NOTE
y 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.
y Horizontal Frequency: The time it takes to display one horizontal line is called the horizontal cycle. 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.
NOTE
y Check if the video card's resolution or frequency is within the range allowed by the Product and set to
the recommended (optimal) resolution in Control Panel > Display > Settings.
y Failing to set 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.
y The configuration procedure may differ depending on your computer and/or operating system. Also,
some video cards may not support certain resolutions. If this is the case, contact the manufacturer of
the computer or video card for assistance.
y Some video cards may not support the 2560x1080 resolution.
If the resolution cannot be displayed, contact the manufacturer of your video card.
