A column driver system and method for driving a plurality of column drivers in an active matrix display. The system comprises: a register in each column driver for holding a pixel value; a system that generates a shared ramp signal for the plurality of column drivers; a system that samples the shared ramp signal for each possible pixel value; and a load characteristic correction system that adaptively adjusts the shared ramp signal in anticipation of a load error associated with at least one pixel value. The load characteristic correction system comprises: a data collection system that collects pixel data for each of the plurality of column drivers and determines a number of occurrences of all possible pixel values; a load analysis system that identifies error conditions based on the number of occurrences; and a signal modification system that determines a correction to the ramp signal when an error condition is identified.
