DisplayPort, often abbreviated as DP, is a digital display interface standard developed by the Video Electronics Standards Association (VESI). It is primarily used to connect a video source, such as a graphics card or computer, to a display device, like a monitor or television. DisplayPort is designed to be a more advanced and flexible alternative to older standards like VGA and DVI.

One of the key advantages of DisplayPort is its ability to transmit both high-definition video and audio signals over a single cable. It supports high resolutions and refresh rates, making it suitable for demanding applications like gaming and professional video editing. The standard also allows for multi-stream transport (MST), enabling multiple independent displays to be connected to a single DisplayPort output.

DisplayPort utilizes a packet-based data transmission method, which allows for efficient data transfer and future scalability. It has undergone several revisions, with each new version introducing improvements in bandwidth, features, and capabilities. Common versions include DisplayPort 1.2, 1.4, and the latest DisplayPort 2.0, which offers significantly higher bandwidth for even higher resolutions and refresh rates.

While similar in some aspects to HDMI, DisplayPort is generally favored in the PC and professional monitor markets due to its openness and advanced features like MST. It is often found on graphics cards and high-end monitors.
