  horizontal scan rate
  
     <hardware> (HSR) The measure of how many scan lines of
     pixels a monitor can display in one second, expressed in
     kHz (generally somewhere between 20 and 100 kHz).
  
     The HSR is controlled by the horizontal sync signal generated
     by the video controller, but is limited by the speed with
     which the monitor can scan the electron beam horizontally
     across the screen and then return it to the beginning of the
     next line.
