    About the VGA Video Circuitry The Headland Technologies HT216 VGA controller circuitry on the fvlSL486 uses local bus technology to bypass the standard AT bus. By eliminating the need to use the slower 8 MHz bus, the VGA system delivers fast VGA graphics with speeds approaching those of expensive co-processor based add-in cards.

    overview Section 2 Monitor Compatibility The liT216 works with all fixed and variable-frequency analog monitors compatible with the IBM PS/2 analog monitors. The video resolution you can get from the circuitry depends on the monitor you have. For exam- ple, some monitors do not work at resolutions higher than 640x480 because they cannot use the vertical and horizontal scan rates required for higher resolu- tions.
