The difference and relationship between MiniDP and HDMI
HD output revolution pioneer: HDMI interface HDMI high-definition multimedia interface is a digital video / audio interface technology, is a dedicated digital interface for image transmission, which can transmit audio and video signals at the same time, the highest data transmission speed is 5Gbps, while There is no need to perform digital/analog or analog/digital conversion before signal transmission. HDMI can be paired with Wideband Digital Content Protection (HDCP) to prevent illegal copying.
The HDMI interface not only satisfies 1080P resolution, but also supports advanced audio formats such as Dolby TrueHD and DTS-HD Master Audio. At the same time, HDMI supports EDID and DDC2B, so HDMI devices have "plug and play" features, signal sources. “Negotiation” is automatically performed with the display device to automatically select the most appropriate video/audio format. Compared with DVI, the HDMI interface is smaller in size. The cable length of DVI cannot exceed 8 meters, otherwise it will affect the picture quality, and HDMI can transmit up to 15 meters. As long as one HDMI cable can replace up to 13 analog transmission lines, it can effectively solve the problem of messy connection behind the home entertainment system. Unfortunately, the use of the HDMI interface requires payment of a certain technical agreement license fee.
Challenge the rising star of HDMI: DP interface DVI and HDMI are transmitted by converting the signal into TMDS to minimize the transmission of differential signals. However, in the notebook field, it has long been the world of LVDS (Low-Voltage DifferenTIal Signaling). The introduction of the DisplayPort interface is a perfect solution to this problem. DisplayPort is now widely supported by the industry, mainly due to the two advantages of DisplayPort: First, the advantages of DisplayPort at the protocol layer, DisplayPort uses MPA (Micro-Packet Architecture); second, is notebooks, etc. The problem with portable devices. The use of the DisplayPort interface greatly simplifies the wiring complexity.
Regarding the difference between DisplayPort and HDMI, we know that HDMI is the first specification for CRT, and inherits the core technology of DVI, TMDS, which is still an extension of DVI in essence. The video content of DVI, HDMI and UDI are transmitted in an instant and dedicated way, which ensures that the video traffic will not be blocked when it is large. DisplayPort was originally developed for LCD monitors. It uses the "Micro-Packet Architecture" transmission architecture, and video content is transmitted in packets. This is significantly different from video transmission technologies such as DVI and HDMI. In other words, the emergence of HDMI replaced the analog signal video, and the emergence of DisplayPort replaced the DVI and VGA interfaces.
Good or bad relationship between DP and HDMI:
The DP interface is better. The main reason is that HDMI can only transmit up to 30 frames per unit time due to bandwidth limitation. DP does not have this limitation. Therefore, at high resolution (3840*2160 or higher), the DP interface is better. There is no difference in the resolution of 1080P.
The difference between HDMI and DP is the number of frames of images transmitted per unit time. HDMI can only transmit 30 frames, and DP is unlimited.
High-definition multimedia interface (English: High DefiniTIon MulTImedia Interface, HDMI) is a digital video/audio interface technology. It is a dedicated digital interface suitable for image transmission. It can transmit audio and video signals at the same time. The maximum data transmission speed is 4.5. GB/s.
The Dp interface, which is the DisplayPort interface, is a transmission interface for high-definition audio and video streams. The longest external distance can reach 15 meters, although this distance is inferior to HDMI, but the specifications of the connector and wiring have been prepared for future upgrades, even if the future DisplayPort adopts the new 2X rate standard (21.6Gbps), the connector And the wiring does not have to be redesigned. In addition to the connection between the device and the device, DisplayPort can also be used as an interface inside the device, or even a data interface between the chip and the chip.
The difference between the MINI DP interface and the Thunderbolt interface is as follows:
1. The main difference between the Mini DP interface and the ThunderBolt interface is that ThunderBolt has a data transfer function (PCI), while the MINI DP does not have the function of transmitting data.

2, ThunderBolt is a composite interface, it can be understood that it can provide PCI-E to external devices Mini-DP only supports display; ThunderBolt is now available on most platforms in the form of Mini-Displayport interface.
