The following table summarizes the results of displaying different image formats using the different display drivers. When evaluating images for use with alternate display drivers, look carefully at color, resolution, and scale shifts. For example, displaying a 256-color image with a 16-color driver might produce unsatisfactory results. Changing the display resolution can also produce some startling results. For example, without cropping or scaling an image, the low-resolution driver will display only one-quarter of a full-screen, high-resolution image.
