Whats the difference between HDMI 2.0 and HDMI 2.1

Updated: Oct 27, 2022

For 18 years HDMI Cables have been the standard for HD signals to travel from a source to an output. Although the connectors have stayed the same, what’s inside the cable has changed to keep up with new formats and aspect ratios. Now in 2020, HDMI 2.1 is right around the corner ready to become the new standard. But what is the difference from HDMI 2.0 to 2.1?

A diagram showing the different HDMI specicications.

The main difference between the two is HDMI 2.1s massive bandwidth boost. From 18 GBPS in HDMI 2.0 to 48 GBPS in HDMI 2.1. With that increase in bandwidth HDMI 2.1 can carry a 10K Signal up to 120 FPS. The big deal is going to be for 8K picture. HDMI 2.0 can pass an 8K signal, but that signal is capped at 30 FPS. The list of Signals that can be passed via HDMI 2.1 are below.

· 4K50/60

· 4K100/120

· 5K50/60

· 5K100/120

· 8K50/60

· 8K100/120

· 10K50/60

· 10K100/120

When it comes to color both HDMI 2.0 and 2.1 support B.T.2020 and 16 bits per color. Which is perfect for HDR, HDR10+, and Dolby Vision. Their maybe an update in the future to give even more color depth, but that won’t be for a long while.
