Hello,
I can't seem to set the resolution of a dual screen (4k and FHD) correctly in the framebuffer. I mean, even if I try to put a kernel parameter in loader entries, the best I can get is an ugly FHD on a 4K screen or an FHD that only fills a quarter of the larger screen.
I am using AMD Vega 64 (amdgpu) and systemd-boot config (I also tried with grub).
/boot/loader/entries/arch-lts.conf kernel parameters line and result :
options root="PARTUUID=****" rw systemd.show_status=yes video=HDMI-A-3:1920x1080 video=DP-1:3840x2160

/boot/loader/loader.conf
default arch-lts.conf
timeout 0
console-mode 2
editor no
Amdgpu module set on mkinicpio.conf
MODULES=(amdgpu)
Is it possible to set properly different resolution on each screen and rotate one of them ?
Thank you.

You mean you want a multiscreen setup where the framebuffer console displays different things on different outputs like on X11 or wayland compositors?
