Useful Tips
A monitor recreates visual signals received from the PC. Therefore, if there is trouble with the PC or
the video card, this can cause the monitor to become blank, have poor coloring, noise, Video mode
not supported, etc. In this case, first check the source of the problem, and then contact a service
center or your dealer.
Judging the monitor's working condition
If there is no image on the screen or an “Video mode not supported” 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.
