Hi Sebastien, Thanks for getting back to me. It's an issue that appeared many releases ago related to a kernel update that unfortunately has not gotten any attention. I will try to find some data on that and post it here.
The end user effectively cannot select the 3440x1440 resolution in gnome-settings because it is ot present. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1825665 Title: Cannot set 3440x1440 resolution for HP 34C external monitor (HDMI) on ubuntu-wayland Status in gnome-control-center package in Ubuntu: Incomplete Bug description: On the regular Ubuntu desktop I use an .xprofile with xrandr commands that add the monitors native resolution as follows: xrandr --newmode "3440x1440" 196.25 3440 3600 3952 4464 1440 1443 1453 1468 -hsync +vsync xrandr --addmode HDMI-1 "3440x1440" Unfortunately this doesn't work under wayland and I have not yet found a solution. I have tried several ideas including a custom edid bin file without success. I'm reporting against the gnome-control-center since this corresponds to the end user experience.
