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 color is unstable or mono-colored. • Check the connection status of the LVDS cable.
• Check whether the LVDS cable is connected correctly following the
LVDS Pin Map Guide.
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.
