The connectors are fairly standards. I would love having a 4th (or more) HDMI connector
Buying HDMI cables can already be confusing. This is because, if you didn’t already know, there are actually different versions of HDMI ports and cables. The current “standard” is HDMI 2.1, but it appears that things are going to get more confusing because come CES 2022, the HDMI Forum will be introducing a new version called HDMI 2.1a.
Basically what this means is that this will be a revised version of the HDMI 2.1 standard. It will come with a new feature in the form of Source-Based Tone Mapping. This is a new HDR feature that helps offload some of the HDR tone mapping to the source, like your computer, set-top box, and so on.
The idea is that by offloading some of the tone mapping, instead of having to completely rely on the output device like your TV or monitor, the workload will be shared which means that in theory, it should help optimize the workflow and help reduce lag times, better picture calibration, and more.
As to what this means for end-users, it seems that it might not be something to be concerned about because according to the HDMI Forum, they say that it will be possible for manufacturers to add support for HDMI 2.1a through a firmware update. However, when exactly we will see devices that support HDMI 2.1a out of the box remains to be seen, or when already-existing devices will be updated.
