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
