When HDMI 2.1 isn’t HDMI 2.1

If you’ve followed the display, graphics card or games console market at all recently you will surely have heard about HDMI 2.1. It’s the new connection interface standard widely being adopted on new graphics cards, displays, games consoles and other devices; allowing support for improved bandwidths, resolutions, refresh rates and features. It’s one of the hot topics at the moment when it comes to buying a new device, and promoted heavily by manufacturers, often as one of the leading items in their spec.

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.

Oh good. More weird cable and port specifications to worry about.
