As the types of digital products are becoming more and more, the types of data cables are becoming more diverse. Android lines, Apple lines, Type-C lines, HMDI cables, Thunderbolt 3, the data cable interfaces in life are endless, and most of the small partners cannot distinguish between them.
Many times, everyone is holding the data cable to the interface, as long as they can be inserted, everything is good. When buying electronic accessories, the priority of the data cable is not high, and usually buy one casually.
In fact, the importance of data cables is seriously underestimated.
Data cables of different interfaces and different materials, their functions, data transmission speed, charging speed, and audio and video data transmission capacity are very large.
On smartphones, the data cable interface is relatively simple, mainly divided into Micro USB interfaces (commonly known as Android line interfaces), USB Type C interface, Lightning interface (commonly known as Apple wire interface). On PC and laptop, the data cable interface is much more complicated. USB interface, lightning interface, HDMI interface, VGA interface, DP interface, each interface corresponds to different data cables.
VGA interface, old and strong
Every small partner who has assembled desktop computers will not be unfamiliar with the VGA interface. 3 rows of 15 needles, one screw on each side, connecting the computer host while connecting the display screen. Ten years ago, when Xiao Hei had just touched the computer, he would check the VGA interface as soon as possible when he encountered the black screen to see if the data connection was loosened.
In the CRT display era, analog signal is accepted. The VGA interface using analog protocol is almost necessary for each computer. Today, the VGA interface is still active in a desktop computer. The friends check the computer host and the display. Maybe it is the blue VGA interface.

As an old -fashioned interface, the advantage of VGA is that it is strong and cheap, and is especially suitable as an entry -level product. However, due to the problems such as cable and signal interference, VGA data transmission efficiency is not high, and generally can only reach 1080P resolution. When installing the machine, if you buy high -performance graphics cards and 2K, 4K display, do not match the VGA data cable, otherwise you will find problems such as font deficiency and image drag.
HDMI interface, audio and video transmission at the same time
The HDMI interface appeared 15 years later than VGA and was born in December 2002. HDMI can send video and audio signals at the same time, simplifying the computer connection method.
In the early years, the highest data transmission speed of the HDMI interface was 5Gbps, which could support 2K, 1080P, and 720P full HD format video output. Today, HDMI has developed to the HDMI 2.1 standard to support 4K 120Hz and 8K 60Hz, support high dynamic range imaging (HDR), can be optimized for scenes or frames, and is compatible with HDMI 2.0 and HDMI 1.4.
Dynamic HDR, including Dolby Vision and HDR10+, can control the color and details of each frame through different metadata, thereby maintaining a good display effect. The so -called frame number optimization is actually a variable refresh rate. It is similar to the Apple iPhone 13 LTPO technology, which can reduce or eliminate the delay, stuttering and tearing of the screen to make the game more complete. In addition, HDMI 2.1 also supports ALLM automatic low latency mode. Smart TVs can achieve a stuck and interrupt viewing experience.
Seeing this, the little friends may understand why the PS5 connect to the TV is delayed, and the main screen of the 3390 graphics card display effect is average. This is a pot where the data line is not selected. In the HDMI 2.1 data cable selection, there are entry -level Green Union data cables, and there are also fever -level Kaobol data cables.
Taking the Kaobol 8K optical fiber HDMI five -generation data cable used as an example, the interface copper shell is plated. Compared with the traditional VGA data cable and HDMI 2.0 data cable, the experience is different.

DP interface, niche good product
DP interface is DisplayPort. Like the HDMI interface, it is a high -definition digital display interface standard. It supports audio and video transmission at the same time. It can connect to computers and monitors and other devices.
Judging from the birth time, the DP interface was launched in 2006, which is a relatively late technology. Compared with the HDMI interface, the DP interface has a higher bandwidth and refresh rate. The first DP1.2 interface, with a maximum transmission speed of 21.6Gbps, supports 1080P 240Hz, 2K 165Hz, 4K 75Hz, 5K 30Hz, which is much higher than the HDMI interface in the same period.
With the advancement of technology, the DP 2.0 interface bandwidth is as high as 77.4Gbps, which is 61%higher than HDMI 2.1. It can achieve up to two 8K 120Hz video output, which is simply a must -have data cable for audio enthusiasts.
The performance of the top DP line is unparalleled. The effect of the top DP1.4 data cable is also very stunning. 8K 60Hz, 4K 144Hz, can basically meet the needs of game enthusiasts. Xiao Hei used the Kaobol DP line 1.4 to connect to the 4K display,
Perfectly exerts the exquisite display effect of the screen.

The biggest disadvantage of the DP interface is not the product itself, but the degree of popularity.
In the world of HDMI interfaces, many display screens and TVs do not support DP interfaces. There are far more devices that support HDMI interface than DP interfaces. Therefore, when buying the DP data cable, the friends must have confirmed whether their device contains the DP interface.
