Open this file /etc/X11/xorg.conf .

Check for monitor section. A sample data will be like this

Code:

Section "Monitor"
         Identifier   "Monitor0"
         VendorName   "Philips"
         ModelName    "107E"
         DisplaySize  360        270
         HorizSync    30.0 - 70.0
         VertRefresh  85         
         Option      "dpms"
EndSection

You can modify your monitor refresh rate in the above section
