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 may be two 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, and VGA signal cable.
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 display will display this message.
