I can't reach 4k 120Hz using DP kabel 1.4 (32Gbps) paired with MSI RX470 4GB Gaming X. When my monitor is in DP 1.2 mode I have just 4k 60Hz, but when I change is to DP 1.4 my monitor (in monitor settings) turns off/ goes black screen. I have tried 2 cables, the one Samsung gave me with monitor and new one to compare. When I'm in DP 1.2 mode my GPU bandwith is 5.4Gpbs and i can't change it.
Monitor works fine with HDMI 2.1 while using PS5 (4k 120hz or 1080p 120hz depends of a game).
Monitor model: Samsung LS28AG700NUXEN
Is there anything left to do to fix it or it is just GPU thing ?
