If the screen is difficult to read
TEST THE VIDEO EXTENSION CABLE (IF USED)—If you are using a
video extension cable and removing the cable solves the problem, the cable is
defective.
TEST ANOTHER MONITOR If another monitor is available, connect it to
the computer.
CHECK THE DIAGNOSTIC LIGHTS See page 60.
CHECK THE MONITOR SETTINGS See the monitor documentation for
instructions on adjusting the contrast and brightness, demagnetizing
(degaussing) the monitor, and running the monitor self-test.
MOVE THE SUBWOOFER AWAY FROM THE MONITOR If your speaker
system includes a subwoofer, ensure that the subwoofer is at least 60 cm (2 ft)
away from the monitor.
MOVE THE MONITOR AWAY FROM EXTERNAL POWER SOURCES
Fans, fluorescent lights, halogen lamps, and other electrical devices can cause the
screen image to appear "shaky." Turn off nearby devices to check for interference.
ROTATE THE MONITOR TO FACE A DIFFERENT DIRECTION Eliminate
sunlight glare, which can cause poor picture quality.
