How to choose HDMI high-definition cable

1. Choose the right brand

2. Check whether there are certification marks on the product packaging. Check if there are HDMI or Simplay certification marks on the product packaging. If there are two association certification marks at the same time, the quality is more guaranteed.

3. Check the version of the HDMI cable Commercially available versions of the HDMI cable range from 1.1, 1.2a, 1.3a to 1.3b. With each new level version, the bandwidth will be greatly increased, and it is compatible with downward support. The bandwidth of the HDMI 1.3 version is now doubled from the original 4.96Gbps to 10.2Gbps, capable of transmitting high-definition videos with higher color depth and high-definition audio. When purchasing, priority should be given to the HDMI 1.3 version of the cable as the best.

4. Whether the connector has a gold-plated HDMI cable, the connector can not be ignored! Currently, the commercially available HDMI connector processes are gold-plated and nickel. From the perspective of transmission effects, gold-plated connectors are better, which can effectively reduce the loss caused by signal transmission. The HDMI cable with better quality mostly adopts gold plating process in the connector part.

5. Wire manufacturing process

Use pure copper as the inner core: Use pure copper as the inner core, which is more conducive to ensuring the quality of the transmitted signal. HDMI with copper core is softer and easier to bend. If it uses iron core or alloy material, it is very hard to bend and the signal transmission is not good.
Moderate soft and hard cable materials: Good HDMI cables are moderately soft and hard. An HDMI cable that is too stiff is not easy to bend, and it can easily slip or tilt when connected, which may cause poor contact. An HDMI cable that is too soft will affect the transmission quality.
Bright and smooth cable connector: The connector process is also one of the key factors that affect the quality of the HDMI cable. Good HDMI cable connectors are generally gold-plated, and the surface is bright, and the transmitted signal is more stable.

6. The cable uses the cable number. The general standard HDMI cable uses the 28th or 30th line, and the diameter of the good wire is the larger 24 or 22 line, because the thicker the core conductor of the wire, the When transmitting high-frequency signals, the signal attenuation will be smaller.
