On any modern monitor you should be able to tell X absolutely nothing
about frequencies. The DCC info for the monitor that the driver picks
up should be correct and simply work. If it didn't the monitor would
not work with windows XP and newer.
So really don't worry about it, just tell X the resolution you want (or
possibly don't do that either and it normally should default to the
native resolution of the screen). These days the less you tell X, the
more likely it is to just work.
