Hi Kelvin -
The Voodoo2 is a 3D-only card, used only for full-screen applications
(usually known as games). To a DirectX programmer it appears as a DirectX
display that has no corresponding desktop. The card is designed to be
daisy-chained with the primary graphics card; normally the primary card
video signal will be passed through to the output, but when an application
activates the Voodoo2 it produces its own video signal. Two cards, one
monitor.
Voodoo2 is an old card (1996?) but there are still quite a few of
them in use. 3dfx sold millions of these things.
