If using Windows 95/98/2000 • If you replaced an old monitor with this monitor, reconnect the old monitor and do the
following. Select “SONY” from the “Manufactures” list and select “SDM-M51” from the
“Models” list in the Windows 95/98/2000 device selection screen. If “SDM-M51” does

Macintosh adapter and the video signal cable are properly connected (page 7).
• If you connect to the other version of Macintosh series computer that has 2 rows of pins,

x Problems caused by the connected computer or other equipment
• 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 graphic 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.
