Low-Quality Text Display issue in InDesign on New 4K Monitor

[effiecgu]

replaced 1 of 2 old monitors on a desktop machine (i7, GF1060, win11), with a 4k Dell U3223. 

drivers were installed, color profile seems good.

All ID files look low quality on the new monitor. If I drag them to the old monitor, they look great.

If I copy the text from the file, and paste it into a Word document, it looks great.

Found the setting for ID that shows only medium quality, changed it to high, but it made no change.

tried changing resolutions from 4k to 2k, FHD etc. Also tried different scaling levels (150%, 125, 100) in windows, but nothing helped.  

Mentioning again, everything looked great on the replaced monitor, and still looks great on the remaining older monitor,  and everything looks great on the new monitor outside of ID.

Is ClearType active, and have you updated its settings?

There are a lot of levels to screen display/resolution, especially under Windows, but there's no inherent reason you should have anything but perfectly crisp detail on any monitor. I suggest the change has left behind some low-level setting that's incompatible; you've mentioned the basic ones but CT would be my next guess.

Can you share a screenshot with Type > Show Hidden Characters and View > Extras > Show Frame Edges enabled?

Make sure both the resolution and scale are set to "recommended". 

Can you post screen shots of the difference?
