Warning Signal
If you see warning messages on your screen, this means that the display cannot receive a clean signal from the computer graphics card.
Below are the three kinds of warning signals you may receive. Please check the cable connections or contact your sales representative or our service center for more information.
No Signal
This message means that the 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 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 monitor will display this message.
