Orange Pi 5 Max & KDE: Says only refresh rate available is 59.95hz

Hi friends, I am brand new to Fedora, as I am an Orange Pi 5 Max owner and didn’t know there was an ARM compatible branch!

Sadly the one glaring problem I can see right off the bat that isn’t there in the other distros I use & have installed, is that there is no option to choose my actual refresh rate which is 144hz (or its reported as 143.something if I recall correctly) anyhow, it’s locked to only 59 which is not so pleasant for my monitor

Is there any steps I can take to fix this?

The monitor is a Dell S2721DGF

Thank you!

I have several other working distros on this device that provide my actual proper refresh rates (other arm-based linux distros that aren’t Fedora) so this is certainly something that has been figured out and works normally

If you want me to provide any output from a working distro as well just let me know which commands to issue and I can happily provide those as well

Thanks again

It seems that the EDID from the monitor on the cable you are using does not support 144Hz with the GPU you have.

I do not know why other distros provide the 144Hz.

You can check on the edid with a command like:

sudo dnf install edid-decode
edid-decode </sys/class/drm/card0-VGA-1/edid

Look in /sys/class/drm for your card and HDMI folder.

The monitor is a Dell S2721DGF, several years old and one of the most popular monitors in North America I’d think at this point.. It should offer 60hz, 120hz, and 144hz (even up to 165hz with DisplayPort but I don’t use that at the moment)

In my other distros they all offer me the selection of 60hz, 120hz, and 144hz so this seems to just be a Fedora thing for now

Here is the output of that command, thank you again for your help.

If you need any other output from another distro that has the monitor working correctly just let me know as well.

I had to exit Fedora again because it’s too unpleasant at 60hz, so I am back in my regular desktop environment again and ran a few commands in case they help:

The EDID looks good and indeed, as you knew, reports a 144Hz mode.
That suggests that it is a issue with the GPU driver.

It would be interesting to compare the inxi -G for Fedora and the working distro.

Also which kernel are you using when you have a 144Hz display?
Who provides that kernel?
