Pat,
	That's not the actual refresh range for the monitor, it's just the  
currently used range.
	What you want to do is search for "{maker} {model} horizontal  
refresh" in google; the pages which come up are the ones you want to  
refer to for your xorg.conf configuration.
	Also, just as a sidenote, setting the refresh rate of the monitor to  
the highest possible range will help your eyes as they are accustomed  
to a higher refresh rate than 60 Hz
