• 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 – 61 kHz (SDM-HS53), 28 – 80 kHz (SDM-HS73/HS93)
Vertical: 48 – 75 Hz
If you are using Windows and

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