This article mainly introduces the role of dvi interface, the article is very detailed, has a certain reference value, interested friends must read it!

The dvi interface is a technology for high-speed transmission of digital signals. The protocol of the DVI interface makes the brightness and color signals of pixels from the signal source to the display device in a binary manner.

DVI interface is a technology used for high-speed transmission of digital signals.

The protocol of the DVI interface enables the brightness and color signals of pixels to be sent to the display device in a binary manner from the signal source (such as the graphics card).

The pixel data transmitted relative to the analog mode will be affected by adjacent pixel data, electromagnetic noise and other analog losses. in this method, each pixel in the output register corresponds directly to each pixel on the display side. So that the picture quality has a basic guarantee.

DVI is a high-definition interface, but does not have audio, that is, DVI video wiring only transmits picture graphics signals, but not audio signals.

Extended data

In addition to the digital signal pins specified in the DVI standard, the DVI connector can also contain traditional analog signal (VGA) pins, which is designed to maintain the versatility of the DVI so that different forms of displays can share the same cable.

Depending on the functionality implemented, DVI connectors are divided into three types:

1. DVI-D (Digital digital signal; single link or dual link)

2. DVI-A (Analog analog signal)

3. DVI-I (Integrated hybrid; both digital and analog signals; single link or dual link)

In addition, the connectors that implement the second set of DVI circuits are called DVI-DL (dual link) to emphasize transmission capacity.
