DisplayPort is a digital video interface standard formulated by VESA (Video Electronics Standards Association). It was originally designed to replace older analog video interface standards such as DVI and VGA to meet the needs of high resolution, high refresh rate, and multiple displays. DisplayPort can transmit high-definition video, audio and data signals, and also supports HDCP (High-bandwidth Digital Content Protection) copyright protection technology. Advantages of DisplayPort:
1. High bandwidth: DisplayPort can provide up to 32.4Gbps bandwidth, which means it can support higher resolution, higher refresh rate and deeper color depth. For example, DisplayPort 1.4 can support 8K resolution (7680x4320) and 120Hz refresh rate.
2. Multi-monitor support: DisplayPort supports multi-monitor connection, you can connect multiple monitors through one DisplayPort interface, or connect multiple monitors through daisy-chain (serial connection).
3. Flexibility: DisplayPort supports multiple connection methods, including standard DisplayPort interface, Mini DisplayPort interface, USB Type-C interface, etc. These interfaces can be converted to each other, making DisplayPort compatible with various devices.
4. Reliability: DisplayPort adopts differential signal transmission technology, which can effectively resist electromagnetic interference and signal attenuation, and ensure the stability and reliability of the signal.
5. Support multiple applications: In addition to transmitting video and audio signals, DisplayPort can also transmit data signals, support USB, Ethernet and other protocols, and can realize multiple applications, such as data transmission, network connection, etc.
DisplayPort is a high-performance, high-reliability digital video interface standard, which can meet the needs of various high-definition video and audio transmission, and also has flexibility and scalability to support a variety of applications. It is widely used in high-end monitors, graphics cards, notebook computers and other equipment.
