large enough to interfere with
your operation needs.

doesn't support the system's
native resolution and display
compression is enabled.
Power Management default is
set on low to conserve power.
Your external monitor is not
properly installed.

setup with the correct software
driver for that device.

compatible with your LIFEBOOK

its own set of error message dis-
plays.
Possible Solutions
This is normal; do nothing.
Display is faulty; contact your support representative.
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.
