8K is the next wave of high-resolution video and is double the vertical and horizontal resolution of Ultra HD/4K at 7680×4320. There are 33.2 million pixels (33.2 megapixels) in an 8K image.

48 Gbps is the latest speed for the newest standard, HDMI 2.1, which was released in the fall of 2017. At 48 billion bits per second, these cables are transmitting massive amounts of data and thus significant engineering and care is required to pull these off, particularly in distances beyond a few meters.

This connector on this cable requires a minimum of 2 kg (4.4 lbs) of force to remove it from the connected device.

eARC or Enhanced Audio Return Channel is the next iteration found in the new HDMI 2.1 standard. The biggest change in eARC is immersive audio formats such as Dolby ATMOS, DTS:X and Auro3D. These audio formats allow for a greater listening experience by adding audio overhead and in a greater 3D type space, called object-based audio. eARC supports up to 32 channels of high resolution 192/24 audio.
