Describe the bug

When connecting an HP LA2206 monitor to a DP output on RTX 3050,
the monitor is not detected correctly. Instead of reading the monitor's EDID, Hyprland reports
it as "Nvidia 0x0000" with a physical size of 0x0mm and only 640x480@59.94Hz available as a
mode. The monitor works correctly when connected to an AMD GPU.

To Reproduce

1. Connect an HP LA2206 monitor to an RTX 3050 DP output
2. Run hyprctl monitors
3. Monitor appears as "Nvidia 0x0000" at 640x480 instead of HP LA2206 at 1920x1080

More Info

ignore HDMI-A-2 since its my third monitor, connected to AMD GPU

Start with the attached nvidia-bug-report.log.gz and reproduce the issue by connecting an HP LA2206 to the RTX 3050 DisplayPort output. Use hyprctl monitors to compare the reported EDID, monitor name, physical size, and available modes with the expected HP LA2206 at 1920x1080; done means the display is detected correctly and the regression is verified.
