With the popularity of 4K TVs and more and more 8K TVs coming to market, there are more requirements for HDMI video cables for TV transmission. The traditional HDMI version 2.0 cable can hardly meet the 4K 120Hz or 8K 60HZ HD video transmission, so the new CABLETIME HDMI version 2.1 cable is the first choice.

What is the difference between HDMI 2.0 and 2.1?

1, the difference in transmission speed: HDMI 2.0 bandwidth of 18 Gbps, HDMI 2.1 bandwidth of 48Gbps, the transmission speed increased significantly. As you can see, the most obvious difference between the two standards is the bandwidth. The increase in bandwidth allows HDMI 2.1 to transmit more information, which also means that the picture transmitted by HDMI 2.1 will have a higher resolution and higher frame rate.

2, the support of new features: HDMI 2.0 does not support dynamic HDR, HDMI 2.1 supports. Dynamic HDR it allows the content of HDR metadata to be adjusted on a frame-by-frame basis, allowing for better picture quality performance.

HDMI 2.1 also features eARC, an enhanced audio return channel that transmits high-quality, uncompressed audio signals over HDMI cables. In addition, HDMI 2.1 features Variable Refresh Rate (VRR) and Quick Frame Transfer (QFT), both of which reduce latency and potentially eliminate input lag entirely.

3, the difference in resolution support: HDMI 2.0 supports 4K images at 60 FPS or 8K images at 30 FPS. HDMI 2.1 supports 4K images at 120 FPS or 8K images at 60 FPS, as well as supporting 10K resolution.

In more specific numbers, the new HDMI 2.1 standard now supports 7680×4320@60Hz and 4K@120hz. where 4K includes 4096×2160 pixels and 3840×2160 pixels in true 4K, while in the HDMI 2.0 specification, only 4K@60Hz is supported at the maximum.

HDMI version 2.0 supports 4k video playback at 60hz and static HDR data with ideal video effects and no lagging, making it the current standard interface for the 4k industry.

HDMI 2.1 version supports 4k video playback at 120hz per second, while supporting 8k video playback at 60hz per second, dynamic static HDR, eARC, fast speed, high bandwidth, variable refresh rate (VSR) and fast frame rate transmission (QFT) function, no lag is the necessary data transmission interface for the future 8k, 10k era.
