The Difference Between DVI-I and DVI-D on an NVIDIA Based Graphics Card

Most of the contemporary NVIDIA based graphics cards come featuring the DVI or Digital Video Interface connector in order to connect a project or a digital flat LCD monitor to the graphics card. The colour of the DVI connector and VGA connector helps in identifying the difference between the DVI or VGA connectors. The DVI connectors are coloured with white whereas the VGA connectors are blue. Similarly, the graphics cards featuring DVI connectors also can be determined by the pins of DVI connectors. However, the layout of the pins as well as the numbers of the pins in the DVI connectors vary depending on the type of the graphics card. Get into in order to avail the appropriate DVI connectors that are compatible for your NVIDIA graphics card.

You can get two basic types of DVI connectors in the contemporary market, the DVI-I and the DVI-D connectors. The DVI-D connectors send only digital signals whereas the DVI-I is capable of sending both digital signals for digital display devices such as the flat panel LCD monitors as well as analog signals foran older version of CRT monitors through a DVI to VGA adaptor. The DVI-I connector is comprised of more pins in comparison to a DVI-D connector. The DVI-I connectors contain more pins because some of the pins are meant for sending digital signals and the rest send analog signals whereas since the DVI-D sends only the digital signals, it does not contain the pins needed for sending analog signals.

The DVIDIA graphics cards that carry the DVI-I connector are completely compatible with flat LCD monitors who exclusively have DVI-D cables. In this context, the DVI-D reads only the digital signal from the DVI-I connector in the card ignoring the analog signal. If in the case you have an NVIDIA graphics card which has two out-put connectors such as VGA as well as DVI, you may not necessarily expect that it would support dual monitors at a time. Some NVIDIA cards feature both the VGA connector as well as DVI connector. However, these types of dual NVIDIA will support only one type of signal as well as a display at a time. The reason behind providing these types of dual connect setting is to allow you analog or digital connection to your PC whenever and whichever is compatible for you.
