Question Blurry font on high-DPI monitors

[DeepSpace]

I already noticed it on a laptop that has 1080p on a small screen (=high pixel density) and now again on my new monitor for my PC.
The font that the AnyDVD installer uses, some system messages etc, is blurry. What font is it and (SegoeUI?) is there a way to fix it? I know it's possible to replace fonts, but I don't know what exact font this is and the tweaker tells me that not all apps might support the change.
It is only this specific font, the font in my browser (like this text) and the window title ("Installer Language", "AnyDVD Setup" is perfectly clear. I think I already tried the cleartype stuff on the laptop but it didn't change anything, but I am not sure anymore as it was long time ago.

Scaling ... set it to 100%, log off to apply the changes to non-Microsoft Apps, log on and try again

Edit:
150%


100%


Use glasses or a lower resolution, if it's to small ...

I see, maybe the automatic jump to 150% when plugging in the monitor did not work properly, so when I go back to 100% and set it to 175% again it might work better. I will try it, but I am not sure tbh.
