The main differences between HDMI2.1 and HDMI2.0 are reflected in the following aspects:
1.Bandwidth capacity: The transmission bandwidth of HDMI2.1 is 48Gbps, while the bandwidth of HDMI2.0 is 18Gbps. This increase in bandwidth can lead to faster transmission speeds and larger data capacity, supporting higher resolution and refresh rates.

2. Resolution and refresh rate
In terms of video output, HDMI 2.1 can achieve resolutions and refresh rates that HDMI 2.0 cannot achieve. HDMI 2.0 can support video output up to 4K 60Hz, while HDMI 2.1 can not only support video transmission up to 4K 120Hz, but even 8K 60Hz. This meets people's growing demand for ultra high definition content.
Another major difference between HDMI 2.1 and HDMI 2.0 is their support for High Dynamic Range (HDR) technology. Although HDMI 2.0 is limited to static HDR, HDMI 2.1 introduces dynamic HDR support, allowing for more precise and vivid HDR content to be provided through dynamic metadata. This enhancement enhances contrast, brightness, and color accuracy, providing users with a more realistic and immersive visual experience.
In addition to advancements in video functionality, HDMI 2.1 also brings new features to meet the constantly changing needs of modern multimedia devices. This includes enhanced audio return channel (eARC) support, which allows users to enjoy high-quality audio output without the need for additional audio cables. Not only that, HDMI 2.1 also introduces variable refresh rate (VRR) technology, which can dynamically adjust the output signal based on the display's refresh rate, avoiding screen tearing and lagging, making it an ideal choice for gaming enthusiasts. This feature enhances the overall gaming experience by providing smoother and more sensitive visual effects, ultimately providing a competitive advantage in fast-paced gaming scenes.
