6. Horizontal bars of distortion
appear.
Decrease the horizontal bars using the
<Phase>. (p. 29)
7. Letters and lines appear blurred. Adjust the blurred lines using <Smoothing>
(p. 31)
8. Distortion appears like the figure
below.
This happens when both composite (X-OR)
input signal and separate vertical
synchronizing signal are input. Please select
one of the two.
9. 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.)
10. Afterimages appear. Do you use the screen saver or timer when
displaying the same image for extended
periods of time?
Afterimages are particular to LCD monitors.
Avoid displaying the same image for extended
periods of time.
11. 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.
12. Fingerprints remain on the screen. Leaving the screen white or black may solve the
problem.
13. The noise appears on the
screen.
Change the mode in <Signal Filter> in the
<Screen> menu.
14. The <Smoothing> cannot be
selected.
<Smoothing> is disabled when the screen is
displayed in the 1280 x1024.
The image size is doubled both in horizontally
and vertically to (i.e. 1280 x 960 enlarged from
640 x 480) provide clear focus which does not
require this function.
15. The Main menu of
ScreenManager does not
operate.
The adjustment lock is probably on. To unlock:
turn the LCD monitor off. Then, while pressing
the Auto Adjustment Button, turn the power on.
