Problems Possible cause and remedy
1. The screen is too bright or too dark. • Adjust <Brightness> or <Contrast> from the <Color>
menu.
(The LCD monitor backlight has a xed life span. When
the screen becomes dark or begins to icker, contact
your local dealer.)

image display.
• Afterimages are particular to LCD monitors. Avoid
displaying the same image for a long time.
3. Green/red/blue/white dots or defective dots remain
on the screen.
• This is due to LCD panel characteristics and is not a
failure.

• Leave the monitor with a white screen. The symptom
may disappear.
5. Noise appears on the screen. • When utilizing [ContrastEnhancer] and/or
[OutlineEnhancer] function, the normal images may not
be displayed since the display gradation abnormality or

characters on the screen may be affected by color.
