DVI, known as Digital Visual Interface, is a Digital Display Working Group DDWG(Digital Display Working Group) launched in 1999 by Silicon Image, Intel(Intel), Compaq(Compaq), IBM, HP(HP), NEC, Fujitsu(Fujitsu) and other companies. Its appearance is a 24-pin connector. Display device adopts DVI interface has basically has the following two advantages: one, the high speed: DVI is digital signal transmission, do not need any conversion, digital image information will be transmitted directly to the display device, thus reducing the digital and analog to digital conversion process trival, greatly save the time, so it is faster, effectively eliminate the phenomenon of ghosting, DVI and used for data transmission, signal attenuation, no colour more pure, more vivid.
Second, the picture is clear: the computer inside is A binary digital signal transmission, using A VGA interface LCD connection requires the first signal through D/A in the graphics card, digital/analog converter into R, G, B color signal and line, A synchronous signal, the signal through the analog signal transmitted to the LCD inside also need corresponding A/D (analog/digital) converter will once again into A digital signal to analog signal in the image is shown on the LCD. In the above D/A, A/D conversion and signal transmission process, signal loss and interference will inevitably occur, resulting in image distortion and even display error. However, DVI interface does not need to carry out these conversions to avoid signal loss and greatly improve the clarity and detail expression of the image.
