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 1600
x 900 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.
