What is the difference between the DP interface and the HDMI

- Jun 29, 2018 -

DP has higher resolution than HDMI and belongs to professional device output / input interface.

The difference between DisplayPort and HDMI is that HDMI is the first set of specifications for CRT. Both HDMI or its "twin brother" UDI (essentially the audio transmission of the HDMI), both inherit the core technology TMDS of DVI, which is essentially an extension of DVI. The video content of DVI, HDMI and UDI is transmitted in instant and special line mode. This ensures that the video traffic is not blocked when the traffic is large and the DisplayPort is developed at the beginning of the video. The "Micro-Packet Architecture (micro packet architecture)" transmission architecture is used for the video content to be transmitted in a packet mode. This is the same as D. Video transmission technologies such as VI and HDMI have obvious differences. That is to say, the emergence of HDMI has replaced analog models, while the emergence of DisplayPort has replaced DVI and VGA interfaces.

There are essential differences between the two types of interfaces. Secondly, HDMI can transmit audio signals and even network signals at the same time. The DP interface only transmits video signals.
