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!

It is related to the interface resolution scaling.

First hit on Google so I don't know how good it is https://pureinfotech.com/fix-display-scaling-issues-windows-10/ but that is probably the problem.

Ah, thanks so much.
