how to change monitor freq in FC4?

   While installing Fedora Core 4 on a Dell Dimension 4700 with Dell
E173FP LCD display, I noticed that the refresh rate selected (76 Hz) 
for displaying 1280x1024 shifted the default display on the LCD to the
left by about 1/2 inch. The optimal (the default) setting for the
E173FP is 60 Hz for 1280x1024. However, I can't access the desired
60 Hz refresh rate using the Desktop->Preferences->Screen Resolution
menu item. The Screen Resolution Preferences dialog that appears only
shows 76 Hz in the dropdown menu. I would like to do this through the
gui if possible rather than resorting to manually calculating
modelines (yuck). Thanks in advance for any advice.
