HDMI monitor no display after update

General system Newbie
1

I ran yay -Syu and rebooted, and afterwards my montior configuration/arrangement seemed to be reset, and my HDMI monitor no longer seems to be detected (it does not appear in xrandr or the KDE display configuration). I have 2 other connected displayport monitors, and they still work. I am not sure where to begin looking to identify the issue.

Since xrandr does not even list an unconnected hdmi output, I’m wondering if somehow something is wrong on the driver side? GPU is a 9070xt, as far as I can tell everything is working fine otherwise.

xrandr output:

Edited to add:
Unplugging the HDMI cable from the GPU and inserting it into the second HDMI port fixed the issue, and then reinserting it into the new HDMI port works. I probably should have tried that first I suppose. No idea what the root cause is.

Made account to post something similar updated to latest system with yay, now my screen reverted to 1920/1080 instead my old 2056x1080 on top of it when I run xrandr there is also no option of my ultrawide screen. Inside Kde there is no option to change screen either, I tried in both wayland and x11 I have nvidia card

I had a similar problem this morning. I downgraded the nvidia drivers by running sudo downgrade nvidia-open-dkms nvidia-utils and rebooting. I had to select my higher resolution in the display and monitor settings.

sudo downgrade nvidia nvidia-utils lib32-nvidia-utils running and reverting to 580.95.05-1(nvidia-utils lib32-nvidia-utils ) and nvidia itself to 580.95.05-9, seemed to do the trick thank you mate!
