However, many customers have not noticed that in the LCD TV publicity of different manufacturers, it is rare to talk about the HDMI interface, but you will find that all 4K Ultra HD TVs will provide this interface, then about our users. Why does this HDMI interface become standard? What does it mean?
First of all, what our customers need to know is: What does HDMI mean? The full name of the English is High Definition Multimedia Interface, the Chinese name is the abbreviation of high-definition multimedia interface. On December 9, 2002, the HDMI organization represented by Hitachi, Panasonic, Sony, Philips, etc. officially released the HDMI 1.0 version specification, marking the official entry of HDMI skills into the historical stage (paperless conference system, ultra-thin one lift, LCD Screen lifter).
And HDMI, unlike the AV cable of a traditional TV set, it needs to separate the video and audio signals. All the transmissions can be easily done with only one line. And the quality of traditional AV line transmission audio signal is much lower than that of HDMI. HDMI can transmit uncompressed high-definition video and multi-channel audio data with high quality, and support more than 1080P picture, which can ensure the highest quality video signal transmission.

As for the 2.0 version of the HDMI interface, you have to know that the current version 2.0 is one of the latest specifications of the HDMI interface. Before that, there was 1.0 and advanced to the previous generation 1.4 version. It not only has all the advantages of the previous version interface. It also greatly increases the signal transmission bandwidth and speed. The larger bandwidth means that the device can have higher resolution, refresh rate and more audio functions. In addition, DMI2.0 also has outstanding backward compatibility, users can appreciate its excellent performance without replacing the once standardized HDMI transmission line.
Although the 4k picture has been supported in the previous generation 1.4 specification, it is not enough for the 4K picture with high frame number. In the user's application process, it will present unpleasant experience such as video picture.
The importance of HDMI is obvious. Various TV manufacturers support the HDMI interface when producing 4K ultra-high LCD TVs, and from the current foreign big manufacturers such as Sony, Panasonic, Samsung, etc., they are now starting to try to HDMI2.0. The version is close, some support the interface when the device leaves the factory, and some can support 2.0 in the later stage through firmware upgrade.
However, from the domestic market point of view, many 4K devices are simply HDMI1.4 interfaces, and even some smart TVs do not inform users at the time of promotion or even the HDMI interface of the first generation versions, from the initial 1.0 to Now the latest 2.0 specification is available on the market, but customers should know that HDMI2.0 is the perfect match for 4K Ultra HD TV. It is also the latest skill specification. Customers must pay attention to the time of purchase.
In the recent newly released Internet 4K smart TV, both the 55-inch and the 43-inch are supporting the HDMI2.0 interface, and it is widely publicized during the promotion period, so that users can purchase and use with confidence. Let users' smart TVs enjoy the latest normative skills in the next few years (paperless conference system, ultra-thin one lifter, LCD screen lifter).
