What is the DP interface?

What is the DP interface?

With the several great revolutions of computer technology, the high image quality is what most people pursue, so the importance of the graphics card is unknown. Of course, in addition to the support of the graphics card, the display should also be supported. However, the interface types of different displays are different. It can be roughly divided into 4 types: DP/ HDMI/ DVI/VGA. Here I am going to share information about DP.

The DP is short for the Display-Port interface, which is a display interface issued by the Video Electronics Standards Association (VESA). As the successor of DVI, Display-Port will add support for HD audio signal transmission while transmitting video signals, and support higher resolution and refresh rate. It can support single channel, one-way and four line connections, with a data transmission rate of 10.8gbps, which is sufficient to transmit uncompressed video and related audio. It also supports 1Mbps bidirectional auxiliary channels for equipment control. In addition, it also supports 8-bit and 10 bit colors. In data transmission, Display-Port uses the "micro packaged" format. VESA also said that Display-Port is highly calculable and can continuously add more new content in the future.

Analysis of application characteristics of DP interface

AMD multi-screen splicing technology must have Display-Port interface. In the hd5000 Series graphics card just released recently, AMD supports the latest multi-screen splicing display technology released by AMD. Take three screen splicing as an example. AMD's hd5000 Series graphics card is designed with DisplayPort interface. The user needs to connect with the display device supporting this interface through the DisplayPort data line to become the main display of three screen splicing display, and must be directly connected with the DisplayPort interface without any form of conversion. Therefore, for display fever users, their demand for liquid crystal displays capable of supporting DisplayPort interfaces gradually increases.

In terms of performance, DisplayPort 1.1 can support a maximum transmission bandwidth of 10.8gb/s, while the latest HDMI 1.3 standard can only support a bandwidth of 10.2g/s; In addition, DisplayPort can support WQXGA + (2560×1600)、QXGA(2048×1536) equal resolution and color depth of 30 / 36bit (10 / 12bit per primary color), 1920×1200 resolution color supports 120 / 24bit, and the ultra-high bandwidth and resolution are fully enough to adapt to the display.

DisplayPort has won the support of industry giants such as AMD, Intel, NVIDIA, Dell, HP, Lenovo, Philips and Samsung. Moreover, it is free to use, unlike HDMI, which requires a high authorization fee. AMD's Roadmap shows that the company began to support DisplayPort in 2014 to replace HDMI. Although there are many kinds of devices that support HDMI interface, for these devices, HDMI interface is only a more convenient connection mode, and has no other applicability. As for DisplayPort , due to the support of multi-screen splicing technology developed by AMD on hd5000 Series graphics cards and the need for DisplayPort to transmit the signal of the main display, the powerful interface is still very attractive to enthusiasts.

In the above, we have introduced in detail the relevant information about what the DP interface is. Through the above, we can roughly understand the definition and some characteristics of the DP interface. The advantage of the DP interface over the other two interfaces is that it supports higher resolution and refresh rate. More powerful. However, it has only emerged in recent years. Old machines may not be equipped with this interface. However, there is an adapter cable on the market, so if the configuration of the computer supports it, it will not affect the normal use. However, if the adapter cable is used, the effect may not be very good.

If your computer do not have DP port but need to connect to DP display, another solution is to use a docking station with DP port or DP video converter.

Here are 2 sample pictures of these 2 products. You can click and to learn more about them.DP docking stations
