    pls help, this is my first mbp but i m quite frustrated

    i m using LG22inch monitor, it is a vga cable connected to a dvi adapter connected to a dvi miniport.

    initially i tried to plug it in without AC power, but ext monitor screen is black. I surfed the net for some solutions, it says tat the AC power must be plugged in for the external monitor to work.

    However, when i plug in AC power, the ext monitor is still sleeping, even though i can detect it in my profile settings.. what can i do to wake it up??

    Please help!!

    AFAIK the DVI adapter does not pass an analog signal since it is not present to begin with. You need to use a mini-DisplayPort to VGA adapter instead.
