Max resolution is 2560x1440 instead of 4k (UHD630)

Hi there,

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

AsRock Z370M-ITX/ac

16 GB DDR4 @2666

Samsung SSD 960 EVO 250GB M.2

I'm looking forward to your replies.

Hey Antony,

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!
