HDMI 2.1a to get new standards for next-gen HDMI displays, including Source-Based Tone Mapping

We recently reported that the HDMI Licensing Administrator stopped labeling newer HDMI displays with the 2.0 version, and allowed manufacturers the power to utilize the HDMI 2.one moniker, as long as information technology fits the standards already gear up. This potentially tin can cause a manufacturer to characterization an HDMI 2.0 display as the 2.1 version to falsify claims to consumers and was seen by a Chinese seller practicing that verbal scenario.

Now, at that place is a new HDMI ii.1 variant nearly to be released at some point in the futurity with the moniker of "HDMI ii.1a."

The HDMI Licensing Administrator confirms new standards for HDMI two.1 with the addition of SBTM

What is currently odd is the information most HDMI 2.1a, equally information technology will be presently called, was actualization on the Licensing Assistants'south page just has since mysteriously disappeared with no explanations. It is possible that there are a few last-minute decisions to finalize the new standard for use, but that in and of itself is pure speculation. VideoCardz has mentioned that the information tin be constitute via Google Cache. One of the newest additions to the HDMI 2.1a is the employ of Source-Based Tone Mapping or SBTM.

Source-Based Tone Mapping (SBTM) is a new HDR feature that allows a portion of the HDR mapping to be performed by the Source device instead of the Brandish device. SBTM is especially useful in cases where HDR and SDR video or graphics are combined together into a single motion-picture show, such as picture-in-picture show or a program guide with an integrated video window. SBTM also enables PCs and gaming devices to automatically produce an optimized HDR signal in order to maximize the utilization of the display's HDR capabilities without manual user configuration of the Source device.

Gamers and PC enthusiasts will see the nigh apply of the new technology, due to the ability for multiwindowed environments. The source device, in essence, controls the tone mapping. This process allows dissever windows to display either SDR or HDR optimized content simultaneously. TFTCentral states that the new SBTM is non a replacement for the current HDR technology (HDR10 and HLG, also as other offerings). SBTM is set to deepen the HDR experience by offering more capability for optimization with HDR-capable devices.
