HDMI Version Comparision

Welcome to Zhuhai hanqin Cable Co.,Ltd  ,in this part, we will discuss the comparison of    different version HDMI.

Version 1.4 compared to version 1.3, the most obvious difference is the addition of the Ethernet function (HDMI Ethernet Channel) Support Audio Return Channel (Audio Return Channel) HDMI 3D function 4K*2K@30 video support More color space Micro HDMI connector, Type D Vehicle connection system Type E

Compared with version 1.4, there are no changes to the cable and connectors in version 2.0, so the cable in 2.0 is the same as the cable in 1.4, except that the chips of the Source and sink devices have changed. HDMI in version 2.0 is based on the 1.4 cable. , The signal equalization processing is improved through the device chip to achieve the transmission effect, which is similar to the addition of signal amplifiers to the devices at both ends.

Version 2.0 specifies that 4K is required, and 1.4 and 1.3 do not specify that 4K is required.
Version 2.0 supports 4K*2K@50Hz, 4K*2K@60Hz resolution
The transmission bandwidth has been increased from 10.2Gbps in version 1.4 to 18Gbps
Version 2.0 supports 21:9 aspect ratio/32 channels and 4 sets of audio streams/dual picture/CEC extension/dynamic sound and picture synchronization function
Compared with version 2.0, version 2.1 has higher requirements for wire technology, and the connector has been redesigned.

Higher video resolution supports a series of high resolutions and faster refresh rates, including 8K60Hz and 4K120Hz, enabling immersive viewing and smooth fast action details. Commercial AV, industrial and professional uses also support resolutions up to 10K.
Dynamic HDR support can ensure that each moment of the video is displayed with ideal values ​​of depth, detail, brightness, contrast, and wider color gamut-scene by scene or even frame by frame.
The ultra-high speed HDMI cable supports 48G bandwidth and supports uncompressed HDMI 2.1 functions. The cable also has extremely low EMI radiation, and is backward compatible with earlier versions of the HDMI specification, and can be used in conjunction with existing HDMI equipment.
eARC simplifies connections, provides greater ease of use, and supports the most advanced audio formats and the highest audio quality. It ensures full compatibility between audio equipment and upcoming HDMI 2.1 products.

The enhanced refresh rate function ensures a higher level of smooth and seamless motion and transition for games, movies and videos. They include:
Variable refresh rate (VRR) can reduce or eliminate lag, stuttering and frame tearing, resulting in a smoother and more detailed gaming experience.
Fast media switching (QMS) for movies and videos eliminates the delay that can cause a blank screen before displaying content.
Quick Frame Transfer (QFT) can reduce latency, achieving smoother latency-free gaming and real-time interactive virtual reality.
Automatic low-latency mode (ALLM) allows automatic setting of the ideal delay setting, thereby achieving smooth, lag-free and uninterrupted viewing and interaction.

The selling point of version 1.3 is to support 1080P high-definition picture quality
The selling point of version 1.4 is to support 3D function and Ethernet function
The selling point of version 2.0 is to support 4K ultra-high-definition picture quality

Note: Since the HDMI2.0 version does not have a new definition of the cable and connector, only the Source and Sink have been changed, so the HDMI2.0 cable still refers to and uses the HDMI1.4 version of the cable specifications and test standards, that is, if it passes 2 All HDMI1.4 cables of cat2 (cat2) can be used for HDMI2.0 transmission.
