Warning Signal
If you see warning messages on your LCD screen, this means that the LCD display
cannot receive a clean signal from the computer graphics card.
There may be three sources for this problem. Please check the cable connections or
contact your local dealer or our service center for more information.
No Signal
This message means that the LCD Display has been powered on but it
cannot receive any signal from the computer graphics card. Check all the
power switches, power cables and VGA signal cable.
Going to Sleep
The LCD is under the power saving mode. In addition, the LCD will go into
this sleep mode when experiencing a sudden signal disconnecting
problem.
Out of Range
This message means that the signal of the computer graphic card is not
compatible with the LCD display. When the signal is not included in the
“Video Modes” list we have listed in the Appendices of this manual, the
LCD monitor will display this message.
