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
