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

ROTATE THE MONITOR TO FACE A DIFFERENT DIRECTION — Eliminate 
sunlight glare, which can cause poor picture quality.
