n About the GP's Display Panel
• The GP's currently displayed data, its voltage
*1
and brightness setting 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.
• Shadows may appear at the top of the LCD. 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.
