What are DVI Cables?
DVI cables are 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. The traditional Video Graphics Array (VGA) interface was designed for use with analog CRT (cathode ray tube) monitors. It converts digital signals received from the graphics card into analog signals which it sends to the monitor. This conversion to analog creates minute distortions in the integrity of the signal. While necessary for CRT monitors, flat panel displays are themselves digital. With a DVI interface on the video or graphics card, pure digital output can be achieved using DVI cables, resulting in a sharper picture. There are several types of DVI cables or connectors. 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.

DVI cables are used with high-end graphics cards to utilize the newer Digital Visual Interface, (sometimes called Digital Video Interface), in order to maximize the benefit of flat panel digital displays. The traditional Video Graphics Array (VGA) interface was designed for use with analog CRT (cathode ray tube) monitors, converting the digital graphics card signal to analog. This conversion to analog creates minute distortions in the integrity of the signal. While necessary for CRT monitors, flat panel displays are themselves digital. With a DVI interface on the video or graphics card, pure digital output can be achieved using DVI cables, resulting in the sharpest possible picture. There are several types of DVI cables or connectors. Some transfer both analog and digital signals to accommodate intermixed components while the market transitions from the VGA standard (and CRT monitors) to digital monitors. Though CRT monitors will no doubt be around for a long time, when upgrading a gra
