NOTE
• Vertical Frequency: In order to display an image, the screen must be refreshed dozens of times per second, like a fluorescent lamp. The number of times the screen is refreshed 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 > 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 3440 x 1440 resolution. If the resolution cannot be displayed, contact the manufacturer of your graphics card.
• Displaying a still image for a prolonged time may cause damage to the screen, resulting in the retention of the image.
• To extend the lifetime of the monitor, use a screensaver.
