This function gives warning message about input resolution or
refresh rate that the monitor cannot support. When an input
signal which is out of the normal operation range defined in
Section 3.2. Then the monitor will display “Input not supported”
message:
1. Pixel clock frequency : Fc>165(Digital)
Fc>205 (Analog)
2. V-sync frequency: 50Hz>F V>=76Hz
3. H-sync frequency: 30KHz>FH>83KHz(Analog);
30KHz>F H>83KHz(Digital)

cable Menu
This function gives warning message when the VGA cable is
not connected. When the Monitor detected that the VGA cable
is not connected to the monitor. The OSD shall display a
message “Cable not connected” all the time to alert the user
