❐ Is the power indicator light

❐ Is the power on and the
power indicator green?
❐ Is the power indicator

❐ Do you see an "OUT OF
FREQUENCY" message
on the screen?
❐ Do you see a "SELF
DIAGNOSITICS" message
on the screen?
The screen is flickering.
❐ Is the vertical frequency
less than 70Hz or is your
monitor set to the
interlaced mode?
❐ Do you have any
magnetic material such
as adapter, or high-
voltage line near to your
monitor?
❐ Do you hear a "~ding"

• Check and see if the power cord is connected properly to
the power outlet.
• Press the Power button.
• Adjust the brightness and the contrast.
• If the monitor is in power saving mode, try moving the
mouse or pressing any key on the keyboard to bring up
the screen.
• This message appears when the signal from the PC
(video card) is out of horizontal or vertical frequency range
of the monitor. See the ' S pecifications' section of this
manual and configure your monitor again.
• This message appears when the signal cable between
your PC and your monitor is not connected. Check the
signal cable and try again.
• Set the vertical frequency to 72Hz or higher, and
consult the video card user manual for instructions on
converting to a non-interlaced mode.
(You can set this option under the Display icon of the
Control Panel.)
• Remove magnetic sources, such as power adapters,
speakers, or high-voltage lines, away from the
monitor.
• Use the normal degaussing function. This function
clears the screen and reduces any screen blur that
may occur due to the surrounding magnetic field. The
screen may flicker for about 5 seconds, accompanied
by a "~ding" sound.
