Warning Signal
There are instances when you will see warning messages from the LCD screen.
This occurs when the LCD is unable to receive the exact signal from the com-
puter graphic card.
There are three instances when this may happen. Please check the cable con-
nections or contact your local dealer or Planar Support for more.
No Signal
The LCD has been powered on but it isn’t receiving a signal from
the computer graphic 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 sleeping mode when experiencing a sudden signal dis-
connecting problem.
Unsupport Mode
The signal of the computer graphic card is incompatible with the
LCD. This occurs when the graphic card signal is not one of the
compatibility modes listed in the Appendices of this manual.
