and is represented by Hz.
Horizontal Frequency: The time it takes to display one horizontal line is called the horizontal cycle.
yy
The number of horizontal lines displayed in one second can be calculated by dividing one by the horizontal cycle. This is called horizontal frequency and is represented by kHz.

Check if the video card's resolution or frequency is within the range allowed by the monitor and set to
yy
the recommended (optimal) resolution in Control Panel > Display > Settings.
Failing to set the video card to the recommended (optimal) resolution may result in blurred text, a
yy
dimmed screen, a truncated display area or misalignment of the display.
The configuration procedure may differ depending on your computer and/or operating system. Also,
yy
some video cards may not support certain resolutions. If this is the case, contact the manufacturer of
the computer or video card for assistance.
Some video cards may not support the 2560x1080 resolution. yy
If the resolution cannot be displayed, contact the manufacturer of your video card.
The display color is abnormal.
Does the display appear discolored
(16 color)?
Does the display color appear unstable or in monochrome?
Are there spots on the screen?
yySet the color to 24 bit (true color) or higher. In Windows, go to Control
Panel > Display > Settings > Color Quality.

yy
Adjust the stand angle to obtain the best view of the screen.
You should be looking
slightly down at the screen.
Adjust the angle
So that there is no reflection
or glare from the screen.
Place your hands gently on
the keyboard, keeping your
arms bent at the elbows and
extended horizontally in front
of you.
