Main differences between HDMI 2.0 & HDMI 2.1

HDMI 2.0 and HDMI 2.1 are the latest versions of the HDMI standard, which is used to transmit audio and video between devices such as TVs, computers, and gaming consoles.

While both HDMI 2.0 and HDMI 2.1 offer significant improvements over previous versions, there are some key differences between the two that are worth considering.

HDMI 2.0 supports a maximum bandwidth of 18 Gbps, which is enough for most applications, including 4K video at 60 Hz and 8-channel audio.

While HDMI 2.1, on the other hand, supports a maximum bandwidth of 48 Gbps, which is more than enough for 8K video at 60 Hz and 16-channel audio.

Another difference between HDMI 2.0 and HDMI 2.1 is the ability to support variable refresh rates (VRR). HDMI 2.0 supports VRR at a maximum refresh rate of 60 Hz, while HDMI 2.1 supports VRR at refresh rates of up to 120 Hz.

This can be useful for gaming, as it can reduce screen tearing and improve the overall gaming experience.
