What is HDMI?

HDMI stands for High Definition Multimedia Interface. It's a standard for connecting high-definition video devices and it is the primary audio/video connection for TVs, Blu-ray players, game consoles, set-top boxes. It allows both video and audio to pipe through one cable, without any degradation, and it allows digital encryption. Now at the CES show, we have HDMI 2.1

What is HDMI 2.1

48Gbps vs. 18Gbps in HDMI version 2.0. This will require a new cable

Max resolution of 10K @ 100/120 refresh, getting (and 8K @ 60) this resolution requires a new cable

Connectors will not change

HDMI ver 2.1 is backward compatible with previous versions

HDMI ver 2.1 covers more of the visible spectrum and color gamut

HDMI ver 2.1 brings enhanced and finer control of brightness levels throughout the video with Dynamic HDR

This larger data transfer capability means it will now be able to carry a video signal of resolutions of up to 10K. The increased resolution and frame rate possibilities are a futurist's dream:

4K 50/60

4K 100/120

5K 50/60

5K 100/120

8K 50/60

8K 100/120
