Windows 10: disable DPI scaling by default for all apps

I have Windows 10 DPI set to 150% and many apps are blurry. As you know, this is fixed by disabling DPI scaling per app, but I would like to do that for all apps by default. I am already using the "XPE Windows 10 DPI Fix", but this does not fix it for me. I have researched it extensively and can't seem to find a way to do it. I have a right click context menu item for disable DPI scaling on an executable, but it makes me angry every time I have to do it manually.

Here's an example:

On the left is what I get by default. After changing the setting in the center, I get the result on the right. I want the result on the right without having to disable DPI scaling manually.

The kicker is that I have an older computer which behaves exactly as I want: apps run without being blurry at 150% DPI (the same apps that are blurry on my new computer). That computer is running the release version of Windows 10 from 2015. I tweaked it heavily, disabled updates (not once did I need to update!), etc and it has worked great all this time. I got a new laptop and imaged my wonderfully configured Windows to it, only to find the laptop video driver can only be installed on a newer Windows version (something about switching between Intel and Nvidia on the fly). OK, fine, so I install Windows 10 fresh and I have this blasted DPI scaling problem.

I remember I had DPI scaling problems on my old Windows install when I first got it, but apparently I tweaked something to fix it. I can't remember what I did, though I found chat logs of me complaining about it to a friend (sadly I never mention a solution). It is running the "XPE Windows 10 DPI Fix", maybe that was enough? Any idea why that doesn't work for my newer computer? I don't know if things are different with the latest Windows 10 updates or if there is a tweak I haven't done on the new computer.

Is there a way to force DPI scaling?

Hello,



Thank you for posting your query in Microsoft Community.



Let me answer your query regarding DPI scaling.



Please be informed that you cannot force a DPI scaling on a particular app, right now there is no option to do that. If you have set a custom scaling level to 250% and if the app doesn’t support, to run the app, you have to disable
dpi scaling for that particular app.



You may follow the below steps and check.



1. You may right-click the application’s shortcut and then click Properties.

2. On the Compatibility tab, select “Disable Display Scaling on High DPI Settings” and then click OK.

3. Now check if you can use the application.



Hope the information helps. Do reply if you need further assistance.



Thank you.
