Recently I bought a 4K monitor (AOC U27U2) and after connect my Dell Vostro 3500 I was unable to set 2560x1440 or 3840x2160 via xrand (X11 windowing system). I Always get "xrandr: Configure crtc 0 failed" error. I already tried the wayland windowing system but the problem is the same. My HDMI cable is 2.1 and the graphics card is Mesa Intel® Xe Graphics (TGL GT2).
