ABSTRACT:
A system and method for automatically-calibrating display monitor beam currents. A device selects a target beam current within a display monitor. A current sampler measures a present beam current within the display monitor. A beam current controller increases a gain of an amplifier within the monitor by a delta value if the present beam current is less than the target beam current, and decreases the gain of the amplifier by the delta value if the present beam current is greater than the target beam current. A first step in the method selects a target beam current. A second step measures a present beam current generated by an amplifier. A third step increases a gain of the amplifier by a delta value if the present beam current is less than the target beam current. A fourth step decreases the gain of the amplifier by the delta value if the present beam current is greater than the target beam current. A fifth step sets a multiplier to a predetermined value. A sixth step multiplies the delta value by the multiplier. A seventh step reduces the multiplier by a predetermined amount if the present beam current crosses the target beam current.
