A new version of HDMI is coming soon, and there are some big changes — including support for resolutions up to 10K as well as a new cable. Here’s the skinny on fatter AV bandwidth.
OK, let’s get this done up front. Yes, there’s a new cable with HDMI 2.1, but you don’t need to upgrade. At least not yet.
HDMI 2.1 brings new features and a lot more bandwidth to the venerable cable and connection. HDMI (High Definition Multimedia Interface) is the main audio/video connection for TVs, Blu-ray players, game consoles, video streamers, sound bars, computers and more. It carries both video and audio in one cable, allows digital encryption, and generally delivers perfect video and audio quality without any degradation.
Today’s devices mostly use HDMI version 2.0, but in 2018, many will likely transition to version 2.1. How does that affect you? Not much. You can’t upgrade your current TV to 2.1 spec, but in reality, you won’t need to. This update is quite forward-thinking and takes into account formats and resolutions that won’t be widely available for years.
