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?
Here are the settings I'm using that's pretty similar.
Picture Samsung Magic Bright > Custom Brightness - 22 Contrast - 75 Sharpness - 76
Color Red 69, Green 52, Blue 60 Color Tone - Custom Gamma - Mode 3 (edited)
For this particular Samsung monitor setting the Samsung Magic Angle (Menu > Picture) to Standing Mode and having a low brightness (22) did the trick I have the exact same colors as on the Macbook Pro Retina.
