Hi,
Basically, I have a Dell G15-5515 laptop, and I am having an issue with my external monitor (screen refresh rate = 165 Hz), where I get very sluggish experience when I use external monitors. Tried proprietary drivers from Nvidia (distro one), and the problem seems to persist among different distros, Pop OS, Ubuntu, Fedora. Up until yesterday, with nouveau drivers + Xorg session manager, everything was work fine, suddenly I can't seem to login in Fedora 41 anymore (upgraded from 40).
Wayland works, but I can't set more than 120 Hz, and even with 120 Hz screen refresh rate, there's noticeable lag, is anyone facing similar issues?
Regards.

Did you try to recover via clean install of Fedora?

What happens if you use X11 + open source nvidia drivers?
Also, could you do ?
Code: 
xrandr > xrandr.txt
And attach xrandr.txt here?

if you get xrandr - no such file or directory
Bash: 
sudo dnf makecache --refresh
sudo dnf -y install xrandr
