1. A method for providing a load/reset sequence for a display system having a phased reset spatial light modulator having pixels addressable with data by means of loads and resets and having a minimum load-time, the data being formatted in bit-planes, the bit-planes each loaded as one or more segments in a predetermined sequence during a frame-time, the method comprising:

  • storing a display order of the segments;

    determining whether resetting any of the segments conflicts with the resetting of another of the segments, thereby identifying a conflicting segment;

    skewing the display time of the conflicting segment to avoid the reset conflict;

    identifying in the sequence a segment before and a segment after the conflicting segment each affected by the skewing of the conflicting segment, wherein the segments before and after the conflicting segment are each of respective bit-planes comprising multiple segments in the sequence;

    counter-skewing the display times of segments respectively corresponding to the segments before and after the conflicting segment; and

    setting start times for each load and reset of each of the segments.
