What Are The Differences Between HDMI 1.0, 2.0 and 2.1

Like all electronic specifications, HDMI has alot of details that consumers and even tech’s just don’t need to know.   Things like twists in the cable and the designation of power on certain pins are usually only of interest to manufacturers.  Below are the HDMI specs we think most consumers will care about.

HDMI 1.4 supports the past while HDMI 2.1 supports the future which a maximum resolution of 10K at 120Hz.  Nothing on the market today performs to that spec, but it will be here sooner than you think so if you want to buy a high end cable, we suggest you consider the HDMI 2.1 (when you can actually buy v2.1 cables!)

Below is a table of all the notable HDMI specifications you are likely to run into and the the last 4 items have links to solid articles that explain the feature in detail:
