The present application describes a system and method for selecting the best modulation sequence for an image (e.g., video, graphics or the like) on a frame-by-frame basis to optimize the system contrast ratio, brightness and black level based on a histogram of pixels in each frame. Embodiments described in this application include Pulse-Width Modulation (PWM) display systems such as DMD(TM). In an embodiment, the present invention uses the histogram of pixels in each frame of an image to select alternate color sequences for each frame of the image wherein the alternative color sequence includes reduced number of bits for color representations than the original color sequence.
