ENGLISH
After-image appears on the product.
Problem Action
After-image appears when the product is
turned off.
•If you use a fixed image for a long time, the pixels may be damaged.
Use the screen-saver function.
•When a dark image is displayed on the screen after an image with high
contrast (black and white or gray), this may cause image sticking. This
is normal for LCD screen products.
Screen color is abnormal.
Problem Action
Screen has poor color resolution (16
colors).
•Set the number of colors to more than 24 bits (true color). Select
[Control Panel] → [Display] → [Settings] → [Color Table] in Windows.
(The settings may differ depending on your operating system.)
Screen color is unstable or mono-colored. •Check the connection status of the signal cable. Or, re-insert the PC
graphics card.
Do black spots appear on the screen? •Several pixels (red, green, blue, white, or black color) may appear on the
screen, which can be attributable to the unique characteristics of the
LCD panel. This is not a malfunction of the LCD.

CAUTION
•Image sticking does not occur when using constantly changing images but may occur when using a fixed image for an
extended period of time. Therefore, it is recommended that you use the instructions below to decrease the likelihood
of image sticking occurring when using a fixed image. It is recommended that you change the screen at least once
every 12 hours at the very minimum; if done more frequently, the prevention of image sticking is more effective.
Recommended operating conditions
1 Change the background and the character colors using the same time interval.
When changing colors, using complementary colors helps to prevent image sticking.

2 Change the image using the same time interval.
Make sure that the characters or images before changing the image remain in the same location after changing the
image.
What is image sticking?
When the LCD panel displays a static image for an extended period of time, it can cause a voltage difference between
the electrodes that operate the liquid crystals. When the voltage difference between the electrodes builds up over
time, liquid crystals have a tendency to remain aligned in one direction. During this process, a previously displayed image
remains visible. This phenomenon is referred to as image sticking.

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. 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.
