The sRGB color setting is an industry standard color space 
protocol designed to correlate the displayed and printed colors of 
sRGB compliant computer products. To adjust the colors to the 
sRGB profile, simply select the sRGB mode in the COLOR menu.
Once you select the sRGB mode, the brightness (

) and 

contrast (6) values are automatically set to the values to be set in 
the sRGB mode.

In order to display the sRGB colors correctly (

γ

 = 2.2, 6500K), 

confirm that:
• the brightness (

) and contrast (6) values are adjusted 

respectively to the numbers shown in the BRIGHTNESS/
CONTRAST menu. If not, press the RESET button (for less 
than 2 seconds). For information on how to change the 
brightness and contrast, see “Adjusting the brightness and 
contrast” on page 11.

• the color settings of your computer are set to the sRGB profile.

Your computer and other connected products (such as a printer), must be 
sRGB compliant.

The colors of most display monitors tend to gradually lose brilliance 
over several years of service. The IMAGE RESTORATION feature 
found in the EASY and sRGB menus allows you to restore the color 
to the original factory quality levels.

The picture disappears while the color is being restored (about 
2 seconds). After the color is restored, the picture reappears 
on the screen again.

• Before using this feature, the monitor must be in normal operation 

mode (green power indicator on) for at least 30 minutes. If the monitor 
goes into power saving mode, you must return the monitor to normal 
operation mode and wait for 30 minutes for the monitor to be ready. 
You may need to adjust your computer’s power saving settings to keep 
the monitor in normal operation mode for the full 30 minutes. If the 
monitor is not ready, the following message will appear.

• The monitor may gradually lose its ability to perform this function due 

to the natural aging of the picture tube.

The SCREEN settings allow you to adjust the quality of the 
picture by controlling the moire and landing.
• If the color is irregular at the corners of the screen, adjust the 

landing.

• If elliptical or wavy patterns appear on the screen, cancel the 

moire.

The CANCEL MOIRE and MOIRE ADJUST settings are stored 
in memory for the current input signal. All other settings are 
stored in memory for all input signals.

The main MENU appears on the screen.

The SCREEN menu appears on the screen.

* Moire is a type of natural interference which produces soft, wavy lines 

on your screen. It may appear due to interference between the pattern 
of the picture on the screen and the phosphor pitch pattern of the 
monitor.

The picture may become fuzzy when CANCEL MOIRE is set to ON.

The CONV settings allow you to adjust the quality of the picture 
by controlling the convergence. The convergence refers to the 
alignment of the red, green, and blue color signals.
If you see red or blue shadows around letters or lines, adjust the 
convergence.
These settings are stored in memory for all input signals.

cycle is needed, allow a minimum interval of 20 minutes for the 
best result.

This monitor has the following three reset methods. Use the 
RESET button to reset the adjustments.

x

Use the joystick to select the adjustment item you want to reset, 
and press the RESET button.

x

Press the RESET button when no menu is displayed on the screen. 
Note that the following items are not reset by this method:
• on-screen menu language (page 8)
• adjustment mode in the COLOR menu (EASY, EXPERT, 

sRGB) (page 12)

• on-screen menu position (page 15)
• control lock (page 15)

x

Press and hold the RESET button for more than 2 seconds.

The RESET button does not function when 

 (CONTROL LOCK) is 

set to ON.

When the monitor receives an input signal, it automatically 
matches the signal to one of the factory preset modes stored in the 
monitor’s memory to provide a high quality picture at the center of 
the screen. (See Appendix for a list of the factory preset modes.) 
For input signals that do not match one of the factory preset modes, 
the digital Multiscan technology of this monitor ensures that a 
clear picture appears on the screen for any timing in the monitor’s 
frequency range (horizontal: 30 – 121 kHz, vertical: 48 – 160 Hz). 
If the picture is adjusted, the adjustment data is stored as a user 
mode and automatically recalled whenever the same input signal 
is received.

For Windows users, check your graphic board manual or the 
utility program which comes with your graphic board and select 
the highest available refresh rate to maximize monitor 
performance.

This monitor meets the power-saving guidelines set by VESA, 

E

NERGY 

S

TAR, and NUTEK. If the monitor is connected to a 

computer or video graphics board that is DPMS (Display Power 
Management Signaling) compliant, the monitor will automatically 
reduce power consumption in three stages as shown below.

*

Figures reflect power consumption when no USB compatible 
peripherals are connected to the monitor.

** “Sleep” and “deep sleep” are power saving modes defined by the 

Environmental Protection Agency.

*** When your computer enters power saving mode, the input signal is 

cut and NO INPUT SIGNAL appears on the screen before the 
monitor enters active off mode. After a few seconds, the monitor 
enters power saving mode.

Before contacting technical support, refer to this section.

The visible lines on your screen especially when the background 
screen color is light (usually white), are normal for the Trinitron 
monitor. This is not a malfunction. These are shadows from the 
damper wires used to stabilize the aperture grille. The aperture 
grille is the essential element that makes a Trinitron picture tube 
unique by allowing more light to reach the screen, resulting in a 
brighter, more detailed picture.

If there is something wrong with the input signal, one of the 
following messages appears on the screen.

1

This indicates that no signal is input from the selected connector.

1

This indicates that the input signal is not supported by the 
monitor’s specifications.

For more information, see “Trouble symptoms and remedies” on 
page 18.

While the monitor is receiving a video signal, press and hold the 
joystick for more than 5 seconds to display this monitor’s 
information box.

If the problem persists, call your authorized Sony dealer and give 
the following information.
• Model name: GDM-FW900
• Serial number
• Name and specifications of your computer and graphic board.

2

This message shows the currently selected connector 
(INPUT 1 or INPUT 2).

One or more of the following messages may appear on the 
screen.
• If ACTIVATE BY COMPUTER appears on the screen, try 

pressing any key on the computer or moving the mouse, and 
confirm that your computer’s graphic board is completely 
seated in the correct bus slot.

• If CHECK INPUT SELECTOR appears on the screen, try 

changing the input signal (page 9).

• If CHECK SIGNAL CABLE appears on the screen, check 

that the monitor is correctly connected to the computer 
(page 6).
