Which characteristics are correct for DVI-D connectors?

1. They can transmit both digital and analog signals.

2. They only transmit digital video signals.

3. They have a capacity for higher resolutions than HDMI.

4. They require additional power from the motherboard.

The correct answer is: They only transmit digital video signals.

DVI-D connectors are specifically designed to transmit digital video signals only. Unlike DVI-I connectors, which can transmit both digital and analog signals, DVI-D is purely a digital format, meaning it is optimized for sending video data in a digital format without any analog capability. This characteristic makes DVI-D well-suited for high-quality digital displays, enabling clearer and more accurate image reproduction compared to analog signals. While it is true that DVI can support high resolutions, HDMI typically has broader capabilities in terms of features beyond just video signal transmission, such as audio transmission and support for various digital formats. Therefore, the statement regarding the capacity for higher resolutions than HDMI doesn't hold for DVI-D. Additionally, DVI-D does not require additional power from the motherboard, as it is designed to function with the power supplied through the connection itself. Thus, the correct understanding of DVI-D's purpose and functionality revolves around its exclusive focus on digital video transmission.
