I just bought a new PC (components are listed below) and connected it to my Samsung U28D590 (28" 3840x2160) using DP1.2 but the maximum resolution I can set is 2560x1440.
The latest drivers for all components are installed and I also tried different cables (all DP) but it won't let me change the resolution to the screen's native resolution.
Intel i5 8400
16 GB DDR4 @2666
Samsung SSD 960 EVO 250GB M.2

thanks for your quick reply.
After testing some other displays I am sure that this Samsung display is broken somehow.
I tested with a few other Samsung displays of that model and all others are working fine.
This thread can be closed as my problem is solved now.
Thank you anyway for your help!
