PROBLEM
There is no picture on LCD Monitor
If you have chosen an output timing that is outside of the LCD Monitor’s synchronous
range (Horizontal: 24 ~ 80 KHz and Vertical: 56 ~ 75 Hz), the OSD will display an “Input
Signal Out of Range” message. Choose a mode that is supported by the LCD Monitor.
If there is no signal input or you get a DPMS power saving signal from the PC, the
monitor will display the message “No Input Signal”, and then go into the POWER OFF
mode.
If the signal cable is not connected to the monitor, the monitor will display the message
“Check Video Cable”, and then go into POWER OFF mode.
