the frequency range by referring to the

NOTE:
Vertical Frequency - to enable
the user to watch the monitor display,
screen image should be changed tens
of times every second like a fluorescent
lamp. The vertical frequency or refresh
rate is the times of image display per
second. The unit is measured in Hz.
Horizontal Frequency - the horizontal
interval is the time to display one
vertical line. When 1 is divided by the
horizontal interval, the number of
horizontal lines displayed every second
can be tabulated as the horizontal
frequency. The unit is measured in kHz.
