Troubleshooting Tip
No Picture
Image Persistence
Image persistence occurs when a ghost of an image remains
on the screen after the monitor has been turned off. Unlike a
CRT monitor, an LCD monitor’s image persistence is not
permanent. To erase an image ghost, turn the monitor off for
as long as the image was displayed. If the image was on for
one hour and the ghost of the image remains, the display
should be turned off for one hour to erase the image. To
avoid this problem, use a screen saver.
