ABSTRACT:
A graphics pipeline for use with a high resolution display is disclosed. The graphics pipeline comprises a frame buffer configuration. The frame buffer configuration includes a first mode area and a second mode area. The graphics pipeline further includes a display pipeline for obtaining data from the frame buffer configuration. The display pipeline includes a controller. The controller provides pixels from the first mode area to the display as is. Finally, the controller expands pixels from the second mode area and provides the expanded pixels to the display. Accordingly, a system and method in accordance with the present invention solves the GUI problem (small icon and small menu text) of high resolution display by allowing the 3D Graphics Window to display fine pitch pictures while being able to display images in the 2D graphics window in a useable form. The system and method in accordance does not depend on the types of drawing objects (line or surface), drawing order, and crossover.
