[SOLVED] My second monitor is detected, but it remains black.

I'm pretty new to Linux and I've installed Arch recently with KDE Plasma. My second monitor didn't light up, when I booted, I checked the Display settings and found out that both monitors are detected as they would work smoothly and I can even interact with workspace of the second screen, but I can't see it, cuz my second monitor just remains black.

That's really confusing me, because I've tried Ubuntu(Gnome3) and Debian(Cinnamon) distros before and there was no problems with my second monitors. I didn't use KDE Plasma or Arch-like distros before tho, but I'd like to keep it if it's possible.

I've tried:
* reinstalling Arch (None result)
* configing it with xrandr (None result)
* adding amdgpu.dc=0 parameter to the booter (None result)
* Changing from NVidia to Neavou (It broke everything even more as it couldn't even detect the monitor or set a correct resolution, so I decided to install NVidia back)

Info, that might be usefull:
* My GPU: NVIDIA GeForce RTX 2060 SUPER
* My Kernel: 6.12.1-arch1-1
* My DE: Plasma 6.2.4

My Monitors:
* Both's resolution is 1920x1080
* Both has HDMI cable, but I had just one HDMI input, so the second monitor is connected with HDMI-to-DVI port

My xrandr output:

Lower the refresh rate manually.

Re: [SOLVED] My second monitor is detected, but it remains black.

Borked DVI input is a known upstream issue with the nvidia package https://gitlab.archlinux.org/archlinux/ … /issues/10

A new version was recently released that should fix the issue, until then you'll have to downgrade or live with it
