In this article we want to look at what the “HDMI 2.1” term really means, and address a worrying early sign in the market of things to come. We’ve delved in to what is required for this certification and what that means to you as a consumer if you ever want to buy something labelled with HDMI 2.1. Don’t make any assumptions about what that will give you, sadly it doesn’t seem to be nearly as simple as that.
The people who write the HDMI spec should get together with those behind USB-C so they can create a single port that nobody understands.
