Hi,
I've been on this for many hours now, but I'm unable to progress any further.
A little Background:
Two weeks ago, my GTX1070 died, so I decided to buy a new PC and ordered all the parts. CPU, MB, GPU is all new, I'll just keep the peripherals and my two monitors (1080p Samsung, 4k Acer XB280HK).
I've been using my old Hardware for years with Arch for 4k Gaming (nvidia/Xorg) without any relevant issues.
So when my AMDGPU arrived early, I was eager to try it in my old PC until the other parts would arrive. That's were I first encountered the issue. I didn't think much of it, as I would do a clean install anyways and worked around it for the remaining days.
With my new AMDGPU, I also wanted to switch to wayland, bc of UI scaling issues on X with 4k/1080p displays and why wouldn't I do the switch now.
The Issue:
When using my new AMDGPU and Wayland/KDE, I can not select my 4k monitors native res. Only 640*480 is available.
The Workaround:
I can go back to X and use Xrandr to give it a new mode:
[ctms@ceetemus ~]$ xrandr --newmode "3840x2160_60" 533.250 3840 3888 3920 4000 2160 2163 2168 2222 +hsync -vsync
[ctms@ceetemus ~]$ xrandr --addmode DisplayPort-0 3840x2160_60
[ctms@ceetemus ~]$ xrandr --output DisplayPort-0 --mode 3840x2160_60Here is what I've tried (not in that particular order):
1) [OK] boot into windows (second SSD) and confirm my GPU, DP-Cable and Monitor are working properly
2) tried another DP-Cable from my workplace
3) I tried get-edid, but only found my Samsung Syncmaster 1080p@HDMI and my Onkyo-TXNR727 AV-receiver 1080p@HDMI:

4) extracted my monitors EDID.bin from my windows instance and forced it on my DP-connection - as described here: https://www.reddit.com/r/archlinux/comm … e_monitor/
(I did not modify the edid, as there wasn't one on linux and the one from windows looked ok (I wouldn't know what to edit anyways..? It already showed the native res and all the other meta data)

This however makes the DP-Monitor disappear:

Oh wow..
I've found this great resource of EDIDs from users: https://github.com/linuxhw/EDID
I looked up my monitor and got the EDID.txt from the huge archive.
As it turns out, my edid was missing some info compared to the one from the archive -.-
With the command from the git readme
cat EDID.txt | grep -E '^([a-f0-9]{32}|[a-f0-9 ]{47})$' | tr -d '[:space:]' | xxd -r -p > EDID.bin I made the new edid.bin and moved that to /usr/lib/firmare/edid/EDID.bin
mkinitcpio -P
restart
done
Fuck me...
