Warning Messages
If there is something wrong with the input signal, a message appears on the screen or the
screen goes blank although the power indicator LED is still on. The message may indicate
that the monitor is out of scan range or that you need to check the signal cable.
Environment

another room.

feet (one meter) of the monitor.
Useful Tips
A monitor recreates visual signals received from the computer. Therefore, if there is a problem
with the computer or the video card, this can cause the monitor to become blank, have poor
coloring, become noisy, and video mode not supported, etc. In this case, first check the source
of the problem, and then contact the Service Center or your dealer.
Judging the monitor's working condition
If there is no image on the screen or a "Not Optimum Mode", "Recommended Mode 1680
x 1050 60 Hz" message comes up, disconnect the cable from the computer while the monitor
is still powered on.
If there is a message coming up on the screen or if the screen goes white, this means the
monitor is in working condition.
In this case, check the computer for trouble.
