When setting up a display for presentations, which connection type is often preferred for providing both audio and video signals?

HDMI, or High-Definition Multimedia Interface, is often preferred for presentations because it is capable of transmitting both high-quality video and audio signals over a single cable. This dual capability simplifies setup, reduces cable clutter, and ensures that both the video content and sound are synchronized effectively, which is crucial during presentations.

In contrast, VGA and DVI primarily handle video signals and do not include audio transmission. This would necessitate additional audio cables, complicating the setup process. RCA connections, while they can carry audio and video, are more commonly associated with older equipment and provide lower quality compared to HDMI, making them less ideal for modern presentations, where clarity and convenience are priorities.
