I can't get quite the right colors on my external UE590D 4k. Does anyone have the correct settings/colors so it looks as close as possible to the MacBook Pro retina display?
Went round and round on this - now the Samsung is matching my Laptop (MacBook Pro 15 Inch 2018) darned near perfectly.
The trick for me was ditching the U28E590 Profile in Display Settings for the monitor and choosing "Thunderbolt Display". This alone got things very, very close.
Then on the monitor, here are my settings: Brightness: 100 Contrast: 100 (Adjust these two to taste, I like it bright and sharp) Sharpness: 72 Red: 65 Green: 62 Blue: 62 (Setting these three above 50 gave the saturation a boost) Magic Angle: Custom
Hope this helps someone.
