Is HDMI 2.1 capable of 4K?

HDMI 2.1 fully supports 4K resolution and performs even better under 4K specifications.
Specifically, HDMI 2.0 supports a maximum video transmission of 4K@60Hz, while HDMI 2.1 further improves on this by supporting 4K@120Hz and even higher frame rate 4K content. This means that when playing fast-moving images (such as competitive games, sports events), it can effectively reduce motion blur and smearing, delivering a smoother and clearer visual experience. In addition, HDMI 2.1 is also compatible with features like VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) at 4K resolution, further optimizing gaming and viewing experiences.
