     <hardware> (Or "vertical refresh rate", "vertical scan rate")
     The maximum number of frames that can be displayed on a
     monitor in a second, expressed in Hertz.
  
     The scan rate is controlled by the vertical sync signal
     generated by the video controller, ordering the monitor to
     position the electron gun at the upper left corner of the
     raster, ready to paint another frame.  It is limited by the
     monitor's maximum horizontal scan rate and the resolution,
     since higher resolution means more scan lines.  Increasing
     the refresh rate decreases flickering, reducing eye strain,
     but few people notice any change above 60-72 Hz.
