I take it this has worked for you? Would you happen to have a configuration I could copy? I have used their recommendation for 2060p: hdmi_drive=1 hdmi_group=1 hdmi_mode=95 as well as putting my monitor timings directly into config.txt: hdmi_drive=1 hdmi_group=2 hdmi_mode=87 hdmi_timings=3840 1 176 88 296 2160 1 8 10 72 0 0 0 30 0 297000000 3 But in both cases, Xorg remains blithely ignorant of 4K. Also, I have already added lines to my Xorg config about the monitor timings, to no avail. They worked under Debian (on a RockPro64 I'm trying to replace), which is a similar version of Xorg. - Jamie
