Goes like this: Any mid- to high-end video card has outputs for both analog VGA (the 15-pin dsub we're all familiar with) and newer "DVI" output designed for LCD panels.
The signals from a DVI port can, however, be easily converted to analog VGA for use with a regular connector and in fact most video cards come with such an adapter. And on most video cards that have these two ports they are seen as seperate video devices.
The Nvidia Geforce ti4000 and fx5000 series supports this as well as the newer ATI Raedeons, or at least their chips do -- it also depends on how the card manufacturer wants to have things configured.
