We discovered when using Samsung monitors, there will be a slight discoloration having that FreeSync is toggled off by default.

In this case, we recommend turning FreeSync on to see if this remedies the display issues you are experiencing.

These settings can normally be found in the Game Mode settings or the refresh rate settings on your monitor.

FreeSync is an adaptive synchronization feature found in many new TVs, including those from Samsung. The technology enables more accurate color and brightness levels and is compatible with Macs, PCs, and gaming consoles

In addition, we recommend checking the color profile with the connected monitor(s) 

System Preferences/Settings > Display > Color Profile (deselect then reselect)
