What do DisplayPorts typically output?

DisplayPorts are designed as versatile interfaces that are capable of transmitting both video and audio signals. This dual functionality allows a single cable connection to carry high-definition video to a monitor while simultaneously sending audio to speakers, making it a popular choice for connecting computers to displays. This capability facilitates a cleaner setup with fewer cables, as users can enjoy audio and visual output seamlessly through one interface.

The other options do not capture this dual-output feature of DisplayPorts. Video only or audio only would limit functionality, making them less effective for comprehensive multimedia applications. Data transfer typically refers to different interfaces like USB, which focuses on transmitting data rather than audio or video. Hence, the primary feature of DisplayPorts that allows for both media types is why this answer is the most appropriate.
