1. A method comprising:
configuring a digital light projector of a display device to generate only a single red-green-blue color sequence repetition per image frame;
identifying a color sequence of a light source component of the digital light projector;
replacing a default pixel persistence value of the digital light projector with a reduced pixel persistence value for all image frames, the reduced pixel persistence value indicating a length of time each pixel of the digital light projector remains lit, the reduced pixel persistence value being less than the default pixel persistence value;
tracking a motion of the display device; and
adjusting an operation of the digital light projector based on the single red-green-blue color sequence repetition, the color sequence, and the motion of the display device by shifting each bit plane of each color plane individually based on the adjusted reduced pixel persistence value.
