Possible cause and remedy
• Adjust <Brightness> or <Contrast> from the <Color>
menu.
(The LCD monitor backlight has a fixed life span. When
the screen becomes dark or begins to flicker, contact
your local dealer.)
• Use a screen saver or off timer function for a long-time
image display.
• Afterimages are particular to LCD monitors. Avoid
displaying the same image for a long time.
• This is due to LCD panel characteristics and is not a
failure.
• Leave the monitor with a white screen. The symptom
may disappear.
• When utilizing [ContrastEnhancer] and/or
[OutlineEnhancer] function, the normal images may not
be displayed since the display gradation abnormality or
noise may occur on the screen depending on the display
pattern.
• When [OutlineEnhancer] is set excessively, the
characters on the screen may be affected by color.

headphone jack.
