I recently installed EndeavourOS on my pc and can’t seem to get the disply to run at 75hz there is not option from me to even set it at 75hz it did run at 75hz when I was running CashyOS.
I have tried “lxrandr” also tried changing the display manager and switching from wayland to x11 and back no luck for me.
I have a nvidia GTX 1080ti and the driver is installed.
Please let me know if you need anymore info from me.

nothing there shows that 75hz is supported
you could try just running xrandr and setting the rate however according to the query its not supported.
I’m not sure if you still have cachy installed, maybe it was using a different driver
this article might help, maybe you were loading a different driver version https://www.cyberciti.biz/faq/linux-check-version-of-ko-kernel-module-driver/
Hello @Dreadside!
Would it be possible to tell us the model of the monitor? So far, we only know that it is from Dell, can run at 60Hz (75Hz?) at 1920x1080 and is connected to the Nvidia GTX 1080 Ti via HDMI.
Hi sure it’s a Dell S2721HN I know it does support 75hz because it is even on the specs page and box only thing is that it does not want to run that on endeavour but does on Windows and Cashyos as stated so must be a setting some where or package that need to be installed I’m guessing.
Thank you very much. Could you please post the output of inxi -Fxxc0z?
Edit: According to the arch wiki, the normal Nvidia driver should be used (your GPU is Pascal) .
This is a known bug in the Nvidia driver version 580.105.08-1, I’m experiencing the same issue. You have two options: either stick to 60 Hz for now, or downgrade to 580.95.05 and wait for a fix to be released. Cheers.
Thank you!
Thanks for all the replies and help! I really appreciate it.
