• Vertical frequency: To enable the user to watch the set, the screen image should be
changed tens of times every second like a fluorescent lamp. The vertical frequency or
refresh rate is the times per second the image changes. The unit is 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 kHz.
