An HDMI dongle is a compact device that plugs directly into the HDMI port of a display, such as a TV or monitor, and adds smart functionality or specific connectivity features. Commonly used to stream media, share content, or extend connectivity, HDMI dongles are popular for their portability and ease of use.

- Plug and Play: These devices are typically plug-and-play, requiring minimal setup—just connect the dongle to an HDMI port and power source (often via USB), and you're ready to go.
- Portability: Their small size makes HDMI dongles ideal for travel, allowing users to bring smart functionality to hotel TVs or other displays while on the go.
