• Check that the input select setting is correct (page 11).
• 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.

their sockets (page 7).
• Check that the video input connector's pins are not bent or pushed in.
• Check that the input select setting is correct (page 11).
x Problems caused by a computer or other equipment connected, and not
caused by the display
• 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 display
• Check that the video frequency range is within that specified for the display. If you
replaced an old display with this display, reconnect the old display 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
• If you replaced an old display with this display, reconnect the old display and do the
following. Select "SONY" from the "Manufacturers" list and select the desired model
name from the "Models" list in the Windows device selection screen. If the model name of
this display 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 14).
• Try plugging the display into a different AC outlet, preferably on a different circuit.
x Problems caused by a computer or other equipment connected, and not
caused by the display
• Check your graphics board manual for the proper display setting.
• Confirm that the graphics mode (VESA, Macintosh 19" Color, etc.) and the frequency of
the input signal are supported by this display. Even if the frequency is within the proper
range, some graphics boards may have a sync pulse that is too narrow for the display to
sync correctly.
• This display does not process interlace signals. Set for progressive signals.
• Adjust the computer's refresh rate (vertical frequency) to obtain the best possible picture.
