• 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.

Introduction
Congratulations on your purchase of a Sony Multiscan SE
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 the SE series together with Digital
Multiscan Technology allows it to sync to any video mode
within its wide scan range. In addition, its three factory
preset color modes and three user adjustable color modes
give you unprecedented flexibility in matching on-screen
colors to hard copy print outs. Furthermore, this monitor
features digital controls 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.
The GDM-17SE2T is the model used for illustration
purposes.
• Before disconnecting the power cord, wait for at least 30
seconds after turning off the power switch to allow for
the discharging of static electricity on the CRT display
surface.
• After the power has been turned on, the CRT is
demagnetized for approximately 5 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 apart from this unit.
The socket-outlet should be installed near the equipment
and be easily accessible.
Installation
• Prevent internal heat build-up by allowing adequate air
circulation. Do not place the unit on surfaces (rugs,
blankets, etc.) nor near materials (curtains, draperies)
that may block the ventilation holes.
• Do not install the unit near heat sources such as
radiators or air ducts, nor 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, alkaline cleaner, 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 ball point pen or a screw
driver. Otherwise, this type of contact may result in a
scratched picture tube.
Precautions
• Use a proper power cord for your local power supply.
For the customers in U.S.A.
If you do not do this, this monitor will not conform to
mandatory FCC standards.
For the customers in UK
If you use the monitor in UK, please use the supplied
UK cable with UK plug.
Examples of plug shape:
for 100 to 120 V AC for 220 V to 240 V AC for 240 V AC only

Preset and User Modes
Using your Monitor
The Multiscan 17seII/20seII has factory preset modes for the
10 most popular industry standards for true “plug and
play” capability.
When using a video mode that is not one of the 10 factory
preset modes, some fine tuning may be required to optimize
the display to your preferences. Simply adjust the monitor
according to the preceding adjustment instructions. The
adjustments will be stored automatically and recalled
whenever that mode is used.
A total of 15 user-defined modes can be stored in memory.
If the 16th mode is entered, it will replace the first.
For less common modes, and modes that evolve in the
future, the Digital Multiscan Technology of the Multiscan
17seII/20seII 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 duty should be: >4.8% of total
horizontal time.
Horizontal blanking width should be: >3.0 µsec.
Note: For Windows4)
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.

Troubleshooting
This section may help you isolate a problem and as a result,
eliminate the need to contact technical support, allowing
continued productivity.
No picture
/ If neither the u (power) indicator nor the
POWER SAVING indicator is not lit.
— Check that the power cord is properly
connected.
— Check that the power switch is in the “on”
position.
/ If the POWER SAVING indicator is lit.
— 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.
— Check that the video cable is properly
connected and all plugs are firmly seated in
their socket.
— Check that the 5 BNC's are connected in the
right order (from power cord side: Red-
Green-Blue-HD-VD).
— Ensure that no pins are bent or pushed in
the HD15 connector of the cable.
— Check that the video card is seated
completely in a proper bus slot.
— Check that the video frequency range is
within that specified for the monitor.
— If using a Macintosh system, check that the
Macintosh adapter and the video signal
cable are properly connected.
/ If the u (power) and/or the POWER SAVING
indicators are both flashing.
— 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 cable (HD15/5 BNC's)
then press and hold the > + button for 2
seconds to display the color bars. Then,
turn the monitor off and on by pressing the
u power switch.
If the monitor does not recover, the monitor
is out of order.
Picture is scrambled
/ Check your graphics board manual for the
proper monitor setting on your Multiscan
17seII/20seII.
/ Check this manual and confirm that the
graphic 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.

Color is not uniform
/ Trip the u power switch once to activate the
Auto-degauss cycle. This function is to
demagnetize the metal frame of the CRT to
obtain neutral field for uniform color
reproduction. If a second degauss cycle is
needed, allow a minimum interval of 20
minutes for the best result.
You cannot adjust the monitor with the buttons on
the front panel
/ If the control lock is set to on, set it to off using
the OPTION OSD. (page 11)
You will be able to adjust the monitor.
White does not look white
/ Adjust color temperature using the OPTION
OSD. (page 9)
/ Check that the 5 BNC’s are connected in the
right order (from power cord side: Red-
Green-Blue-HD-VD).
Screen image is not centered or sized properly
/ Adjust centering, size or geometry using the
OSD. (page 7, 8)
/ 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 a tendency to
have this problem on higher refresh timings.
Edges of the image are curved
/ Adjust pincushion using the OSD. (page 8)
White lines show red or blue shades at edges
/ Adjust the convergence using the OSD.
(page 9)
Picture is fuzzy
/ Adjust the contrast and brightness using the
OSD (page 7).
/ Trip the u power switch once to activate the
Auto-degauss cycle. This function
demagnetizes the metal frame of the CRT to
obtain 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 convergence using the OSD.
(page 9)
/ (GDM-20SE2T only)
If the moire is cancelled on the OPTION OSD,
the picture may be fuzzy.
— Select “OFF” on the OPTION OSD.
(page 10)
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 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. 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
/ 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.
/ (GDM-20SE2T only)
Cancel the moire using the OPTION OSD.
(page 10)
May be modified according to the model.
Because of vibration and shock during
transportation, the aperture grille may
occasionally slip out of place and black stripes may
appear (GDM-20SE2T only)
/ Lightly pat the sides of the monitor.
Troubleshooting
• If the problem persists, call your authorized Sony 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.
