Hinweise
• Aus ergonomischen Gründen wird empfohlen, die
Grundfarbe Blau nicht auf dunklem Untergrund zu
verwenden (schlechte Erkennbarkeit, Augenbelastung bei zu
geringem Zeichenkontrast).
• Aus ergonomischen Gründen sollten nur Darstellungen auf
dunklem Hintergrund bei Vertikalfrequenzen ab
60 Hz (ohne Zeilensprung) benutzt werden.
• Die Konvergenz des Bildes kann sich auf Grund des
Magnetfeldes am Ort der Aufstellung aus der korrekten
Grundeinstellung verändern. Zur Korrektur empfiehlt es sich
deshalb, die Regler an der Frontseite für H STAT und V STAT
so einzustellen, daß die getrennt sichtbaren Farblinien für
Rot, Grün und Blau bei z.B. der Darstellung eines
Buchstabens zur Deckung (Konvergenz) gelangen.
Siehe hierzu auch die Erklärungen zu H STAT und V STAT.

Precautions
Installation
• Prevent internal heat build-up by allowing adequate air
circulation. Do not place the unit on surfaces (rugs,
blankets, etc.) or near materials (curtains, draperies) that
may block the ventilation holes.
• Do not install the unit near heat sources such as radiators
or air ducts, or in a place subject to direct sunlight,
excessive dust, mechanical vibration or shock.
• Do not place the unit near equipment which generates
magnetism, such as a converter or high voltage power
lines.

Maintenance
• Clean the cabinet, panel and controls with a soft cloth
lightly moistened with a mild detergent solution. Do not
use any type of abrasive pad, scouring powder or solvent,
such as alcohol or benzine.
• Do not rub, touch, or tap the surface of the screen with
sharp or abrasive items, like a ballpoint pen or a
screwdriver. This type of contact may result in a scratched
picture tube.

Warning on power
connection

• Use the supplied power cord.
For the customers in UK
If you use the monitor in UK, please use the UK cable with
UK plug (not supplied).
• Before disconnecting the power cord, wait for at least 30
seconds after turning off the power to allow the static
electricity on the CRT display surface to discharge.
• After the power has been turned on, the CRT is
demagnetized for approximately five seconds. This
generates a strong magnetic field around the bezel, which
may affect the data stored on magnetic tapes or disks near
the bezel. Place such magnetic recording equipment and
tapes/disks away from this unit.
The socket-outlet should be installed near the
equipment and be easily accessible.

Transportation
When you transport this monitor for repairing or shipping,
use the original carton box and packing materials.

When using a video mode that is not one of the preset
modes, some fine tuning may be required to optimize the
display to your preference. Simply adjust the monitor
according to the adjustments instructions on pages 9 to 15.
The adjustments will be stored automatically and recalled
whenever that mode is used.
A total of 16 user-defined modes can be stored in memory.
If a 17th mode is entered, it will replace the first.
For less common modes, and modes that may evolve in the
future, the Digital Multiscan Technology of this monitor will
perform all of the complex adjustments necessary to ensure
a high quality picture for any timing in its frequency range.
However, due to the wide variety of video boards on the
market, it may be necessary for the user to fine tune the
vertical/horizontal size and centering.
Recommended horizontal timing conditions
Horizontal sync width should be more than 0.8 µsec.
Horizontal blanking width should be more than 2.7 µsec.
Note for Windows® 2) users
Check your video board manual or the utility program
which comes with your graphic board and select the highest
available refresh rate to maximize monitor performance.

Plug & Play
This monitor complies with the DDC1, DDC2B and
DDC2AB which are the Display Data Channel (DDC)
standards of VESA.
When a DDC1 host system is connected, the monitor
synchronizes with the V. CLK in accordance with the VESA
standards and outputs the EDID (Extended Display
Identification Data) to the data line.
When a DDC2B or DDC2AB host system is connected, the
monitor automatically switches to each communication.

Power Saving
Function
This monitor is capable of three states of reduced power
consumption. By sensing the absence of video signals and
one or both sync signals coming from the host computer, it
will reduce power consumption as follows.

Damper Wire
Using a white background, very thin horizontal lines on the
screen are visible as shown below. These lines are damper
wires.
The Trinitron tube has a vertically striped Aperture Grill
inside. The Aperture Grille allows more light to pass
through to the screen giving the Trinitron CRT more color
and brightness.
These damper wires are attached to the Aperture Grille to
prevent vibration of the Aperture Grille wire so that the
screen image is constantly stable.

Troubleshooting
This section may help you isolate a problem and as a result, eliminate the need to contact technical support, allowing
continued productivity.
Note the model name and the serial number of your monitor. Also note the make and name of your computer and video
board.

Symptom

Check these items

No picture
If neither u (power)
indicator nor POWER
SAVING indicator is lit

• Check that the power cord is properly connected.
• Check that the u (power) switch is in the “on” position.

If the POWER SAVING
indicator is lit

•
•
•
•

If the u (power) indicator
is flashing in green

• Check that the video frequency range is within that specified for the monitor.
(Horizontal: 30 – 96 kHz, Vertical: 50 – 160 Hz)

If the u (power) and/or
POWER SAVING
indicators are flashing in
orange

• Turn the monitor off and on. If the indicator is off, the monitor is in the normal
condition. If the indicator is still flashing, there is a potential monitor failure.

If you do the above
procedures and the
monitor does not recover

• Unplug the video input 1 and 2 connectors and wait for 5 seconds. Then press and hold
the > + button for 2 seconds to display the color bars. If the color bars appear, the
monitor may be in normal condition. Turn the monitor off and on to return to the
normal operation mode. If the color bars do not appear, there is a potential monitor
failure.

Check that your computer power switch is in the “on” position.
The monitor will recover when you press any key on the keyboard of the computer.
The INPUT switch setting is incorrect.
Check that the video signal cable is properly connected and all plugs are firmly seated in
their socket.
• Check that the 5 BNC’s are connected in the correct order (from the power cord side:
Red–Green–Blue–HD–VD).
• Ensure that no pins are bent or pushed in the HD15 video input connector.
• Check that the video board is seated completely in the proper bus slot.

EN
F

If using a Macintosh
system

• Check that the Macintosh adapter and the video signal cable are properly connected,
and the dip switches of the adapter are properly set.

If using a Windows95

• When you cannot find “GDM-W900” among the Sony monitors on the Windows95
device select screen, select the DDC standard monitor.

ES
I
J

Picture is scrambled

• Check your graphic board manual for proper monitor setting.
• Check this manual and confirm that the graphic mode and the frequency at which you
are trying to operate is supported (page 5). Even within the proper range some video
boards may have a sync pulse that is too narrow for the monitor to sync correctly.

Color is not uniform

• Degauss the monitor (page 16).
If you place equipment which generates a magnetic field such as a loudspeaker, or you
change the direction of the monitor, color may lose uniformity.
This function is to demagnetize the metal frame of the CRT 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.
• Adjust the landing (page 11).

You cannot adjust the
monitor with the buttons on
the front panel

• If the control lock function is set to on, set it to off on the OPTION OSD (page 16).
You will be able to adjust the monitor.

White does not look white

• Adjust color (page 12, 15).
• Check that the 5 BNC’s are connected in the correct order (from the power cord side:
Red–Green–Blue–HD–VD).

Troubleshooting
Symptom

Check these items

Screen image is not centered
or sized properly

• Adjust the centering or size (pages 10, 14).
• Some video modes do not fill the screen to the edge of the monitor. There is no single
answer to solve the problem. This problem tends to occur on higher refresh timings.

Edges of the image are
curved

• Adjust the geometry items such as pincushion and keystone distortion (page 11, 14).

White lines show red or blue
shades at edges

• Adjust the convergence (pages 11, 14).

Picture is fuzzy

• Adjust the contrast and brightness (page 9).
• Degauss the monitor (page 16).
If you place equipment which generates a magnetic field such as a loudspeaker, or you
change the direction of the monitor, color may lose uniformity.
This function is to demagnetize the metal frame of the CRT 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 red or blue shades are found at the edge of images, adjust the convergence (pages 11,
14).
• If the moire is cancelled, the picture may become fuzzy. Adjust so that the picture is as
clear as possible (page 11, 15).

Picture bounces or has wavy
oscillations

• Isolate and eliminate any potential sources of electric or magnetic fields. Common causes
for this symptom are electric fans, fluorescent lighting, laser printers, and so on.
• If you have another monitor close to this monitor, increase the distance between them to
reduce the interference.
• Try plugging the monitor into a different AC outlet, preferably on a different circuit.
• Try the monitor on a completely different computer in a different room.

Picture is not stable

• Set the refresh rate to non-interlace of 75 Hz or more on the computer referring to the
computer’s manual.

Picture appears to be
ghosting

• Eliminate the use of video cable extension cable and/or video switch boxes if this
symptom occurs. Excessive cable length or weak connection can produce this symptom.

Two fine horizontal lines
(wires) are visible

• These wires stabilize the vertically striped Aperture Grille (page 17). This Aperture Grille
allows more light to pass through to the screen giving the Trinitron CRT more color and
brightness.

Wavy or elliptical (moire)
pattern is visible

• Cancel the moire (page 11, 15).
The moire may be modified depending on the connected computer.
• Due to the relationship between resolution, monitor dot pitch and the pitch of some
image patterns, certain screen backgrounds, especially gray, sometimes show moire.
Change your desktop pattern.

Hum is heard right after the
power is turned on

• When the power is turned on, the auto-degauss cycle is activated. While the Autodegauss cycle is activated, a hum may be heard. This is not a malfunction.

Because of vibration and
shock during transportation,
the Aperture Grille may
occasionally slip out of place
and black stripes may
appear

• Lightly pat the sides of the monitor.
