Its use can bring you a new visual experience. Therefore, it is particularly important to buy a high-quality HDMI cable. So, when choosing an HDMI cable, what are your recommendations?
Tips for choosing an HDMI cable:
1.HDMI cable and specifications
There are three common HDMI cables on the market at present, which are 1.3, 1.4 and 2.0. Among them, the HDMI cable version 2.0 will increase the bandwidth of the HDMI cable to 18Gbps, and can support 3840*2160 resolution, 50FPS and 60FPS frame rates. Implemented a new 3D HD display function, support up to 4K*2K HD resolution, and made a number of improvements to audio and video technology. 4 x 1.4 times the 1080P version, with high-speed Ethernet channels, an expanded colorl mode, and a new audio reverse channel.
2.The HDMI cable connector is gold-plated
Connection technology and materials are one of the key factors affecting the quality of HDMI cables. The HDMI interface technology currently on the market has two kinds of gold plating and nickel plating. From the perspective of the transmission effect, the gold-plated connector is better, which can effectively reduce the loss of signal transmission. Good quality HDMI cable connectors are generally gold-plated and have a bright surface.
3.Wire material
Choose HDMI cables that are always hard and flexible. The HDMI cable is too hard and not easy to bend, and may slip or bend when connected, resulting in poor contact. Because the HDMI cable is too soft and thin, it is saved on the material, and the shielding layer may be cut, affecting the transmission quality.
4.The HDMI cable with pure copper core is more conducive to ensuring the quality of the transmitted signal. Soft texture, easy to bend. If the cable is made of iron core or alloy material, the cable is not easy to bend and the signal transmission is not good.
5.Line shield
HDMI cable shielding and anti-interference processing is also very important. Generally speaking, a good shielded HDMI cable is relatively thick at first, and then a little harder and elastic.
