3. Display position is incorrect. Adjust the image position using the <Position>
(p. 23).
The two display modes, VGA 720 x 400 (70 Hz)
and 320 x 200 (70 Hz), have the same signal
timings. Using <VGA Selection> selects the
appropriate display mode. (This function effects
only when the resolution is VGA 720 x 400 (70
Hz) or 320 x 200 (70 Hz).
If the problem persists, use the graphics
board’s utility software to change the display
position if available.

appear.
Decrease the horizontal bars using the
<Phase> (p. 23).

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.
9. 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.
10. Fingerprints remain on the
screen.
Leaving the screen white may solve the
problem.

selected.
<Smoothing> is disabled when the screen is
