Displays systems and methods for dithering input image data to reduce quantization errors in a display system include inputting input image data to be rendered by said display system; applying a gamma table to the input image data to create a first intermediate image data; applying a dithering pattern, the dithering pattern comprising a checkerboard pattern, the checkerboard pattern depending upon the subpixel layout of the display. The display system may include a separate gamma table for each input color channel and apply the separate gamma table to perform white point adjustments for the display system.
