It seems that my current environment (Arch Linux and KDE) is forcing me to use only the native display resolution and frequency for my laptop. My laptop is a gaming laptop, a Dell G15 with both Intel integrated graphics and an Nvidia RTX 3050m.

This is what KDE outputs:

Display configuration: says "Refresh rate: 120 Hz"

This is what xrandr outputs:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 340mm x 190mm
   1920x1080    120.04*+
DP1 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

I want to lower my refresh rate to 60 Hz, I even tried manually adding it to xrandr using the command line, but, sadly, it did not work.

What is happening here?  It works as expected on the Windows side (I have a dual boot).

On a side note, both nvidia-settings and nvidia-smi refuse to open.  Maybe it's a driver problem?

Try to disable the IGPU in the bios. If you cant use the NVIDIA services, there might be the problem that Linux uses the IGPU instead of the nvidia gpu. I had a similar problem.

-> Terminal freezes for every command regarding the Nvidia graphics card
