How much do you know about each version of HDMI?

HDMI high-definition multimedia interface (High-Definition Multimedia Interface) is a digital video/audio interface technology that can transmit audio and image signals at the same time, and does not require digital/analog or analog/digital conversion before signal transmission. The content of each version is introduced as follows:

HDMI 1.0

Launched in December 2002, the biggest feature is that it integrates a digital interface for audio streaming, supports video streaming from DVD to Blu-ray format, and has CEC (consumer electronics control) function.

HDMI 1.1

In May 2004, version 1.1 was released. Added DVD audio support.

HDMI 1.2

In August 2005, the much-anticipated version 1.2 came, which largely solved the problems of HDMI 1.1's low resolution and poor device compatibility.

HDMI 1.3

The HDMI 1.3 updated in June 2006 brought the biggest change, which was to increase the single link bandwidth frequency to 340MHz, which also allowed these LCD TVs to obtain 10.2Gbps data transmission.

HDMI 1.4

After 3 years, the HDMI 1.4 version finally lived up to expectations and can support 4K, but due to the bandwidth of 10.2Gbps, it can only reach a resolution of 3840×2160 and a frame rate of 30FPS.

HDMI 2.0

In 2013, the bandwidth of HDMI 2.0 was expanded to 18Gbps, supporting plug-and-play and hot-plugging, 3840×2160 resolution and 50FPS and 60FPS frame rates. It can maintain perfect backward compatibility to HDMI 1.x, and the existing Class 2 data lines can be used directly.

HDMI 2.1

In 2017, the 2.1 version arrived as scheduled. The standard can provide up to 48Gbps bandwidth. The biggest difference from version 2.0 is that the new one not only supports the transmission of 8K and 10K content, but also enhances the 4K resolution output. In addition, another obvious difference lies in the improvement of HDR high dynamic range. The new HDMI 2.1 standard now supports Dynamic HDR (Dynamic HDR).
