I ran into the same problem as TFA in 2017 with an AOC g2460pf monitor. The display port would advertise binary garbage for the EDID that wouldn't checksum, so no OS would try and use it. AOC registered some "drivers" with Windows, so it would automatically download and apply a patch that would make that port usable, but they also included a CD with the stuff on it.
However they patched this on the Windows side was quite fragile, because it kept breaking after OS updates. After I could no longer get it working with the reinstall and pray method, I switched to Linux because of this issue. I fixed it once with an EDID in the initramfs, and haven't had any issues for the last 6 years.
