HDMI 2.1a – New next generation standard introduced

The current HDMI standards are currently very poor and are supplemented by the new version HDMI 2.1a. Meanwhile, the previous HDMI 2.1 is softened, which helps to deceive the manufacturers.

First, HDMI Licensing LLC plans to introduce New Standard 2.1a, Which, according to initial reports, supports a new feature called Source-Based Tone Mapping (SBTM). The explanation for this is that it adds an HDR feature that allows a portion of the HDR mapping to be executed by the source device instead of the display device.

“SBTM is especially useful in cases where HDR and SDR video or graphics are combined into one image. A program guide with a B-Picture-in-Picture or integrated video window. Helps to generate HDR signal automatically.

The purpose is to simplify the process for the user to automatically output the best HDR image based on current content. Sony has something similar With the latest flagship PS5 firmware Enabled, here it is called Automatic Type Mode Mode, which currently only works in conjunction with the latest Provia TV sets, but is currently worse than perfect as tests show.

HDMI 2.1 softened

Made even these days A message is coming around, After which the HDMI 2.1 standard is slightly softened. In the future, buyers should carefully consider what features their device supports and no longer trust the HDMI 2.1 specification.

The background to this is that even if a manufacturer still relies on HDMI 2.0, it is possible to include HDMI 2.1 in the manufacturer’s specifications if it enables the unique features that make up the HDMI 2.1 standard.

A Chinese manufacturer is already using this on one of its PC monitors, causing buyers dissatisfaction and they may feel cheated here. The only way to ensure this in the future is to ensure specific features such as 8K, 120hz, VRR or ALLM as defined with HDMI 2.1.

As for the future of HDMI 2.1a, you don’t have to worry much until it’s actually available on first devices. This does not require a hardware upgrade.
