Hi! It is not problem about blurry screen. both external monitor as macbook are fine. the problem is just regarding the background image (wallpaper). On macbook screen wallpaper has lots of details, high resolution.
on dell monitor 24'the image of wallpaper comes pixelated, very low resolution, blurry, ugly, no details, etc... JUST image. the texts, windows, everything keeps fine. JUST image of wallpaper is very poor.
I will tray to explain in other way:
it is like that:
when i set an image of wallpaper on macbook screen, it is like an image with 4k resolution. the same image, on dell monitor 24' is like a 800x600 resolution in big screen.
can you understand?
it happens with all the default wallpapers that comes in mac, even dynamics.
i only can see high resolution on dell 24', if i download other wallpaper on internet with 4k and set as static.
but i want to use default wallpapers of mac, dynamic ones, however they are vey bad on dell...... could i be clear?
It is not problem with monitor dell, because it is very sharp. it is only the quality of background/wallpapers.
I think it appears being problem with OS system, bug.... however, it happens both with big sur as monterey.
I found this: (same situation)

before the migration to apple, when i used windows, the same dell monitor always was very sharp with default windows wallpapers. but with mac it is garbage!
