What are DVI cables?

The

DVI cables are used with graphics cards with DVI enabled to use the digital visual interface (sometimes called digital video interface ) to maximize the advantage of digital flat panel displays.

The interface of the traditional video field video (VGA) was designed for use with analog CRT monitors (cathode ray tubes). It converts digital signals received from the graphics card to analog signals that sends it to the monitor. This transformation into analog creates a minute of signal integrity. Although the CRT monitors are necessary, the displays of flat panels are digital themselves. With the DVI interface on a video or graphics card, you can achieve a clean digital output using DVI cables, resulting in a sharper image.

There are several types of cables or DVI connectors. Some transmit both analog and digital signals to suit promoted components because this digital interface function as a bridge between the VGA market crossingand CRT monitor on digital monitors. The main types of DVI cables are:

DVI-D (digital, for use with digital displays): These cables connect the DVI-graphics card to the digital display. They carry digital digital signals, eliminate analog conversion and cannot accommodate CRT displays.

DVI-A (analog, for use with analog displays): These DVI cables are running from the DVI graphics card with an analog CRT display, converting digital-analog . Although some cleanliness is lost when converted from digital to analog, the use of the DVI card and the DVI-A cable with the CRT monitor provides excellent performance for using the VGA interface.

DVI-I (integrated, for use with both displays): These cables act as digital to digital or analog analog and therefore it istheir designation as "integrated". They do not translate digital-to-analog or analog-digital. These DVI cables can be used to connect the DVI graphics card to the digital display or the DVI VGI card interface to the analog display.

Double -connected cables have the ability to provide greater speed, greater signal quality and extremely high resolution using another "pipe" when the first line was maximized. This is particularly important for very large screens that require high resolution more than 2.3 million pixels. For comparison, most 17 inches to 19 -inch digital displays have a native resolution of about 1.3 million pixels.

When buying DVI cables, make sure that the cables you are buying are right for your components. It may also be interesting to note that the DVI standard has been replaced by Unified Display Interface (UDI) and DisplayPort Standards.
