Ehm, ask DDC maybe?  Of course if you use the DVI connector then it
isn't even relevant (and believe me you want to use the DVI connector).
Since all screens the last decade have DDC there is little need to
provide such specs to the user, since the system will auto detect it and
do the right thing.

Now in my experience most LCD screens have a vertical refresh support of
50 to 75hz, with 60 being prefered whenever possible.

As some examples:

Eizo has a 24" 1920x1200 widescreen and is uses:
DVI: Vertical 59-61Hz, Horizontal 31-76KHz
VGA: Vertical 49-86Hz, Horizontal 24-94KHz

I can't check what my Dell 2407WFP-HC does, since it is currently
connected by DVI in which case it doesn't even bother mentioning
anything it just does the resolution using a single link DVI signal.

You can usually find the specs simply by connecting the monitor and
starting X, then look at the /var/log/Xorg.0.log file and find where it
lists the monitor information.
