8 Must-Know Tips on Choosing the Best HDMI Cable

Choosing the Best HDMI Cable

HDMI cable has made its way to zillions of households. However,  many users feel confused to choose the best quality HDMI cable in the face of multiple market brands! In order to solve the problems, today we will talk about this topic.

First, let’s recognize the dangers of a poor quality HDMI cable (http://www.vnzane.com/product/high-speed-hdmi-cable-male-to-male-vn-h835/).

HDMI video cable is the link between broadcast equipment and display equipment. Its quality directly affects the display of TV. High-quality HDMI cables can form a “fast transmission channel” between input devices and display devices. So, data information can be transmitted without interference, significantly improving the user’s audio-visual experience.

A poor-quality HDMI cable is easy to have display interfaces, such as edge shadow, color bias, water ripple, and other phenomena. The display parameters that should be automatically identified can not be done successfully. Most of them are with 13 cores or 15 cores, and the necessary shielding layer removed, which affects significantly on the signal quality. They are prone to have blinking, snowflakes, black screen, color unsaturation, poor sound quality, and so on.

After recognizing the hazards of poor quality HDMI cables, let’s learn how to buy a suitable one:

1. Inner Core Material

HDMI cables generally used internal core materials: A. oxygen-free copper wire, B. recycled copper (low copper content), C. copper-clad steel, D. copper-clad iron.

The standard HDMI cables are usually made of high purity oxygen-free copper.

Non-standard products generally use cheap copper-clad steel or even copper-clad iron. Their transmission performance is far inferior to that of pure copper core wires, even less than 1080P signal transmission effect, which can not guarantee high-quality signal transmission at all.

2. Number of Inner Cores

Standard HDMI cable: full PIN 19 + 1 core, a total of 20 cores, in line with the standards of HDMI Association.

Non-standard HDMI cables: jerry-building method, remove the ground wire, usually made into 13 + 1 core or 15 + 1 core. At present, the non-standard HDMI cables sold in the market generally have four shielding wires and two functional wires less than the standard version, which greatly reduces the effect of signal transmission.

3. Shielding Material

The standard HDMI cable is robust with PVC. It takes a lot of effort to disassemble it. Generally, it can’t be torn by hand. It can only be cut by scissors or pliers. The outer PVC with inferior materials can be torn by hand. After shearing the first layer of PVC shielding layer, we can see that there are a high density and durable metal Al-Mg shielding layer, which can only be cut with scissors; and the third layer is the aluminum foil shielding layer. The core of 125% aluminum foil coating has a stronger shielding effect. The formation of multi-layer shielding can effectively resist interference and make the signal transmission more stable.

Non-standard HDMI cables have no shielding layer and can not block the interference of external environment on the standard transmission of signals.

4. Wire Thickness

Usually, the larger the diameter of HDMI cable is, the larger the cross-section area of the conductor is, and the larger the current can be transmitted. Finally, the transmission performance of HDMI cable is good and stable. But some manufacturers will fill the inferior wires with impurities to increase the line diameter, making it looks thick, so it is not always the thicker, the better.

5. Metal or Plastic Handles?

As far as the final performance of HDMI cable is concerned, there is no difference between metal grip and plastic grip. But the metal head HDMI cable looks higher, stronger and more beautiful, and the cost of the metal head is relatively high. Therefore, in this regard, you could depend on individual preferences to make a purchase.

6. Flat or Round?

From the bending point of view, the circular line in any direction can resist large bending force, while the flat line could only resist small bending force from two directions; and for the other two directions it can not be bent. For the decoration wiring, the flat cable will be more convenient to use than the circular one, and it performs better to save space, bury and install in the wall.

In terms of internal structure, the twisted pairs of circular wires are closely inter-twisted, while the flat wires are arranged in parallel. The anti-interference performance and transmission effect of circular wires are better. But in an environment of low disturbance and small distance, there is almost no difference between the two.

7. Functional Testing Effect

High-quality HDMI cable: It conforms to the standards formulated by HDMI Association, accomplishes the transmission mission of high quality, restores the essence of audio and video perfectly, and make the image more vivid and colorful; to fully demonstrate the technical advantages of HDMI.

Poor quality HDMI cable: color difference or insufficient bandwidth can cause instability in playback. It is prone to poor contact, poor interference ability, and other phenomena, resulting in the display of image flicker, weak effect, black screen, and other aspects.

8. Version Differentiation

Market HDMI cable version ranges from 1.3 version, 1.4 version, 2.0 version, to the latest version 2.1. For each new level version, bandwidth will be greatly improved, and downward compatibility can be supported. At present, HDMI 2.0 (more info) and HDMI 2.0 versions has a specification with maximum support of 18Gbps transmission bandwidth, much larger than the previous versions, and this is achieved without the need for users to buy new cables alone. By optimizing the transmission signal, it can transmit faster video losslessly in the same cable. Now it’s better to choose wire material to consider version 2.0.

High Speed HDMI Cable Male to Male VN-H835 from Vnzane has the versions of 1.3/1.4/2.0. The display could reach 1080P 3D image, and it has a 4D high definition. The high-quality core is another vital part to ensure its ultimate effect. With almost 30 years of experience in high-performance cabling, Vnzane could always provide cable products and services catering to customers’ needs.  The fact that it has passed the RoHS, CPR, CE, ISO9001, SGS, etc. and gained lots of certifications and awards could set your mind at rest to make a purchase.

Now you have learned some skills to select an exceptional-quality HDMI cable. Besides the cable itself, the manufacturer could be of equal importance. Vnzane is an outstanding supplier in this case for you to consider.
