No proper resolution for Philips 272G5DYEB on Ubuntu 20.04
I'm currently (in Ubuntu 20.04) stuck with this low resolution: 640x480 59.94*, what I want to have is the monitor specs: 1080p and 144 Hz. This problem appeared after plugging in my old monitor after 2 years again, it's a Philips 272G5DYEB. Things that I unsuccesfully tried to get a proper resolution:
- Use different systems: desktop and laptop with GPUs from different companies: 1050 ti (mobile) and 5700 xt
- Use different drivers: propritary and open source
- Change resolution via xrandr addmode/newmode with modelines from cvt 1920 1080 and modeline I got from Windows (where 1920x1080 works) (leads to monitor saying "no signal on screen")
- Using "GRUB_GFXMODE" config in grub (no change)
- Searching through logs, only useleful thing I found was in the Xorg log (for AMD):

- In Windows the resolution works, but Windows is showing resolutions up to 4K which is unusual (I think). Looks to me that Windows is guessing the modelines better
- Both GPUs work fine with a different monitor
- Use latest DRM-tip kernel
- Use different DP cables
