ABSTRACT:
A video display controller capable of providing video control information for either a flat panel or a CRT display. The controller includes a plurality of main circuits, alternate circuits, select circuits, and a circuit for identifying the display device used in the system. Each main circuit receives information from the processor and generates main video information compatible with a CRT. Each alternate circuit receives information from the processor and generates alternate video information compatible with a flat panel display. Each select circuit receives main and alternate video information and outputs main video information when the display device is a CRT display and the alternate video information when the display device is a flat panel display. In one embodiment, the alternate circuits are programmable registers. In another embodiment, tables are used to program the alternate registers to provide compatibility for a number of possible display devices.
