Imaging Problems
Image vibrates on the screen
• Check that the signal cable is properly
securely connected to the graphics
board or PC.
Image appears blurred, indistinct or too
dark
• Adjust the contrast and brightness on
On-Screen Display.
An "after-image", "burn-in" or "ghost
image" remains after the power has been
turned o.
• Uninterrupted display of still or static
images over an extended period may
cause "burn-in", also known as "after-
imaging" or "ghost imaging", on your
screen. "Burn-in", "after-imaging",
or "ghost imaging" is a well-
known phenomenon in LCD panel
technology. In most cases, the "burn-
in" or "after-imaging" or "ghost
imaging" will disappear gradually
over a period of time after the power
has been switched off.
• Always activate a moving screen
saver program when you leave your
monitor unattended.
• Always activate a periodic screen
refresh application if your LCD
monitor will display unchanging
static content.
• Failure to activate a screen saver, or
a periodic screen refresh application
may result in severe “burn-in” or
“after-imaging” or “ghost imaging”
symptoms that will not disappear
