Disclosed is a computer having a display controller for controlling a display where the display provides an image with different selectable gray scale levels. The display controller includes a pattern unit for providing modulation patterns. The modulation patterns include patterns each formed of sequences of different numbers of both 1's and 0's that are not phase related. The display controller additionally includes a modulation unit, operable over the sequential frames, for modulating the data values of pixels with the patterns whereby the intensity level of the pixels over the sequential frames is controlled as a function of the data value of the pixels and as a function of the patterns.
