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 1440 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.
