Preface
About the GP's Display Panel
• The GP's currently displayed data, its voltage
*1
and brightness set-
ting each affect the intensity of Contouring . (i.e, when some parts of
the screen are brighter than others, creating a wavelike pattern)
• There are minute grid-points (dark and light) on the Display Panel's
surface. This is part of the GP's design and not a defect.
• Extended shadows, or "Crosstalk" may appear on the sides of screen
images. This is normal for an LCD display.
• Sometimes the display area may look as if the display colors have
changed. This is a common attribute of LCD's and is not a defect.
• Displaying a single image for long periods can cause an afterimage
to remain when the display is changed to another screen.
To prevent this effect:
Use the GP's "Stand-by Mode", which automatically turns the
screen OFF when there is no input for a specified period of
time.
