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

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
