Issue/Bug Description:

I have two monitors, neither of which are recognized correctly with this kernel. (Works fine with 6.8.0-76060800daily20240311-generic). One of the monitors is connected to my graphics card's dvi port and stays all black. The other monitor's resolution is not identified correctly (should be 1920 px × 1080 px, but very noticably a smaller resolution)

Steps to reproduce (if you know):

  1. Boot with kernel linux-image-6.9.3-76060903-generic

Expected behavior:

Both monitors should be recognized as displays with 1920 px × 1080 px resolution each and working correctly

Other Notes:

My graphics card is an MSI Radeon RX 480 GAMING X 8G.

I have collected some more logs and system information. The files with 6.9.3 in the name have been collected when booted with that kernel.
