The Digital Video Interface (DVI) is a video interface standard covering the transmission of video between a source device (such as a personal computer) and a display device. The DVI standard has achieved widespread acceptance in the PC industry, both in desktop PCs and monitors. DVI digital cable is used with DVI-enabled graphics cards to utilize the Digital Visual Interface (sometimes called Digital Video Interface), in order to maximize the benefit of flat panel digital displays.
There are several types of DVI digital cable or connector. Some transfer both analog and digital signals to accommodate intermixed components, as this digital interface acted as a bridge between the market transition from VGA and CRT monitors to digital monitors. When purchasing DVI cables, check with a knowledgeable salesperson to make sure the cables you are buying are right for your components.
In order to choose the best digital video interface (DVI) cable, you will need to consider the components you are working with. The other main factor to consider is if a cable is dual- or single-link, since a dual-link DVI cable can transmit a higher resolution image. You will also want to choose a DVI cable that is an appropriate length, as some devices cannot transmit a signal over cables that are longer than about 16 feet (5 meters).
