(e.g. slightly light or dark).
12. Fingerprints remain on the screen.
13. The noise appears on the
screen.
14. The <Smoothing> cannot be
selected.
15. The Main menu of
ScreenManager does not
operate.
Points to check with Possible Solutions
Decrease the horizontal bars using the
<Phase>. (p. 29)
Adjust the blurred lines using <Smoothing>
(p. 31)
This happens when both composite (X-OR)
input signal and separate vertical
synchronizing signal are input. Please select
one of the two.
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.)
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.
This is due to the characteristics of the panel
itself and not the LCD product.
Leaving the screen white may solve the problem.
Change the mode in <Signal Filter> in the
<Screen> menu.
<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.
The adjustment lock is probably on. To unlock:
turn the LCD monitor off. Then, while pressing
the Auto Adjustment Button, turn the power on.
