- Troubleshooting Your LifeBook
The display has bright or
dark spots.
If the spots are very tiny and
few in number, this is normal
for a large LCD display.
This is normal; do nothing.
If the spots are numerous or
large enough to interfere with
your operation needs.
Display is faulty; contact your support representative.
The application display
uses only a portion of
your screen and is sur-
rounded by a dark frame.
You are running an applica-
tion that does not support
the system’s native resolution
and display compression is
enabled.
Display compression gives a clearer but smaller display for
applications that do not support the system’s native pixel
resolution. You can fill the screen but have less resolution by
changing display compression settings. These settings can
be changed in the Intel GMA control panel.

external monitor and it
does not display any infor-
