Blurred characters

I’m using LO Version: (x64)
OS: Windows 10.0 Build 19041
Computer Intel NUC8i3beh
Graphic pocessor Intel® Iris® Plus Graphics 655 (4k UHD standard)
Screen: BENQ PD2700U, 27" UHD

The display setting in Windows are: Resolution 3840 x 2160; Scale (Recommended) 150%

I changed the scaling factor, just to try what it gives, then I set it back to 150%. Since then the characters in LibreOffice Write are blurred, and I don’t know what to do to have them a crispy as they were before. I didn’t try the other components of LibreOffice.

I’d be grateful, if somebody has an idea of what I should do.


Could you, please, comment your question and confirm that this behaviour is only observed with LO and provide the font name ?

Kind regards, Michel
