ABSTRACT:
A method for improving compatibility between an application program and a display device of a computer system includes: providing a first format in a first frame buffer, the first format compatible with a format for an application program, providing a second format in a second frame buffer, the second format compatible with a format for an output device, and transforming inputs from the application program from the first format in the first frame buffer to the second format in the second frame buffer for output on the output device. With the present invention, new formats can be developed to reduce costs and improve performance with transparent compatibility for programs developed to correspond with old formats. Thus, improved flexibility for supporting a variety of formats developed for differing memory depths, differing resolutions, and differing color formats is realized.
