I suspect the subject line is making reference to the horizontal and
vertical refresh rates and other params like dot clock...
On older monitors these values were documented by the vendor.
X11 set up tables have collections of these matched to vendor part numbers.
The xorg.conf file will have them in the Monitor description section.
New monitors have data wires that permit the system driver to look up the
vendor data. Google/ search wikipedia for: "the Display Data Channel
(DDC) and the Extended Display Identification Data (EDID), which
allows computers to communicate with different monitor extensions."
and more.
Note that historically some hardware could be damaged by bad settings so
vendor data for both the card and display itself can be important.
