Secondary displays require both hardware and driver support; some graphics cards may support overlay on the second display while their drivers may not yet support it (note: recent (July 2008) graphics chipset driver bugs can cause most video formats apart from mpeg2 to work on both monitors, and mpeg2 only on the primary with most players).

Previously, graphic cards were also called graphic adapters, and the chips used on these ISA/EISA cards consisted solely of a display controller, as this was the only functionality required to connect a computer to a display. Later cards included ICs to perform calculations related to 2D rendering in parallel with the CPU; these cards were ...

The ATI Twin Wonder TV tuner card. A TV tuner card is a kind of television tuner that allows television signals to be received by a computer.Most TV tuners also function as video capture cards, allowing them to record television programs onto a hard disk much like the digital video recorder (DVR) does.
The AIW card drivers are based on ATI's Catalyst drivers with additional T200 unified stream drivers. Currently, the only operating systems fully supporting TV capture with these cards are Microsoft Windows XP, 2000, 98, and 95. Display drivers work on Linux, and TV capture is supported on some cards with the GATOS project. [4]
