HDMI is currently the most popular audio and video interface in the audio and video market, covering a number of areas such as TVs, PC computers, monitors and cell phones, and the HDMI standard has been upgraded from the previous 2.0 to 2.1. Although the HDMI 2.1 standard was released as early as 2017, it was not popular enough due to the lack of high resolution and high refresh rate video resources until the end of 2019, when there were gradually equipped with HDMI2.1 TVs are listed.
This has led to many users until today do not know much about HDMI 2.1 standard, so today we will talk to you about what is HDMI 2.1 standard, and what is the difference between it and HDMI 2.0.
HDMI 2.1 standard was born in 2017 and is a technical standard for future ultra-high quality audio and video transmission. The biggest difference between HDMI 2.0 and HDMI 2.0 is the bandwidth. HDMI 2.0 has a transmission bandwidth of 18Gbps, while HDMI 2.1’s bandwidth is upgraded to 48Gbps, and the increase in bandwidth directly brings an increase in the amount of transmitted data.
Secondly, HDMI 2.0 does not support 8K video transmission, while HDMI 2.1 can support not only up to 4K 120Hz, but also 8K 60Hz.
In addition, HDMI 2.1 also supports VRR (Variable Refresh Rate). It is used for gaming to reduce or eliminate screen latency, lag, and tearing to ensure smoother and more complete game details.
HDMI 2.1 also supports ALLM (Automatic Low Latency Mode). In Auto Low Latency Mode, instead of having to manually switch between low latency modes based on what the TV is playing, Smart TV users will automatically enable or disable low latency mode based on what the TV is playing. This enables smooth, lag-free, and interruption-free viewing and interaction.
HDMI 2.1 also supports Dynamic HDR, while HDMI 2.0 only supports Static HDR.
In a nutshell, with the addition of HDMI 2.1 technology, the picture presented by the TV is clearer and more realistic, with richer colors, better audio and visual effects, and less delay and lag in the picture.
So, for users, it is necessary to upgrade to HDMI 2.1 interface? The answer is not necessarily.
If you are a gamer, for a better experience, it is still necessary to get a 4K 120Hz TV that supports HDMI 2.1. If you usually just catch up with the drama, see the video, then you can temporarily wait and see, and then get HDMI2.1 full popularity is not too late.
