– Horizontal Frequency
The time required to scan a single line
from the left to the right side of the
screen is called a horizontal cycle.
The reciprocal number of a horizontal
cycle is called horizontal frequency.
Horizontal frequency is measured in
kHz.
– Vertical Frequency
The product displays a single image
multiple times per second (like a
fluorescent light) to display what
the viewer sees. The rate of a single
image being displayed repeatedly per
second is called vertical frequency
or refresh rate. Vertical frequency is
measured in Hz.
