drm_info

SUMMARY

I cannot find the resolution of my monitor in the display options.

STEPS TO REPRODUCE
1. Open system settings > display and monitor > resolution

OBSERVED RESULT
There is no resolution higher than 1920x1080.

EXPECTED RESULT
There should be more resolutions available as I am using a monitor capable of 2560x1440@74.97Hz

SOFTWARE/OS VERSIONS
Linux: 6.6.41-1-MANJARO (64-bit)
KDE Plasma Version: 6.0.5
KDE Frameworks Version: 6.4.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION

I have a Philips 245E1 monitor. It doesn’t seem to send the correct edid or something, so it was a struggle to get it to work properly on Linux when I bought it some years ago (I’m currently using Manjaro). In system settings, I can only choose resolutions up to 1920x1080, but it supports a resolution of 2560x1440 at 60 Hz, as I was using it like that on X11 with this custom modeline in /etc/X11/xorg.conf.d/10-monitor.conf
```
Modeline "2560x1440" 241.5 2560 2608 2640 2720 1440 1443 1448 1481 +hsync +vsync
```
However, I want to use wayland and I cannot get it to work. I asked on https://discuss.kde.org/t/enabling-higher-resolution-in-wayland/19410 and maven told me to report a bug here with the following outputs:

`kscreen-doctor -o`
```

The output of `drm_info -j` is 6420 lines long so I guess it's better to attach it as a file.
