How to Choose HDMI Cable HDMI?

These days, HDMI is often the only way to make an HD-capable connection. Although a few TVs still have a component input, it has virtually disappeared on Blu-ray players.

Equipment manufacturers have been required to limit the resolution of component video outputs on HD players and boxes to standard-definition (480i). And for a few years now disc makers have had the option of inserting a “digital flag” into a Blu-ray disc that will limit component video resolution to 480i.

So if you like high-definition and 4K pictures — and who doesn’t? — you’ll definitely want HDMI connections on your gear.

HDMI is the connection of choice for carrying HD and 4K Ultra HD video signals. It can also support up to eight channels of high-resolution audio.

Check the HDMI cable Version

The HDMI 1.4 version cable is the mainstream at the present stage. It perfect support s resolutions up to 4K and 3D content. Although many brands have launched HDMI 2.0 cable, but the HDMI 1.4 cable is enough to meet most of the consumer’s family entertainment needs. It is worth noting that there are some HDMI cables of 1.3 or even lower version sold on market, and consumers should pay attention when purchasing.

Check your HDMI port type

Check your HDMI port type on your TV or display device before buying the HDMI cable. The width of standard HDMI port is 15mm, Mini HDMI port is 10.5mm, and Micro HDMI port is 6mm.

Height: 5mm Height: 2.5mm Height: 2.3mm




Buy the HDMI cable according to the length of the actual requirement

You should select the right length of the HDMI cable when purchasing. It is best to measure the length needed so as not to waste the length of the HDMI cable.

Do not choose thin HDMI cable:

Do not choose those thin HDMI cables regardless of the brand. The material of the conductor and the thickness of the shielding layer are very important to the signal quality. The conductor and the shielding layer of thin cables must be at a discount greatly. HDMI cable has four kinds of common wire gauge 22AWG, 24AWG, 26AWG and 28AWG, which means that the bigger the number, the thinner the wire core and the shorter transmission distance. STC portable HDMI cable adopts 32AWG wire core and aluminum foil shielding that ensure high performance signal transmission.

Quality comes from details

For better long distance transmission, different length requires different wire gauge

1.5-8m: 28AWG OD: 7.3

9-15m: 26AWG OD: 8.5

20m: 24AWG OD: 10.0

Purchase HDMI cable with pure copper conductor

HDMI wire core material plays a decisive role in the cable performance. Those HDMI cables that adopt copper clad steel or copper clad aluminum conductor have high resistance and obvious signal attenuation in the course of signal transmission, especially in long distance transmission. While HDMI cables adopting pure copper conductor can support ultra long distance transmission and ensure signal stability at the same time. STC 30 meters HDMI cable with pure copper can guarantee the signal not to attenuate and support 1080P HD resolution.

Purchase the HDMI cable with gold plated connectors

Now, the HDMI cables with better quality on the market adopt 24K gold-plated connectors, which can effectively solve connector loose contacts problems after repeated plugging and unplugging, so as to avoid signal loss and ensure picture effect

Choose brand HDMI cable and you not worry too much about the details.

If you think it is difficult to judge the advantages and disadvantages of HDMI cable by yourself, the easiest way is to choose the mainstream brand HDMI cable.
