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 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.
