Like I said. I used to have that problem. I don't know if it was a problem with
the edid the screen sent or something with the xserver / nvidia driver, etc.

I used to need the linked approach to create a custom edid file. Currently
everything works fine on my laptop, so there was some software bug along the
way that nouveau doesn't suffer from and nvidia does.

Unfortunately it was a long time ago so I can't recall what of all things fixed
the issue.
