In addition to the power cable, the other cable is the display data cable. Currently, there are three main types: HDMI cable, VGA cable and DVI cable. These days, you're basically choosing a monitor with an HDMI port, so it's important to get a good HDMI cable.

So do you know how to choose a good HDMI cable? The following Xiaobian to introduce several methods, mainly the following 5 aspects to choose, let's have a look.

01 HDMI port version

To select an HDMI HD cable, first check the version number of the HDMI port. The bandwidth and supported technologies vary depending on the version of the HDMI port. Currently, HDMI cables and HDMI ports are available in versions 1.3 to 2.0 and above, with higher versions compatible with lower versions. Therefore, it is best to choose an HDMI HD cable that matches the HDMI interface, at least not less than the interface version. If the version is earlier than the interface version, HD effects cannot be transmitted. Conversely, if it is higher than the interface version, you will spend more money, although it can be used.

02 Authentication of HDMI HD cable

HDMI HD cables come with standards, so if there is a certification mark, there are usually no quality issues. Currently, there are two kinds of certification, one is HDMI certification and the other is Sinplay certification. Preferably, of course, both certificates are available.

03 Connector for HDMI HD cable

The connector of HDMI HD cable is generally gold-plated and non-gold-plated. The gold-plated connector will have better corrosion resistance, electrical conductivity and high temperature resistance. So normally, there is a gold-plated joint line will be better and more durable, many gold-plated joints on the market with 24K gold, relatively high brightness, it is easy to distinguish. But it is not so bad that it is not gold-plated, because in the process of use, it ultimately plays a role or the PIN pin inside the HDMI connector, which is the main connection point.

This PIN is mainly made of tin bronze. At the time of production, the PIN is first plated with nickel and then gold plated. Therefore, if the work is good HDMI HD cable, take a closer look at its PIN pin, you will find that it is three layers.

04 HDMI HD cable technology

The inner core of the HDMI HD cable is very important. At present, the best is copper core. Copper core transmission capacity and transmission quality is very good, can prevent signal interference. At the same time, the signal does not lose much in transmission. There is also an inner core made of alloy and iron, which is, of course, relatively poor. If you want to really tell it apart, you can only take it apart, but few people should buy a cable to remove it, so I'll show you an easy way. You can bend the HDMI cable and bend it multiple times. If it is soft, it is a copper core, if it is hard, it is an alloy and iron inner core, but be careful not to bend too much, or the alloy and iron inner core can easily break. 

Of course, there have been some developments in the inner core of HDMI HD cables, some of which use fiber directly as the inner core. There is no mention here of the benefits of using fiber optics. Today's broadband is basically fiber optic, so you should get the idea. Of course, fiber-core HDMI cables are very expensive. If funds allow, I recommend the use of fiber core HDMI HD cable, if you need longer HDMI HD cable, more should choose fiber core, ordinary users generally choose copper core.

05 Thickness of HDMI HD cable

Some HDMI HD cable very thick, some very thin, how to choose? Generally, for the same brand, the thicker the line, the better the transmission performance, and the more stable, but it is better to choose the brand line. Some miscellaneous lines add a lot of miscellaneous items to make the lines look thicker. Therefore, it is best to choose a brand when choosing an HDMI HD cable, such as HDERA HDMI HD cable. 

Thin HDMI HD cables will never work. When the cable is used for data transmission, the signal will be relatively poor. HDMI cable cable gauge (AWG). The larger the number, the smaller the cable diameter. Pay attention to this when buying, for example 20AWG will be better than 30AWG for the same brand.

The production cost of HDMI HD cable is relatively high, so usually the more expensive the better, but the premise is qualified, how to choose HDMI HD cable, I believe after reading the above content, we are very clear, the first version must be suitable, the second must be suitable for your use environment, and then must ensure the brand and quality of the cable. If the above conditions are met, it is a good HDMI cable.
