@caganimo123 said in Changing refresh rate manually?:

Can I decouple refresh rate and resolutions and pick them individually? Like 3440x1440 @60Hz

I wonder if you can set a custom mode in /boot/config.txt, something like:

hdmi_cvt=3440 1440 60 6 hdmi_group=2 hdmi_mode=87

If that doesn't work, then I would probably look at booting the Pi from a Raspberry Pi OS card and inspecting the monitor's EDID. From there you may be able to get the raw timings for a custom mode using hdmi_timings=

See

Which values are valid for my monitor? hdmi_timings

@zing , thank you. Good to hear it's not just me. I can't comment on that topic you linked as I don't have an account there.

@Secamfr that's it, thanks!

@marcus_972 Merci infiniment pour le partage.

Je viens d'essayer, sans succès malheureusement.
je vais crée un poste dédié, encore merci.

Sorry, my bad. I'll be using that menu a lot now.   ...no offense intended, but if old topics are b*mped it's usually because the online documentation isn't complete. Or perhaps the various languages and forums are detracting from search engine results?

Hi, Could be, but must be done for emulationstation directly on Aloshi repository : https://github.com/Aloshi/EmulationStation
