Public bug reported:

This particular bug I am reporting is killing me from a few years ago,
with every Linux distribution (so, from the removal of xorg.conf). Now
that I have two computers, I can say I did find out the problem.

My monitor is a 17" Hansol H750 LCD, and I cannot use any Linux
distribution without having my monitor say "out of range".

I did find out the monitor is reporting a wrong maximum frequency: vfreq 333.176Hz, hfreq 355.166kHz - whilst its maximum is a 70-75 Hz.
I am going to attach the output of get-edid (parsed), ddcprobe, and the xorg.conf that solved everything.

I am at your complete disposal to solve this particular bug.
