1. Confirm the HDMI version:
The 2.0 version of the HDMI cable is selected because it is a new version and is compatible with the 1.3 version (including the 1.2 version) of the HDMI device. The 2.0 version of the HDMI cable is good for 3D effects (4K 50/60Hz). Since 2011, HDMI official does not allow online HDMI 1.4 or 1.3 characters, but it needs to be labeled: High speed HDMI cable with Ethernet.
2. Determine the core as the standard 19 core:
The standard HDMI version 1.4 cable is 19-pin (19 cores) for HD 3D functionality and stability. Low-end wire is used to reduce costs, using 13-core or under-core HDMI, also known as the simple version. Many devices can also be used to see the so-called high-definition, but the problem of insufficient transmission of current, etc., will result in unstable transmission, the transmission distance cannot be guaranteed, and the equipment (television, computer) will be damaged and accelerated. Especially for users involved in decoration, engineering, etc., it is more important to ensure the quality of the wire.
3. Choose brand word of mouth wire:
Regular brand wire from the materials, processing, testing, packaging and after-sales, have a very perfect body to ensure that the seller's after-sales service, technical capabilities have become an important reference factor; no brand or foreign trade goods should be carefully bought.
4, determine the type of device interface
HDMI has standard HDMI (about 1.4CM wide), MINI HDMI (about 1.0CM wide), MICRO HDMI (about 0.6CM wide), most of the computer and TV are standard HDMI interfaces, you must confirm the interface when selecting the cable, this point Buyers can consult the technical engineers of Tuling Technology.
5, determine the line length
According to the equipment and needs, determine the corresponding line length, different equipment, different applications, the wire quality requirements and length requirements will be different, please be sure to consult the technical engineer of the technical organization; jump out of the misunderstanding of the wire . In engineering use, it is recommended to use the long-line transmitter of the HDMI cable, which can guarantee the transmission quality and improve the stability.
6, HDMI cable is very hard
Very hard lines, generally no shielding. The production is to replace the aluminum foil with a cheap rubber compound and weave it. Usually such inferior lines will add two large magnetic rings, and the appearance is solid, which makes the buyer mistakenly think that the weight is sufficient. The actual HDMI cable below 5 meters, the magnetic ring function is almost zero, the good wire material itself has aluminum foil, weaving and other multiple shielding.
The magnetic ring is just a blind eye.
7, high-priced fever grade wire
8, behind the low-cost wire
There is no shortage of HDMI cable within 10 yuan in the market, the price is very tempting, remember the ancient teaching of a penny. It is recommended that you have your own brand on the packaging of the wire. The people in the industry understand that the brand of the brand should be printed online, which proves that there is monitoring of the raw materials on the line. It is also the embodiment of scale and strength.
