fields such as other monitors, laser printers, electric fans, fluorescent
lighting, or televisions.
• Move the monitor away from power lines or place a magnetic shield
near the monitor.
• Try plugging the monitor into a different AC outlet, preferably on a
different circuit.
• Try turning the monitor 90° to the left or right.
• Check your graphics board manual for the proper monitor setting.
• Confirm that the graphics mode and the frequency of the input signal
are supported by this monitor (see "Preset mode timing table" on
page i). 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.
x Picture is fuzzy
• Adjust the brightness and contrast.
• Degauss the monitor.*
• Adjust the degree of moire cancellation until the moire is minimal.
x Picture is ghosting
• Eliminate the use of video cable extensions and/or video switch
boxes.

x Picture is not centered or sized properly
• Adjust the size or centering. Note that with some input signals and/
or graphics boards the periphery of the screen is not fully utilized.
• Just after turning on the power switch, the size/center may take a
while to adjust properly.

• Degauss the monitor.* If you place equipment that generates a
magnetic field, such as a speaker, near the monitor, or if you change
the direction the monitor faces, color may lose uniformity.
x White does not look white
• Adjust the color temperature.
x A hum is heard right after the power is turned on
• This is the sound of the auto-degauss cycle. When the power is
turned on, the monitor is automatically degaussed for a few seconds.
* If a second degauss cycle is needed, allow a minimum interval of
20 minutes for the best result. A humming noise may be heard, but this is
not a malfunction.
