For me the issue is with M1 macbook pro and this seems to help a bit: https://ahmadawais.com/fix-macos-mojave-font-rendering-issue/
suggests putting the following in terminal: defaults write -g CGFontRenderingFontSmoothingDisabled -bool FALSE
which apparently re-enables font smoothing.
Also (for my m1 and monitor combination) purchasing a usb-c to 8k displayport cabl
e helped a bit.
Last, but not least, on my LG LG 35WN65C-B 35'' Curved UltraWide QHD the following seemed to have an impact:
Picture->Picture Adjust->Super Resolution+->Off
Picture->Picture Adjust->DFC Off (not sure if this makes a big difference with font smoothing enabled, seemed to matter more before then)
General->SMART ENERGY SAVINGS->Off(not sure if this makes a big difference with font smoothing enabled, seemed to matter more before then)
It's better, but honestly I think it still looks pretty meh.
This is particularly annoying since:
- Apple said they would fix this in 2020 and still has not
- Windows fonts looks quite lovely on the same monitor (I suspect linux does too)
- We have a 5k intel Imac that would be perfect as a monitor while when we replace it with apple silicon except Apple no longer allows it to be used as an external monitor.
I will likely return the ultrawide, get a more compact (and for some reason more expensive) 4k (24" or 27"), and nurture a simmering frustration towards apple product management at the stupidity of some of their decisions.
Anyway, I hope the above helps someone
