External display Windows 11 certain programs blurry?

[OnlyAlex]

Hello, has anyone else come across this problem where with an external display plugged into their laptop, and the external monitor set as the main display, that some programs or settings opened and moved across to the laptop monitor is slightly blurry? You can see this highlighted below with the first image being on the external display and the second image taken with reliability monitor on the laptop display with external monitor plugged in on 'extend' setting. Thanks!

What is the make and model of your laptop and external display? How is the external display connected to the laptop? I'd try and use DDU and remove all GPU drivers(both iGPU and discrete) and then manually reinstall with the latest GPU drivers in an elevated command, i.e, Right click installer>Run as Administrator.

What are the respective sizes and resolutions for each of the 2 displays? It does make a difference in perception, as does simply dragging/dropping a window between monitors does not always cause the window to update itself from the previously noted resolution (poor coding in this case).

Thanks. Apparently it’s to do with resolution scaling looking online.

Thanks, it seems to be as you say not all programs being able to handle DPI scaling after looking online.
