is pressed,
If the 1 (power) indicator turns on

Check these items
• Check that the power cord is properly connected.
• Check that the monitor's MAIN POWER switch is on (page 9).
• Check that the 1 (power) switch is on.
• Check that the video signal cable is properly connected and all plugs are firmly seated in
their sockets (page 6).
• Check that the video input connector's pins are not bent or pushed in.
• Check that the input select setting is correct (page 10).
• A non-supplied video signal cable is connected. If you connect a non-supplied video
signal cable, CABLE DISCONNECTED may appear on the screen. This is not a
malfunction.
• Check that the video signal cable is properly connected and all plugs are firmly seated in
their sockets (page 6).
• Check that the video input connector's pins are not bent or pushed in.
• Check that the input select setting is correct (page 10).
x Problems caused by a computer or other equipment connected, and not
caused by the monitor
• The computer is in the power saving mode. Try pressing any key on the keyboard or
moving the mouse.
• Check that your graphics board is installed properly.
• Check that the computer's power is on.
• Restart the computer.
x Problems caused by a computer or other equipment connected, and not
caused by the monitor
• 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
computer's graphics board within the following ranges:
Horizontal: 28 – 80 kHz (analog RGB), 28 – 64 kHz (digital RGB)
Vertical: 48 – 75 Hz (analog RGB), 60 Hz (digital RGB)
Resolution: 1280 × 1024 or less (SDM-S74/SDM-S94)
• If you replaced an old monitor with this monitor, reconnect the old monitor and do the
following. Select "SONY" from the "Manufacturers" list and select "SDM-S74" or
"SDM-S94" from the "Models" list in the Windows device selection screen. If the model
name of this monitor does not appear in the "Models" list, try "Plug & Play."
• When connecting a Macintosh computer, use an adapter (not supplied) if necessary.
Connect the adapter to the computer before connecting the video signal cable.
• Adjust the pitch and phase (analog RGB signal only) (page 13).
• Try plugging the monitor into a different AC outlet, preferably on a different circuit.
• Change the orientation of the monitor.
x Problems caused by a computer or other equipment connected, and not
caused by the monitor
• 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. 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.
• This monitor does not process interlace signals. Set for progressive signals.
• Adjust the computer's refresh rate (vertical frequency) to obtain the best possible picture.
