Niestety nic nie pomogło. Niby po zabawach z wpisami w xorg.conf jest prawidłowa rozdzielczość, odświeżanie. Jednak ciągle monitor jest niewyraźny, najmocniej widać to na tekście. Czarne literki przechodzą miejscami w czerwone.
EDIT:
Sprawa okazała się być prostsza niż myślałem. Wystarczyło w ustawieniach monitora wybrać i zatwierdzić dwie opcje: Image Reset i Color Reset. Pomogło

Ale w razie jakby ktoś potrzebował to wklejam mój aktualny xorg.conf
