Horizontal Frequency
The time to scan one line connecting the right edge to the left edge of the 
screen horizontally is called Horizontal Cycle and the inverse number of the 
Horizontal Cycle is called Horizontal Frequency. Unit: kHz  
 
Vertical Frequency
Like a fluorescent lamp, the screen has to repeat the same image many 
times per second to display an image to the user. The frequency of this 
  
repetition is called Vertical Frequency or Refresh Rate. Unit: Hz
