· 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 > Settings in Windows. (The settings may differ depending on the operating system (OS) you use.)
· Not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a dimmed screen, a truncated display area or misalignment of the 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. · Some graphics cards may not support 2560 x 1440 resolution. If the resolution cannot be displayed, contact the manufacturer of your graphics card.
