What is the use of dvi interface?

The DVI interface is a technology used for high-speed transmission of digital signals. The protocol of the DVI interface causes the brightness and color signals of the pixels to be sent from the signal source to the display device in binary form.

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

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

Relative to pixel data sent in analog mode, it will be affected by adjacent pixel data, electromagnetic noise and other analog lossy effects. In this method, each pixel in the output register directly corresponds to each pixel on the display. pixels. This ensures basic picture quality.

DVI is a high-definition interface, but it does not carry audio. In other words, the DVI video cable only transmits picture graphics signals, but not audio signals.

Extended information

In addition to the digital signal pins specified by the DVI standard, the DVI connector can also contain traditional analog signals (VGA) pin position, this design is to maintain the versatility of DVI so that different types of displays can share the same connection line.

With different functions, 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 are available; single link or dual link)

In addition, there are implementations The connector of the two sets of DVI circuits is called DVI-DL (dual link) to emphasize the transmission capability.
