Introduction

Congratulations on your purchase of a Sony Multiscan

series monitor.

This monitor incorporates over 25 years of Sony experience

with Trinitron® display technology, ensuring excellent

performance and outstanding reliability.

The advanced design of this monitor together with Digital

Multiscan Technology allows it to sync to any video mode

within its wide scan range.

In addition, its four factory preset color modes and user

adjustable color modes give you unprecedented flexibility

in matching on-screen colors to hard copy printouts.

Furthermore, this monitor features digital control with OSD

(On Screen Display). It delivers easier adjustment by

visualizing your control statement. All together, it delivers

incredible performance with the quality and support you

can expect from Sony.

Trinitron® is a trademark of Sony Corporation.

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.

Transportation

When you transport this monitor for repairing or shipping,

use the original carton box and packing materials.

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.

User modes

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.

2) Windows is a registered trademark of Microsoft Corporation in

the United States and other countries.

Selecting the Input Signal

This monitor has two signal input connectors and can

connect two computers. When the power of both computers

is on, select the signal you want to input as follows.

1Turn on power of the monitor and the computer.

2Select the input signal.

To input the signal from the computer connected to

the 5 BNC’s connector

Set the INPUT switch to BNC.

To input the signal from the computer connected to

the HD15 connector

Set the INPUT switch to HD15.

If only one computer is connected or turned on

Set the INPUT switch to AUTO (center position). The

input signal is automatically selected.

3If necessary, adjust the user controls according to

your preference on pages 9 to 15.

When you set the INPUT switch to “AUTO”and

connect computers to both connectors

If you turn on or restart the computer you want to input a signal

from, or the computer is in power saving mode, the monitor may

automatically select another computer’s signal. This is because no

signal is input to the monitor at that moment. If this happens,

select the signal using the INPUT switch.

For the customers using the Windows95

Even if you select SONY for the maker on the device select screen,

the model name (GDM-W900) may not appear. In this case, select

the DDC standard monitor.

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.

DDC is a trademark of Video Electronics Standard Association.

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.

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.

Power saving operation

•The H-sync is not present.

/ The unit goes into standby state.

•The V-sync is not present.

/ The unit goes into suspend state.

•Both the H-sync and V-sync are not present.

/ The unit goes into active-off state.

The monitor requires a video card or screen saver software

which switches off one or both sync signals to activate the

power saving function.

Caution

If no video signal is input to the monitor, or if the INPUT

switch is set to the connector to which no signal is input

when you turn on the monitor, the input signal warning

indicator (page 18) appears. After 30 seconds, the Power

Saving function automatically puts the monitor into the

Active-off state and the POWER SAVING indicator lights

up. Once the horizontal and vertical syncs are sensed, the

monitor will automatically return to its Normal operation

state.

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.

White does not look white

• Check that the power cord is properly connected.

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

• 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.

• Check that the video frequency range is within that specified for the monitor.

(Horizontal: 30 – 96 kHz, Vertical: 50 – 160 Hz)

• 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.

• 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 the Macintosh adapter and the video signal cable are properly connected,

and the dip switches of the adapter are properly set.

• When you cannot find “GDM-W900” among the Sony monitors on the Windows95

device select screen, select the DDC standard monitor.

• 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.

• 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).

• 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.

• 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).

• 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.

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

• Adjust the convergence (pages 11, 14).

• 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).

• 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.

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

computer’s manual.

• 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.

• 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.

• 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.

• When the power is turned on, the auto-degauss cycle is activated. While the Auto-

degauss cycle is activated, a hum may be heard. This is not a malfunction.

• Lightly pat the sides of the monitor.
