirely sure how this works) I also set DSR - Smoothness to 27% as 33% seemed a bit too blurry to me. I was now able to set a custom scale factor of 124% and the UI isn't blown up anymore and the before mentioned blurry looking text in some apps is gone. I also noticed that within the Windows Display Settings the Rearrange your displays thing now showed my monitors being the same size instead of a small and big box. nice little extra I guess because now I get a seamless transition between the displays instead of an invisible wall at the top and bottom.

 

Update 4/23/2021:

I installed XPExplorer - Windows 10 DPI Fix and set it to Use Windows 8.1 DPI Scaling, with this now enabled and the DPI Scale: at 125% everything looks sharp, i orignally didn't use this fix as it would zoom in my second monitors UI. but now that I combined it with the above mentioned DSR I have the right desktop icon size, no blurry text, and correct scaling on my UI.

 

If there is a way to set a custom scale factor per display instead of globally or an entirely different solution please tell me below, this entire thing is pretty annoying and i prefer a proper solution but so far haven't found anything that works well.

Hello, if I remember correctly this type of scaling issue only happens when you don't use a whole number multiplier, such as 1.5x (150%) or 2x (200%) on the windows display settings. It's super annoying on my 1080p laptop which requires 125% for me to see anything...

 

You should try setting it to 125%, then logging out of your user account then back in (this fixed most blurry text for me), but some installation dialogues will still be blurry for some reason.

As mentioned in the post above, 125% and most uneven numbers cause this blurry behavior to appear. the solution would indeed be to drop the scalling to an even number but with multiple displays extreme UI zooming appears. which renders that solution completely useless for my use case.

EDIT: moved picture into the post.

 

This is a picture showing what the size problem looks like. problem being that i don't want that 124% to be forced on to the second display.
