My second monitor attached to HDMI of my Lenovo V15 is DELL S3422DWG and has
aspect 21:9 with resolution 3440x1440, with supported resfresh at 100Hz.
I could not set native resolution on my second HDMI DELL S3422DWG in any way.
I tried cvt, modeset, passing boot parameters to grub, porting EDID from
Windows 10 to custom EDID with grub parameters.
Every one move ended up with 4k resolution 3840x2160(16:9).
And I saw a lot of similar reports on unresolved 21:9 issue on reddit,
stackoverflow etc.
Kind regards.
