8K Ultra HD refers to a horizontal screen display or image resolution of approx. 8,000 pixels. The most common 8K UHD resolution is 7,680 x 4,320 pixels. An 8K Ultra HD image has 33.2 million pixels (33.2 megapixels). Specifications of 8K UHD varies in professional fields and thus results in different definitions of horizontal pixels x vertical pixels.

48Gbps is the latest speed for the newest HDMI standard, HDMI 2.1. Gigabits per Second is a measurement of data or network transmission speed. 48Gbps indicates that the speed of a cable or device is capable of transferring or receiving is 48 Gigabits of data per Second.

10K Ultra High Definition refers to a horizontal screen display or image resolution of approx. 10,000 pixels. The most common resolution of 10K UHD is the wide format of 10,240 x 4,320
which equates to just over 44 million pixels (44 megapixels).

eARC or Enhanced Audio Return Channel is the next iteration after ARC. eARC works similarly to ARC, but will support up to 32 audio channels of high resolution 192Hz/24b audio, allowing
audio formats such as Dolby ATMOS, DTS:X and Auro3D to be used for a greater listening experience

Quick Frame Transport (QFT) reduces latency by bursting individual pictures across the HDMI link as fast as possible when the link's hardware supports more bandwidth than the minimum amount needed for the resolution and frame rate of the content. With QFT, individual pictures arrive earlier, and some hardware blocks can be fully powered off for longer periods of time between pictures to reduce heat generation and extend battery life.

Quick Media Switching (QMS) for movies and video eliminates the delay that can result in blank screens before content begins to be displayed.

Auto Low Latency Mode (ALLM) – When a display device supports the option to either optimize its pixel processing for best latency or best pixel processing, ALLM allows the current HDMI source device to automatically select, based on its better understanding of the nature of its own content, which mode the user would most likely prefer.

Variable Refresh Rate (VRR) is a feature that allows content to be displayed in different frame rates during a single viewing session. This reduces or eliminates lag, stutter and frame tearing for more fluid motion in games and media.

Dynamic HDR is the next evolution of HDR video. Standard HDR, works by setting one level of dynamic range when the viewing begins and remains in that state for the remainder of the content.

Dynamic HDR allows different dynamic range levels to be set on a frame by frame basis, allowing content to use HDR when required, which allows for more efficient video transport and more impactful uses of HDR during the content viewing.
