xrandr doesn't detect vga cable connected: VGA-0 disconnected

I try to connect my notebook acer aspire 5920g to my monitor samsung syncmaster 710mp but when i try to run xrandr it shows me that the vga-0 output is disconnected which means that the cable is disconnected, but the cable is connected and monitors light is blinking.

xrandr --verbose

output:
