A.2 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.
Below are the three kinds of Warning Signal. 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/DVI signal cable.
Going to Sleep
The LCD display is under the power saving mode. In addition, the LCD display will
enter power saving mode when experiencing a sudden signal disconnecting problem.
The monitor can be activated by pressing any keyboard, triggering the mouse or
touching the screen.
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.
