    The formula for power states that:

    P (Watts) = V(olts) x I (amps).

    Thus, 500 mA (.5A) x 12V = 6 Watts, well below what your monitor is asking for.

    For what you need, reverse the equation:

    9.5W / 12V = 0.79166666666666666666666666666667 (according to Windows' calculator)

    Get a supply rated for at least 800mA, or 1A (1000mA) to be on the safe side.
