Problems Points to check with possible solutions
10. The screen is too bright or too
dark.
Adjust the <Brightness> (The backlight of the LCD
monitor has a fixed life span. When the screen
becomes dark or begins to flicker, please contact
your dealer.)
Some input signal timing causes greenish screen.
Change the Sync Switch setting. (p.25).
11. Afterimages appear.
When the screen image is changed after displaying
the same image for a long period, an afterimage
may appear. The “Afterimage” can be removed
gradually by changing the displayed image. Use the
“Off Timer” function and avoid keeping the screen
on all the time. (p.24)
12. The screen has defective pixels
(e.g. slightly light or dark).
This is due to the characteristics of the panel itself
and not the LCD product.

screen.
Leaving the screen white may solve the problem.
