I have a new MBP 2019 16" with the AMD Radeon Pro 5500M 8 GB vid card.
When I plugged my LG UltraFine 5K display in via USB-C I noticed strange light blue aliasing around font and images.
It doesn't show up great here, but its very obvious to the naked eye.
What is strange is I do NOT see this issue if I change the display resolution scale to
2560x1440 or below in Display Settings:
I know it is NOT a problem with the external monitor, because when I plug it into my late 2018 15" MBP I do not see the problem.
I have a second 4K LG monitor plugged in at the same time, and it is not exhibiting this issue (no matter what resolution scale is selected).
- Disabling font smoothing
- Changing monitor color profiles
- Using f.lux
- Only plugging in the UltraFine 5k
Any ideas what this is called or how I might fix? This is SUPER annoying.
