Horizontal Frequency
The time to scan one line connecting the
right edge to the left edge of the screen
horizontally is called the Horizontal Cycle
and the inverse number of the Horizontal
Cycle is called the 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
the Vertical Frequency or Refresh Rate.
Unit: Hz
