ABSTRACT:
A display controller in a computer system controls the asynchronous output of graphics display data in a computer system having at least one fixed resolution flat panel display. Fixed panel displays may have problems displaying non-native resolutions particularly at lower resolutions. The controller of the present invention uses a time base converter, horizontal and vertical Discrete Time Oscillators (DTO), and polyphase interpolator, which may be Discrete Cosine Transform (DCT)-based to expand graphics display data asynchronously from native resolution to at least one resolution suitable for display on a fixed resolution panel. Graphics data may also be output asynchronously to a CRT. Time base converter receives frequency related input parameters and generates at least one asynchronous output at the desired output resolution.
