Interfacing a digital display card through PCI express connector

摘要

An embodiment of the present invention is a technique to interface a display card through an interface connector. A video output device on the display card generates digital video output signals from a graphics chipset on a motherboard. The card is plugged into an interface connector on the motherboard. The interface connector is compatible with a first interface standard. The video output device is compatible to a second interface standard. A card detector is coupled to the video output device and the interface connector to enable the video output device if the graphics chip set supports the video output device.
