Points to check with Possible Solutions
Adjust the image position using the <Position>
(p. 24).
The two display modes, VGA 720 × 400
(70 Hz) and 320 × 200 (70 Hz), have the same
signal timings. Using this adjustment selects
the appropriate display mode. (This function
effects only when the resolution is VGA
720 × 400 (70 Hz) or 320 × 200 (70 Hz).
If the problem persists, use the graphics
board's utility software to change the display
position if available.
Decrease the vertical bars using the
<Clock> (p. 23).
Decrease the horizontal bars using the
<Phase> (p. 24).
Switch the <Smoothing> (p. 25) mode to "Off".
Adjust the <Brightness> (The backlight of the
LCD monitor has a fixed life span. When the
screen becomes dark or begins to flicker,
please consult your dealer.)
Do you use the screen saver or timer (p. 20)
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.
<Smoothing> is disabled when the screen is
displayed in the 1280 × 1024.
