This allows for higher resolution using fewer pins. It permits the use of internal and external display connections, and unlike legacy standards that transmit a clock signal with each output, the DisplayPort protocol is based on small data packets known as micro packets, which can embed the clock signal within the data stream. The interface is backward compatible with other interfaces, such as HDMI and DVI, through the use of either active or passive adapters.ĭisplayPort is the first display interface to rely on packetized data transmission, a form of digital communication found in technologies such as Ethernet, USB, and PCI Express. ĭisplayPort was designed to replace VGA, FPD-Link, and Digital Visual Interface (DVI).
The interface is primarily used to connect a video source to a display device such as a computer monitor, and it can also carry audio, USB, and other forms of data.
