Abstract

Disclosed is a new connector that allows VGA connectivity on motherboards designed for the new digital video connector. Digital video is here and the days of the 15 pin VGA connector are numbered. The 15 VGA connector has been used in personal computers for about 15 years. It is used to connect analog monitors to the system unit. Many manufactures of personal computers have gotten together and defined a new digital connector. This connector is called the DVI connector. DVI stands for Digital Video Interface. One version is digital only, DVI-D. The other version is digital and analog, DVI-I. I stands for integrated. Integrated analog and digital. The analog section has the same signals as the 15 pin VGA connector. The digital portion uses transition minimized differential signaling. Most personal computers built in 1999 will have the VGA connector. Only a few will have the DVI connector. As time goes on more and more will be built with the DVI connector. To connect an older analog VGA type monitor to the DVI-I connector, an adapter will be required. The analog VGA monitor will not work with a system that only has the DVI-D connector. There will be a few years of transition from the VGA connector to the DVI connector. During this time period many manufactures of personal computers will want to offer systems with either of the connectors. To do this they can design two different motherboards one with each connector. Many companies will chose to save development cost and only use the DVI-I connector and use an adapter if the customer wants to use a VGA type monitor. They can also use this invention. This invention allows companies to develop one system board with the DVI-I connector footprint. This invention is a connector with the DVI-I foot print and a VGA output.
