Maximum resolution and frequency not detected on an ultrawide display

Hello everyone,

I’m having a problem with my Philips Evnia 49M2C8900 monitor, which is stuck at a resolution of 3840x1080 60Hz.
The monitor can handle 5120x1440 240Hz. I have an AMD 7900XTX, which also handles it very well, logically.
It is detected perfectly in Windows 11 (2 cables tested).
I also tested a Manjaro and Ubuntu livecd version to confirm that I didn’t have a weird configuration on my OS.
Could you give me a hand to solve this problem?
