An improved display system includes LED light sources for providing red, green, and blue light. A controller for the display system includes a sequencer that controls the timing and sequence of image data to a spatial light modulator (e.g., a DMD) and activation of the light sources. The sequencer can control the timing and sequence of the light sources according to a display mode that can include such things as white point information, color-look information, timing of PWM sequences, and/or color cycle rate information. The display mode can be set during manufacturing or can be programmable. In some embodiments, the controller can include memory for storing multiple display modes and a user can select among the display modes to change the look of a displayed image. In some embodiments, a programming device can be provided allowing a user to customize the display modes.
