  • Patent number: 5608418
    Abstract: A computer graphics subsystem is disclosed that renders images on either a high resolution CRT display or a high resolution flat panel display without requiring modifications to existing application programs. The graphics subsystem includes a ramdac circuit that generates a set of video sync signals for a CRT display. The ramdac circuit has an analog video port and a digital pixel output port. The ramdac circuit performs color look-up table and digital to analog conversion functions to drive a high resolution CRT display through the analog video output port. The ramdac circuit uses the digital pixel port to enable the computer graphics subsystem to drive a flat panel display. A color buffer circuit converts the video sync signals into a set of flat panel sync signals for a flat panel display.
