HDMI 2.0b – Another small update in 2016 adding HLG HDR support. HDMI 2.1 – Released in 2017, supports higher resolutions up to 10K and bandwidth up to 48 Gbps. Key enhancements for gaming and home theater. HDMI 2.2 – Introduced in 2020 as an update to the content protection specification HDCP 2.2 rather than the core video interface. Note that the 48Gbps per second and the 80Gbps quoted above are the raw HDMI 2.1a and DisplayPort delivery speeds respectively. DisplayPort 2.1 has four lanes that can deliver approximately 77 And then comes HDMI 2.1, which bumps the bandwidth to 48 Gbps. This bigger difference in bandwidth lets HDMI 2.1 cables to handle 4K resolution in higher frame rates – 4K at 120Hz and 8K at 60Hz HDMI 2.1 spec released, ushering in new era of dynamic HDR video. It turns out that TV and monitor makers don't actually need to support those marquee HDMI 2.1 features to claim HDMI 2.1 The Zeskit Maya is the best HDMI 2.1 cable for most people. It comes in various sizes from 0.5 meters to 3 meters and has braiding for added durability. Plus, the cable is Ultra High-Speed HDMI-certified. So you know that you can enjoy everything from 4K games at 120Hz and VRR to Dynamic HDR and eARC without issues. The 18Gbps on the HDMI 2.0 gives you an output in both 4K and 8K resolutions, and at 60fps and 30fps, respectively – which is still high picture quality for regular viewing. However, the massive 48Gbps on the HDMI 2.1 gives you even more: you get better video performance; 4K resolution at 120fps and 8K resolution at 60fps. The key difference is simple: “HDMI input ports receive the audio/video signal, while HDMI output ports transmit the audio/video signal. Inputs are found on displays, while outputs are on source devices like laptops and media players.”. However, it goes much deeper than that (literary!). While there’s little 8K content available at this time, you can still future-proof your home entertainment setup — and 8K HDMI 2.1 is the gateway to get there. Ultra-high-speed data transfer for lag-free gameplay, extreme audio, vibrant colors and crisp details are some of the more popular 8K HDMI 2.1 features that will let you fully engage in a stellar gaming experience. HDMI has been carrying pictures and audio from source to receiver since its inception in 2004. But when ARC launched in 2009, it opened up HDMI to sending audio both ways – known as ULqXojT.
