The Auto-degauss function demagnetizes the metal frame of the CRT in order to obtain a
neutral field for uniform color reproduction. If a second degauss cycle is needed, allow a
minimum interval of 20 minutes for the best result.

If the problem persists, call your authorized dealer from a location near your monitor.
•
Note the model name and the serial number of your monitor. Also note the make and name of your computer and video
board.
•
Check that the video sync signal is specified for the monitor.
•
Check your graphics board manual for the proper monitor setting on your monitor.
•
Check this manual and confirm that the graphics mode and the frequency at which you
are trying to operate is supported. Even within the proper range, some video boards
may have a sync pulse that is too narrow for the monitor to sync correctly.

•
Adjust centering or size (pages 4, 5).
•
Some video modes do not fill the screen to the edge of the monitor. There is no single
answer to solve the problem. There is tendency to have this problem on higher refresh
timings.
•
Adjust the Contrast and Brightness controls (page 4). Several brands of SVGA boards
have an excessive video output level which creates a fuzzy picture at max contrast.

•
Move electrical (magnetic) devices that may be creating electrical interference away
from the monitor.
•
If you have another monitor close to this monitor, increase the distance between them to
reduce the interference.
•
Your office may have electric power wiring behind the wall. Move the monitor away
from the wall.
•
This wire stabilizes the vertically striped Aperture Grille. This Aperture Grille allows
more light to pass through to the screen giving the Trinitron
** CRT more color and
brightness.

Then, adjust the Rotation (page 5).
•
Adjust the Pincushion (page 5).
•
Due to the relationship between resolution, monitor dot pitch, and the pitch of some
image patterns, certain screen backgrounds, especially gray, sometimes show moire.
This can only be eliminated by changing your desktop pattern.
