Well I believe here we have a mixup in terms. Whenever I have looked at
the book that comes with a monitor it tells me what refresh rate the
monitor will use for each resolution it will accept.

Now it is true that you can set the refresh range rate the video card
will use in xorg.conf but you will still have the refresh rate the
monitor is set up to use. If the video card uses a refresh rate that the
monitor won't handle (in the old days you could damage the monitor) the
monitor will just not display the image. So in xorg.cong you are
supposed to choose a refresh range that is indicated in the monitor
manual.
