Which characteristic is associated with the Mini-HDMI connector?

The Mini-HDMI connector is specifically designed to support high-definition video and audio transmission. This capability allows devices to transmit high-quality multimedia content, making it particularly suitable for connecting devices like cameras and small laptops to larger screens such as TVs or projectors.

In contrast, the other options do not accurately represent the primary function of the Mini-HDMI connector. For instance, the connector is not used for power connections, nor is it limited strictly to audio output. Additionally, it does not operate solely on low-definition video formats; rather, its design purpose centers around high-definition capabilities, highlighting its versatility and effectiveness in modern multimedia applications.
