If the picture is flickering or fuzzy, press the AUTO button.
The monitor is automatically adjusted to match the signal
from the connected computer.
Further fine adjustments may be needed with some
computers.  In this case, manually adjust the monitor.

Press the AUTO button.
The monitor adjusts the pitch to match the input signal
so that the picture appears sharp, and fits the picture to
the center of the screen.

• This function is intended for use with a computer running

Windows or similar graphic user interface software that
provides a full-screen picture.  It may not work properly if the
background color is dark or if the input picture does not fill the
screen to the edges (such as an MS-DOS prompt). In this case, do
steps 1 to 3 of “Eliminating Flickering or Blurring Manually” to
display the test pattern, then press the AUTO button again.

• The screen may go blank for a few seconds while performing the

auto-sizing function. This is not a malfunction.

Adjust the Pitch and Phase by referring to “Eliminating
Flickering or Blurring Manually.”

Adjust using the CENTER OSD by referring to “Adjusting
the Picture Position.”

If a part of the screen is flickering or blurring, press the
AUTO button.  If this operation does not work, adjust the
Pitch and Phase as follows.
Once the pitch and phase are adjusted, they will be stored in
memory for the current input signal.

This monitor has factory preset modes for the most popular
industry standards for true “plug and play” compatibility.
(See Appendix for a list of the factory preset modes.)
When a new input signal is entered, the monitor selects the
appropriate factory preset mode and momentarily adjusts
the phase calibration to provide a high quality picture to the
center of the screen.  The calibration is stored in memory
and is immediately recalled whenever the same input signal
is received.
For input signals that do not match one of the factory preset
modes, the digital Multiscan technology of this monitor
performs all of the adjustments necessary to ensure that a
clear picture appears on the screen for any timing in the
monitor’s frequency range.  However, it may be necessary
to fine tune the vertical/horizontal centering.  Simply press
the AUTO button or adjust the monitor according to the
adjustment instructions.  The adjustments are stored
automatically as a user mode and recalled whenever the
corresponding input signal is received.

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

E

NERGY 

S

TAR, as well as the more stringent

NUTEK .
If the monitor is connected to a computer or video graphics
board that is VESA DPMS (Display Power Management
Signaling) compliant, the monitor will automatically reduce
power consumption in three stages as shown below.
You can set the delay time before the monitor enters the
power saving mode using the OSD. Set the time according
to “Setting the Power Saving Delay Time” on page 16.

*

Power consumption of the monitor only.  The figures in
parentheses are power consumption of the monitor including
the AC adapter.

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

the Environmental Protection Agency.

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

signal is cut and NO INPUT SIGNAL appears on the screen.
After the time set in “Changing the Power Saving Delay Time”
(page 16) has elapsed, the monitor enters the power saving
mode.

This section may help you isolate the cause of a problem
and as a result, eliminate the need to contact technical
support.

If there is something wrong with the input signal, one of the
following messages appears on the screen.  To solve the
problem, see “Trouble symptoms and remedies” on page 19.

“OUT OF SCAN RANGE” indicates that the input signal is
not supported by the monitor’s specifications.

“NO INPUT SIGNAL” indicates that no signal is input to the
monitor.

If the problem is caused by the connected computer or other equipment, please refer to the connected equipment’s instruction
manual.
Use the self-diagnosis function (page 20) if the following recommendations do no resolve the problem.

If the u indicator  is not lit

If the “NO INPUT SIGNAL”
message appears on the screen,
or if the u indicator is either
orange or alternating between
green and orange

If the “OUT OF SCAN RANGE”
message appears on the screen

If no message is displayed and
the u indicator is green or
flashing orange

If using Windows 95/98

If using a Macintosh system

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

• Check that the video signal cable is properly connected and all plugs are firmly seated in

their sockets.

• Check that the HD15 video input connector’s pins are not bent or pushed in.
p

• The computer is in power saving mode. Try pressing any key on the computer keyboard.
• Check that the computer’s power is “on.”
• Check that your graphics board is completely seated in the proper bus slot.

p

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

replaced an old monitor with this monitor, reconnect the old monitor and adjust the
frequency range to the following.
Horizontal: 30 – 61 kHz, Vertical: 50 – 75 Hz

• Use the self-diagnosis function (page 20).

• If you replaced an old monitor with this monitor, reconnect the old monitor and do the

following.  Install the Windows Monitor Information Disk/Utility Disk and select “CPD-
M151” from among the Sony monitors in the Windows 95/98 monitor selection screen.

• Check that the Macintosh adapter and the video signal cable are properly connected

(page 6).

• Press the AUTO button.  If this does not work, adjust the pitch and phase (page 12).
• Isolate and eliminate any potential sources of electric or magnetic fields such as other

monitors, laser printers, electric fans, fluorescent lighting, or televisions.

• Move the monitor away from power lines or place a magnetic shield near the monitor.
• Try plugging the monitor into a different AC outlet, preferably on a different circuit.
• Try turning the monitor 90

°

 to the left or right.

p

• Check your graphics board manual for the proper monitor setting.
• Confirm that the graphics mode (VESA, Macintosh 19” Color, etc.) and the frequency of

the input signal are supported by this monitor (Appendix). Even if the frequency is
within the proper range, some graphics boards may have a sync pulse that is too narrow
for the monitor to sync correctly.

• Adjust the computer’s refresh rate (vertical frequency) to obtain the best possible picture.

• Press the AUTO button.  If this does not work, adjust the pitch and phase (page 12).
• Adjust the contrast and brightness (page 14).

• Adjust the backlight (page 16)
• Adjust the brightness (page 14).
• It takes several seconds for the monitor to warm up after the power is turned on.  The

picture will appear momentarily.
