•

Check your graphics board manual for the proper monitor setting.

•

Check this manual and confirm that the graphics mode and the frequency you are

trying to operate at is supported. Even if the frequency is within the proper range,

some video boards may have a sync pulse that is too narrow for the monitor to sync

correctly.

Color is not uniform

•

Degauss the monitor (page 13).

If you place equipment which generates a magnetic field, such as a loudspeaker, near

the monitor, or you change the direction of the monitor, color may lose uniformity.

The degauss function demagnetizes the metal frame of the CRT to obtain a neutral

field for uniform color reproduction. If a second degauss cycle is needed, allow a

minimum interval of 20 minutes for the best result.

You cannot adjust the

monitor with the buttons on

the front panel

•

If the control lock function is set to on, set it to off using the OPTION OSD (page 14).
