Power Saving Function
This monitor meets the power-saving guidelines set by
VESA and Energy Star, 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 15.
Note
If no video signal is input to the monitor, the “NO INPUT
SIGNAL” message (page 18) appears. After the delay time has
passed, the power saving function automatically puts the monitor
into the active-off mode and the
u
indicator lights up orange. Once
the horizontal and vertical sync signals are detected, the monitor
automatically resumes its normal operation mode.
Damper Wires
When viewing a white background, very thin horizontal
lines may be visible on the screen as shown below. These
lines are the shadows of the damper wires and are
characteristic of CRTs that use aperture grilles. The wires
are attached to the aperture grille on the inside of the
Trinitron tube and prevent the vibration of the aperture
grille.

Plug & Play
This monitor complies with the DDC
1, DDC2B, DDC2AB
and DDC2B+ 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, DDC2AB or DDC2B+ host system is
connected, the monitor automatically switches to the
appropriate standard.

Association.

Additional Information
Warning Messages
If there is something wrong with the input signal, one of the
following messages appears.
Additional Information
1
The input signal condition
“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, or
the input signal from the selected input connector is not
received.
2
The selected input connector
Indicates which input connector is receiving the wrong
signal. If there is something wrong with the signal from
both input connectors, “1” (HD15) and “2” (5BNC) are
displayed alternately.
To solve these problems, see “Troubleshooting” below.
Troubleshooting
This section may help you isolate the cause of a problem and as a result, eliminate the need to contact technical support.

• Check that the power cord is properly connected.
• Check that the
u
(power) switch is in the “on” position.
• The screen is blank when the monitor is in power saving mode. Try pressing any key on the
computer keyboard.
• Check that your computer power switch is in the “on” position.
• Check that the input select setting is correct.
• Check that the video signal cable is properly connected and all plugs are firmly seated in
their sockets.
• Check that the 5 BNCs are connected in the correct order (from left to right: 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 completely seated in the proper bus slot.
• Check that the video frequency range is within that specified for the monitor.
(Horizontal: 30 – 107 kHz, Vertical: 48 – 160 Hz)
Refer to your computer‘s instruction manual to adjust the video frequency range.
• If you are using a video signal cable adapter, check that it is correct.
• See “Self-diagnosis Function” (page 20).
• Check your graphics board manual for the proper monitor setting.
• Check this manual and confirm that the graphics mode and the frequency you are trying to
operate at is supported. Even if the frequency is 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 14).
If you place equipment which generates a magnetic field, such as a loudspeaker, near the
monitor, or you change the direction of the monitor, color may lose uniformity.
The degauss function demagnetizes 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 (pages 12 – 13).
