For example, the number of pins, the arrangement of the pins and the location of the pins vary. So, if you know what is a DVI connector type, you can quickly tell which type of DVI port it is and what its main purpose is.

    The type of DVI connector

    DVI connectors are divided into three main categories: DVI-Interated, DVI-Digital, and DVI-Analog. the first one is able to support both digital and analog signals. For instance, this type of connector can be used to transmit video from an old computer to a display screen. The second type can only transmit digital signals. Currently, it is usually used for outdoor LED signs, HDTV and other high-end equipment. And DVI-Analog is usually not connected to the display device. It only has the role of transmitting analog signals.

    In addition to the different types of signals transmitted, these three types also differ in terms of the equipment they are suitable for, the speed at which the data is transmitted, the number of pins, and the arrangement of the pins.

    What is the difference between DVI and HDMI

    The biggest difference between DVI and HDMI ports is that DVI ports can’t transmit audio, but HDMI ports can.

    Aside from the appearance, VGA is more preferred by the industry because it can only transmit analog signals while DVI can transmit both analog and digital signals. This is because if you want to transmit digital signals via VGA, you need to go through the tedious process of converting digital signals into analog signals and then into digital signals.

    In contrast, DVI is capable of direct transmission, saving users the time of converting signals. In addition, the resolution of the content they support is different, DVI interface can support higher resolution transmission, to provide users with clearer video quality. Therefore, you need to pick the most suitable one among DVI and VGA according to the actual usage requirements.


    In the era of rapid development of real technology, we use electronic display devices in our daily life. As people demand for the display effect and the way to transmit the content of the display device, the style and function of the connector are also updated and upgraded. I hope this article can let you grasp what is a DVI connector look like, function, advantages and other information. It can help you to choose the right connector when transferring the content to the display device to ensure the fastest speed without compromising the quality of the content transferred to the device for playback and display.
