per second is called vertical frequency, or refresh rate, and is represented by Hz.

• Horizontal Frequency: The time it takes to display one horizontal line is called the horizontal cycle. If 1 is divided by the horizontal interval, the result is the number of horizontal

lines displayed per second. This is called horizontal frequency and is represented by kHz.

• Check if the graphics card’s resolution or frequency is within the range allowed by the monitor and set it to the recommended (optimal) resolution Control Panel > Display >

• The setting methods may be different depending on the computer or operating system, and some resolutions may not be available depending on the performance of the

graphics card. If this is the case, contact the manufacturer of the computer or graphics card for assistance.
