When using the high-definition playback platform or even the 4K high-definition playback platform, we can't avoid the situation of choosing and buying HDMI cable. At this time, some small partners will ask, how to choose HDMI cable to be professional?Next we will tell you from several aspects how to choose a good HDMI cable.
Step 1: Determine the HDMI interface version
HDMI interface is different, bandwidth and support technology are different, and HDMI cable is also divided into 1.3 to 2.0 versions in the market and HDMI interface, and is backward compatible, so HDMI cable should be compatible with HDMI interface version. , at least the wire version should be higher than the interface version.
If the optional wire version is lower than the interface, the HDMI2.0 interface is equipped with an HDMI1.4 cable, which is unable to transmit 4K@60hz video and video, but if you give the HDMI1.4 interface with an HDMI2.0 cable, There is no problem in use, just spend more money, because the high version of HDMI cable will certainly be slightly more expensive.
Step 2: Look at the wire with or without the certification mark
HDMI certification
Sinplay certification
Check whether the product packaging has HDMI or Simplay certification mark. Good wire will have two association certification marks at the same time, and the quality is more secure.
Step 3: Look at the wire connector
If the connector of the HDMI cable is a gold-plated connector, in addition to being more beautiful, it theoretically has better corrosion resistance, electrical conductivity and high temperature resistance, and is also easy to solder. Therefore, gold-plated joints are better than non-gold-plated joints. The common gold-plated joints on the market are 24K gold-plated and have high brightness. But it doesn't mean that the connector is gold-plated, and the pin is connected to the HDMI connector. Therefore, the HDMI cable connector is the most important part.
pin
The material of the pin is generally tin bronze, which has high elasticity, excellent wear resistance and corrosion resistance. Generally, the pin will be plated with nickel on tin bronze, and then it is easy to plate gold. Therefore, the pin of the HDMI cable with good workmanship can observe three layers.
Step 4: Look at the manufacturing materials and processes of the wire
There are several kinds of materials for the traditional HDMI wire core. Generally, the best copper is pure copper, or pure copper is plated with silver. Pure copper can guarantee the quality of signal transmission, reduce signal interference and signal loss, and use alloy and iron. As the inner core. How to tell? Of course, it is best to distinguish and see, and it is the most impossible. We can bend the wire properly. The copper wire is soft and flexible. Otherwise, it may not be copper wire. It is easy to break after repeated bending.
Fiber core
Now there are new changes in the core of HDMI cable. I believe many consumers have heard of HDMI cable with optical fiber as the core. The optical fiber HDMI cable uses optical fiber as the transmission material. Compared with the electrical signal propagation of the copper wire, the optical signal transmission can achieve faster speed, longer transmission and complete signal transmission.
In the past, the longer the transmission distance of the copper core HDMI cable, the faster the transmission signal is attenuated, and the optical fiber HDMI cable breaks through this limitation, and it is easy to transmit signals to more than 300m, support 4K 60hz, effectively transmit 4K video and audio signals, and is a fever-grade audio and video. User preferred. Of course, for the daily use of our average consumer, the copper core HDMI cable is enough.
Step 5: Do not choose too fine HDMI cable
Under normal circumstances, it is true for the same brand of wire. The larger the wire diameter of the HDMI cable, the larger the cross-sectional area of the conductor, and the higher the current can be transmitted. The final performance is the transmission performance of the HDMI cable. Good and stable. However, there are often many third-line brands that fill the wire in the wire to increase the wire diameter, which makes people look very thick, so first we have to choose the wire of the big brand.
Even with the brand, the HDMI cable that is too thin is definitely not available. The material of the core and the thickness of the shielding layer are all related to the signal quality. The too thin wire must weaken the core and the shielding layer, so be sure to pay more attention. There are four common wire gauges for HDMI. The larger the number, the thinner the transmission distance. So the price will be higher.
In the HDMI cable, the AWG (American Wire Gauge) value is a function of the wire diameter, which is what we often say. The AWG value is inversely proportional to the wire diameter. The smaller the value, the larger the wire diameter, the larger the current can be carried, and the longer the number of meters that support transmission, but the corresponding price is more expensive.
In the industry, the HDMI limit transmission length of different wire gauges will basically be between the following values:
30 AWG limit transmission length 5-8 meters;
28 AWG limit transmission length 12-15 meters;
26 AWG limit transmission length 18-20 meters;
The 24 AWG limit transmission length is 20-25 meters.
To put it simply, in the same length of wire of the same brand, the smaller the wire gauge AWG value used, the better the wire transmission effect will be. If you still don't choose a high-quality, cost-effective HDMI cable, I sincerely recommend the MSL-force HDMI cable here.
