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.
