PCMag put out an article: Next Version of HDMI to Use New, Higher-Capacity Cable

In a nutshell, CES 2025 should have a HDMI Forum event Jan. 6th likely to bring the arrival of an update to the HDMI standard, it'll offer higher bandwidth for more resolutions and refresh rates, and will be 'supported' (I'm guessing require?) a new HDMI cable (ah, a new cable to buy!).

On the other hand, it says the latest HDMI 2.1b spec can technically support 4K, 8K, and even 10K resolution up to 120 frames per second.

So I wonder what practical benefit a higher bandwidth version will offer?

The article also notes HDMI 2.1 came out in 2017. Even this year and late last year, I believe a numbers of Windows PCs didn't support HDMI 2.1, rather using earlier versions. So 7 years after release, 2.1 hasn't fully caught on.

So my question to you guys is this - if HDMI 2.2 gets released in January, how much practical benefit do you think it'll offer, and how compelling a feature do you think it'll be?

So far, if M5-series Macs are released next year, they'll likely offer a modest performance gain coupled with Wifi 7. Will a new HDMI standard entice more people to buy M5?
 
DisplayPort 2.1 can do up to 77.37 Gbps. HDMI 2.1 is limited to 42.67 Gbps. I don't think anyone mentions what speed HDMI 2.2 will have. I suppose it should be in the DisplayPort 2.1 range or beyond.
