A method for reducing cross-talk on a liquid crystal display begins by receiving pixel data defining an image comprising a plurality of pixels; the received pixel data includes an intensity value associated with each pixel. The image is compressed by reducing the range of the intensity values of all the pixels in the image; the compressing step comprising arithmetically adjusting the intensity values of the pixels. Lines in the compressed image that are disposed to create cross-talk are identified. The image is then decompressed by applying a scale factor to the adjusted intensity value associated only with the pixels in the identified lines. The scale factor is selected such that a display image rendered on a liquid crystal display from the pixel data of the decompressed image has less cross-talk than a display image rendered on a liquid crystal display from the received pixel data.
