There are three main types of display data cable: HDMI cable, VGA cable and DVI cable. Now we basically choose the display with HDMI interface (HD interface), so it is very important to choose a good HDMI HD cable.
1. HD line - HDMI interface version
To select an HDMI HD cable, you must first check the version number of the HDMI connector. Depending on the HDMI interface version, the bandwidth and supported technologies are also different. At present, HDMI HD cable and HDMI interface can be divided into more than 1.3 to 2.0 versions. The higher version is compatible with the lower version. Therefore, when selecting HDMI HD cable, it should match the HDMI interface. At least it cannot be lower than the interface version. When it is lower than the interface version, the impact of HD cannot be transmitted. On the contrary, if it is higher than the interface version, it can be used, but you have to spend more.
2. HD line - HDMI line certification
HDMI cable is standard, so if there is a certification mark, the quality will not be a problem. There are currently two types of authentication. One is HDMI authentication and the other is Simplay authentication. Only one of these two certifications is required. Of course, it is better to have both certifications.
3. HD line - HDMI line connector
The HDMI cable connector generally has two types: gold-plated and gold-plated. The gold-plated connector has good corrosion resistance, conductivity and high temperature resistance. Therefore, generally speaking, the wire with gold-plated connector is better. The gold-plated connector on the market is 24K gold-plated, with high brightness, which is easy to distinguish. But the failure of gilding does not mean that it is not bad. Because it is the PIN pin in the HDMI connector that functions during use, this is the main connection point.
This pin is mainly made of tin bronze. The pin is first plated with nickel, and then plated. So look carefully at the HDMI wire, and the pin will have three layers.
4. HD line - HDMI line process
The internal core of HDMI HD line is very important. At present, copper core should be used. The transmission capacity and quality of copper core are very good. It can prevent the signal from being disturbed. At the same time, too much loss will not occur during signal transmission. The other internal core is made of alloy and iron. Of course, this is worse. To determine the difference, it should be taken apart. There may not be many people who buy the line and take it down. So, Xiaobian introduces a relatively simple method, which can bend the HDMI HD line many times. The soft core is copper core, and the hard core is alloy and iron core, but pay attention not to bend too hard, and the alloy and iron core is easy to break.
Advantages of HDMI
1. Good quality. The digital interface has no module conversion loss and provides better video quality. This is especially noticeable at high resolution (e.g. 1080p or 4K).
2. Ease of use: Single-line integrated video signal and multi-channel audio signal are more practical than in the past when multiple lines need to be connected.
3. Intelligent: HDMI supports two-way communication between video source and playback device, and provides new functions such as automatic configuration and click-to-play.
