In 2006, the Video Electronics Standards Association (VESA) designed a new display interface to compete with HDMI: the DisplayPort. Since then DisplayPort has become more and more popular in the computer world. Let’s take a look at the evolution of DisplayPort over the years.
DisplayPort is the first display interface which applies packetized data transmission, like Ethernet, USB and PCIe. Unlike legacy standards that transmit a clock signal over 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. This allows higher resolution using fewer pins in addition to make DisplayPort extensible, meaning that additional features can be added over time without significant changes to the physical interface.
