ABSTRACT:
A video controller which can be programmed to generate horizontal and vertical blanking and synchronization signals for driving video monitors having different resolutions or operating frequencies includes storage registers for receiving and storing pixel count information associated with the beginning of horizontal blanking, the beginning of horizontal synchronization, the end of horizontal blanking, the end of horizontal synchronization and line count information associated with the beginning of vertical blanking, the beginning of vertical synchronization, and the end of vertical synchronization. The controller further includes circuitry for counting pixels as they are provided by the controller to the monitor and circuitry for counting horizontal scan lines. Properly timed blanking and synchronization signals are generated by comparing pixel count and line count information to the stored pixel and line count values.
