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 in
Windows set it to the recommended (optimal) resolution in Control Panel > Display > Settings. (May differ
depending on your operating system (OS).)
•
Not setting the video 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.
•
Normal graphics cards do not support 3840 x 2160 resolution. If the resolution cannot be displayed, contact
the manufacturer of your graphics card.
