Detail: The HDMI 2.0/2.1 specifications allow for higher frame rates of up to 60Hz at 4K resolution.

This helps to eliminate motion blur and lag while also providing enough bandwidth for HDR and rich color content.

HDR allows photos to obtain larger levels of information in both bright and dark areas of the image by extending the range of both contrast and color.
This function was supported for the first time in HDMI 2.0/2.1

The resolution of up to 4K@50/60 offers the ultimate clarity and video watching experience. It can be simply described as the clarity which is,
4 times more than the clarity of 1080p/60 video resolution and offers advanced audio streams.
