Dysfunctional DisplayPort #333

What is the precise OS version on which the bug is occurring?
10.15.7 Release (19H15), 11.7.10 according to recovery (Build number: HDMI output is garbled), 12.7.4 Release (21H1123)

Describe the unexpected behaviour in detail.
I installed the latest MacOS Catalina, Big Sur and Monterey, plugged in my monitor through DisplayPort, and my computer turned on, but it didn't display anything, and my monitor showed No Signal. I shutdown, plugged into HDMI, and it showed the login screen. I have tried adding -NRedDPDelay to boot-args.
EDIT: I must note, it did work on Sonoma 14.4.1, on an older version maybe?
What should've happened instead?
I install the latest MacOS Catalina or Big Sur or Monterey, plug in my monitor through DisplayPort, my computer turns on, and it displays the login screen.
Attach any logs related to this issue. For example .gpuRestart, .panic, etc files.
EDIT: I managed to find a .spin file that comes every time I boot with DisplayPort on Catalina (I wasn't sure if it was from my many times attempting to install), but I'm not sure how relevant it is so it's an edit, not a comment.
