Nvidia-modeset: WARNING: GPU:0: Unable to read EDID for display device LG Electronics W2486 (DP-1)

i have asked a few days ago how to fix a blackscreen problem, currently happens on one of the screens, not always the same and sometimes it is fixed by removing and adding cables but other times it just does not work.

I had sent details on the last reply on this post Black screen, unstable or not second monitor RTX2070, Ubuntu - #20 by bizmate

But I am attaching a new nvdia log

nvidia-bug-report.log.gz (719.7 KB)

I see the log is complaining about some modules being loaded already such as

nvidia-drm' appears to already be loaded in your kernel

and

ERROR: Kernel configuration is invalid

but I have no clue if these might cause the problem or not and what to do next.

The log shows the screens are indeed detected on DP1 and 4 apparently but again why is it causing a black screen?
