Multi-monitor not working after update with nvidia 550 drivers

Hi, I have been facing the same issue with fedora 41. Initially when I updated from fedora 40 to fedora 41, it was working perfectly fine. Now after another update to the latest version, it is not working. My external monitor is not being detected. Could someone please help me out?

This is my xrandr output:

This seems likely to be your problem. That is a relatively old version of the nvidia driver as we are now up to 565.77 from the rpmfusion repo.

Please show us the output of dnf list --installed \*nvidia\* and dnf repolist

Note that I moved your issue to a new thread. The OP on the other thread had a mechanical issue that had been solved. Your issue seems to be software so it is not the same. A new thread was required.
