Over at CES 2022, the HDMI 2.1a standard will be revealed.
Here’s a bit of a breakdown as to what to expect:
Let’s start with the good: HDMI 2.1a is an upcoming revision to the HDMI 2.1 stack and adds a major new feature, Source-Based Tone Mapping, or SBTM. SBTM is a new HDR feature that offloads some of the HDR tone mapping to the content source (like your computer or set-top box) alongside the tone mapping that your TV or monitor is doing.
In short, there’s some nifty stuff en route, and it’ll be interesting to see how Apple adapts to this via either new hardware or updated firmware.
Stay tuned for additional details as they become available.
