The HDMI 2.0 channel was designed to achieve a maximum transfer rate of 18 Gb / s, which allows this standard to transmit signals with a resolution of 4K UHD up to 60 FPS. However, this is not the only improvement we will benefit from if we correctly identify the HDMI connectors of our TV.
Benefits Not Only in Video
This standard has 32-channel audio transmission in which dynamic audio and video are synchronized, the number of CEC protocol commands increases and the maximum audio sampling frequency is 1536 kHz, which allows the use of 192 kHz sampling in configurations with 7.1-channel topology.
This has become especially important with the advent of new 3D audio formats such as Dolby Atmos and Auro 3D.
This is possible because the 2.0 standard proposes a signaling method that can take advantage of the means of transport (the cable) in a more efficient way, exceeding the 10.2 Gbps proposed by the 1.4b standard to reach 18 Gbps of standard 2.0.
Except for HDMI 2.0 ARC
But it is worth it because HDMI ARC accurately broadcasts a full-fledged Dolby Atmos or DTS: X.
The ARC protocol contained in the HDMI 2.0 specification can only transmit PCM, Dolby Digital, and DTS audio, and it is not possible to work with formats such as Dolby TrueHD, DTS-HD Master Audio, Dolby Atmos and DTS: X.
