DVI (Digital Video Interface) is an interface for digital and analogue video data transmission. It is considered the digital successor to the S-VGA standard and has established itself over the years, along with HDMI, as a means of communication between computers and monitors.
It is important to know that HDMI can transmit both image and sound, whereas the DVI standard only transmits pure image information.
The user may encounter several types of output:
this output requires only the possibility of analogue transmission
- DVI-I (SingleLink)
This output is available in two versions: Single Link and Dual Link. The first type is very popular and widely used. An additional letter I indicates that it is an integrated connector
- DVI-I (DualLink)
A dual link connector with the letter I transmits an analogue signal. It has two full digital channels. This allows the user to achieve much better picture quality and expand their capabilities
- DVI-D (SingleLin)
This has no analogue channel. There is only a digital transmission through this connector. As with the previous editions, there is a single and a double link. Single links restrict the user somewhat. The resolution must not exceed 1920 x 1200 (at 60 Hz). With this variant, there is only one digital channel. The user will not be able to connect an analogue monitor and enjoy the technology called nVidia 3D Vision
- DVI-D (Dual Link)
Dual Link allows you to see 3D on the monitor, which expands the user's capabilities. There are two digital channels
