What is the primary feature of DVI-I connectors?

The primary feature of DVI-I connectors is that they are designed to accommodate both analog and digital signals, which is the reason why they include extra pins. DVI-I stands for Digital Visual Interface - Integrated, and this connector type can seamlessly connect devices that use either digital signals (like DVI-D) or analog signals (like DVI-A).

This versatility allows DVI-I connections to support a wider range of display technologies, making it a more flexible option for varying setups, including traditional VGA connections and modern digital displays. The additional pins facilitate the analog signal path, making it an important feature for situations where both types of signal outputs are needed, such as in older displays alongside modern digital systems.

In contrast, other types of DVI connectors do not offer this dual functionality; for example, DVI-D is designed exclusively for digital signals. Therefore, DVI-I's capability to support both analog and digital makes it unique among connector types in the DVI family.
