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 are three kinds of sources for this problem. Please check the cable
connections or contact Planar 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, VGA, DVI or Video signal cables.
Going to Sleep
This message means that the LCD display is under the power saving mode. In
addition, the LCD display will enter the sleeping mode when experiencing a
sudden signal disconnecting problem.
Unsupported Mode
This message means that the signal of the computer graphics card or video
source is not compatible with the LCD display. The LCD display will show this
message when the signal is not included in the Signal Compatibility mode tables
listed in the Appendix of this manual.
