How to change display refresh rate from 144Hz to 60Hz?

Get into BIOS and look for some relevant setting. It could be controlled/locked from a BIOS setting :person_shrugging:

There isnā€™t any.

Might be worth mentioning, that setting 60Hz works on a system where I donā€™t have NVIDIA drivers installed. Using nouveau wll allow me to choose any framerate I wish. So I think itā€™s something to do with the NVIDIA drivers.

Now, how and if this helps me I cannot say.

Switch the display to Intel and then try switching to 60 Hz.

Look into your laptop user manual. It is a hardware related issue. Any hardware or firmware info, specifications could be helpful.

I agree that nvidia settings could have some configuration, but itā€™s you who has to try them :person_shrugging:

The funny thing is that usually users try to raise than lower monitor frequencyā€¦ :smile:

From what I found some models support switching the refresh rate with the key combo Fn+R.
If this is not working it looks like you need third party software. There is something called CRU (Custom Resolution Utility) but itā€™s just for Windows. No idea if thereā€™s anything like this for Linux.
