    You didn't specified whether you are refering to LCD/TFT/CRT monitor. In case of CRT monitor, I think that the below discussion is useful.
    In CRT, the image is produced by scanning the entire screen using the electron beam, produced using the hot cathode. The direction of this beam can be controlled using magnetic fields, strong enough to deflect it to the desired direction.
    This is done by the vertical/horizontal deflection coils which you can find on the yoke of your monitor or simply, your TV. The horizontal and vertical ossilators produce the signals needed for deflection that is feeded to the deflection coils.
    If you want to attract the beam, you have to produce a possitive field, and vice versa. Thus by using appropriate signals on both the horizontal and vertical deflection coils, you can position the beam to the desired point on the screen.
    The screen contains a type of phospher coated in the inner side. So when an electron beam falls on it, it will produce the light equivalent on the other side.
    Search google for more information..
