The difference between DisplayPort and HDMI, HDMI is the first to be developed for CRT, whether it is HDMI or its twin brother UDI (substantially remove the HDMI audio transmission function), both inherit the core technology of DVI TMDS, from the essence It is still an extension of DVI. The video content of DVI, HDMI and UDI are transmitted in an instant and dedicated way. This ensures that the video traffic will not be blocked when it is large. DisplayPort is developed for LCD monitors at the beginning, using Micro-Packet Architecture. Transmission architecture, video content is transmitted in a packet, which is significantly different from video transmission technologies such as DVI and HDMI. In other words, the emergence of HDMI replaced the analog model video, and the emergence of DisplayPort replaced the DVI and VGA interfaces.
The two are essentially different in the interface type. Secondly, HDMI can transmit audio signals and even network signals at the same time, and the DP interface only transmits video signals.
Due to the limited bandwidth, HDMI can only transmit up to 30 frames per unit time, and DP does not have this limitation. Therefore, at high resolution (3840*2160 or higher), the DP interface is better, at 1080P resolution. No difference. So DP (DisplayPort) is more HD than HDMI.
The full name of HDMI in English is High Definition Multimedia Interface, which is a high-definition multimedia interface. It is an all-digital video/sound transmission interface that can transmit uncompressed audio and video signals. HDMI provides all compatible devices. Such as DVD player, personal computer, TV game, integrated amplifier, digital audio and TV
-- A common data connection pipe, HDMI can transmit audio and video signals at the same time. Since the audio and video signals use the same cable, the system installation is greatly simplified.

The organization that develops the DisplayPort interface standard is VESA (Video Electronics Standards Organization). The earliest version was May 2006, and VESA released the Displayport 1.0 standard. Two advantages of DisplayPort: First, DisplayPort
At the protocol layer, DisplayPort uses MPA (Micro-Packet Architecture); second, it is a problem with portable devices such as notebooks. Using the DisplayPort interface greatly simplifies the wiring complexity.
