3rd monitor black like sleep mode while shown in xrandr

Hello community,

I am new to arch and installed it yesterday.
Kernel: 6.6.63-1-lts
Plasma 6.2.3
My setup uses 3 monitors, 2 are connected with a kvm switch and 1 is connected with hdmi (monitor) to dvi (pc).
The 3rd "single" one (HDMI-A-1) stays black with message no input signal, while it is shown as connected in xrandr.
I use a AMD Ryzen 7 3700X with a Nvidia GeForce RTX 2700

Can somebody help me out, what kind of research I can do further or what kind of configuration I can try.
I tried to find a solution by using google an searching here, but I still don't get it.
Thank in advance guys

There is a known issue about DVI not working in the current nvidia release which should be resolved with the next nvidia version: https://gitlab.archlinux.org/archlinux/ … /issues/10
