Mich irritiert, daß bei "... timings supported:" die maximale Auflösung 1920x1200@60Hz beträgt, während danach unter "Detailed mode:" von 2560x1440 die Rede ist, aber an Ende der EDID-Daten wieder maximal 1920x1080 steht.

Xorg meldet zuerst

[    10.155] (II) modeset(0): Not using default mode "3840x2160" (bad mode clock/interlace/doublescan)
[    10.155] (II) modeset(0): Not using default mode "2560x1440" (bad mode clock/interlace/doublescan)

und dann:

[    10.157] (II) modeset(0): Output DP-1 using initial mode 2560x1440 +0+0
[    10.157] (II) modeset(0): Output HDMI-1 using initial mode 3840x2160 +2560+0

Es gibt aber weder Warnungen noch Fehlermeldungen, und diese Konstellation ist für mich Neuland.

Du kannst gegebenenfalls versuchen, ob es mit einer Datei /etc/X11/xorg.conf.d/20-amdgpu.conf und dem Inhalt

Section "Device"
    Identifier "AMD Graphics"
    Driver "amdgpu"
EndSection

besser funktioniert (sofern die Datei /usr/lib64/xorg/modules/drivers/amdgpu_drv.so vorhanden ist).
