HDMI Professional Company Explanation! What are the precautions? The full English name of HDMI is' High Definition Multimedia ', which means High Definition Multimedia Interface in Chinese. The HDMI interface can provide up to 10.2Gbps data transmission broadband, which can transmit uncompressed audio signals and resolution video signals. At the same time, there is no need to perform digital/analog or analog-to-digital conversion before signal transmission, ensuring the highest quality audio and video signal transmission. The advantage of using HDMI is that it only requires one HDMI cable to transmit audio and video signals simultaneously, unlike now where multiple cables are needed for connection; Meanwhile, due to wireless digital/analog or analog-to-digital conversion, higher audio and video transmission quality can be achieved. For consumers, HDMI technology not only provides clear picture quality, but also greatly simplifies the installation of home theater systems due to the use of the same cable for audio/video. At present, HDMI has released version 1.4 with new features including HDMI Ethernet channel, audio feedback channel, HDMI 3D function, 4Kx2K video support, more color spaces, mini HDMI connector, and car connectivity system. When it comes to choosing an HDMI cable for high-definition viewing, it is essential to mention the HDMI cable required for transmitting high-definition signals. Whether it's a laptop or a high-definition MP4, as long as there is an HDMI interface, an HDMI cable will be used. The quality of HDMI cable directly affects the high-definition playback effect. Therefore, when choosing an HDMI cable, there are several steps to pay attention to. Step 01: Confirm the version of the HDMI cable

Pay attention to the version of the HDMI cable, which commonly includes versions 1.2 and 1.3. It is recommended to purchase the HDMI cable version 1.3, which has a higher bandwidth and can meet higher resolutions, refresh rates, and color depths. It can support high-definition playback of 1080P or above. The current 1.4 version of the cable supports higher resolution, which is more conducive to home high-definition TV, and also supports the latest 3D functions. When choosing a 3D cinema, don't forget to choose the 1.4 version of the cable for high-quality 3D effects.

Step 02: Pay attention to the size of the HDMI interface

HDMI interfaces are divided into standard ports and mini ports. Due to size limitations, the HDMI ports on high-definition MP4 are mostly mini ports. Therefore, when selecting an HDMI cable for high-definition MP4, it is necessary to look for a standard mini HDMI cable, otherwise it cannot be plugged in. A small HDMI adapter is needed and needs to be purchased separately~~

Step 03: The longer the HDMI cable, the better

The theoretical transmission distance of a single HDMI cable is 10-15 meters, but in practical use, it does not need to be that long. Before making a purchase, it is best to measure the required length and provide a 50 centimeter margin for the measurement result.

Step 04: Do not choose HDMI cables that are too thin

Regardless of the brand, HDMI cables that are too thin are definitely not suitable for selection. The material of the wire core and the thickness of the shielding layer are closely related to the signal quality. A wire that is too thin will definitely cause shrinkage of the wire core and shielding layer, so it is important to pay more attention.

Step 05: Choose a brand of HDMI cable, which is more worry free

If you find it difficult to judge the superiority or inferiority of HDMI cables with your own vision, the simplest way is to choose branded HDMI cables. Of course, the price will also be higher.

Step 06: Avoid excessive bending of HDMI cables

During the use of HDMI cables, it is important to avoid excessive bending of the wires, such as frequent folding or wrapping, which may damage the core or shielding layer of the cable. Generally curved along an arc, it will not damage the cable.

Step 07: Pay attention to the brightness of the gold plating on the interface

The high-quality HDMI cables on the market now use 24K gold plating, which can effectively solve the problem of poor contact after multiple plug insertions and unpluggations, avoiding signal loss and affecting the picture effect.
