New gear won't be out this year with HDMI 2.1

One year later and here we are.. on the cusp of 2.1
It may take a while to stabilise... but I suspect mainstream AVR and TVs will have it by mid year.. so if you can tahan, things will be pretty exciting..

Everyone just relax. Let the new specs marinate first before jumping to it.

If talking about cables, I believed it will retain the high speed vs standard speed naming convention but with clear indication that it support up to 8k. I recalled reading somewhere in HDMI.org that the new fable will be marked as ultra high speed but number versioning should be refrained for product marketing/packaging. Maybe others can chip in as I might be wrong.

These cable upgrades are a PIA for ceiling-mounted projector users.. for my case I will need to rework the cabling concealment furnishing (i.e. breaking/reinstalling false ceiling, painting, etc.) which will involve a few renovation vendors. :(

I’m redoing my projector runs soon. Going to do dual fiber HDMI runs for redundancy. It’s a pain, but a necessity. I recommend for anyone to make the cable path in such a syvthst it can be easily replaceable by yourself.

HDMI 2.1 is on the way
A lot of new cables ?
Best to run a guide cable to pull the old ones out..
https://lifehacker.com/what-you-need-to-know-about-hdmi-2-1-and-8k-tvs-in-2019-1831842410

"HDMI 2.1 versus 2.0 (and 2.0a and 2.0b)
HDMI technology has gone through several revisions and updates over the years. The current standard, HDMI 2.0, replaced HDMI 1.4 in 2013 and updated the technology to support 4K Ultra High Def (UHD) video at 60 frames-per-second, plus a number of AV features. Better still, it didn’t require you to have to travel to the dust-covered lands behind your TV and swap out all your HDMI cables.

Two interstitial updates—2.0a and 2.0b—expanded High Dynamic Range (HDR) support for HDMI 2.0, but are otherwise identical to 2.0 and also use the same cables.

HDMI 2.1, on the other hand, is an entirely different beast.

The main difference is that HDMI 2.1 increases your maximum signal bandwidth from 18Gbps (HDMI 2.0) to 48Gbps, which enables video resolutions of up to 10K and frame rates as high as 120fps—numbers that seem grossly unnecessary given current hardware realities, but impressive nonetheless. And future-proofed, so you (hopefully) won’t have to upgrade your cables or connectors for some time.


HDMI 2.1 also brings a number of other A/V features and enhancements, including:

Dynamic HDR, which is capable of changing HDR settings on a frame-by-frame basis.
Enhanced Audio Return Channel (eARC), which enables the use of object-based surround sound formats, such as Dolby Atmos.
Variable Refresh Rate (VRR), Quick Frame Transport (QFT) and Auto Low Latency Mode (ALLM), which are helpful for video games since they reduce input lag, latency, and refresh rate for smoother, more accurate gameplay.
Quick Media Switching (QMS), which removes the delay when switching between resolutions and frame rates.
Aside from the higher signal bandwidth and new features, the other notable difference between HDMI 2.0 and 2.1 is that 2.1 will require new cables—something HDMI 2.0 mercifully did not, despite being a massive jump from HDMI 1.4.

These new cables, which are being called “ultra high speed” cables, are what enable the higher resolutions and refresh rates, but you don’t need to worry about buying them any time soon. Ultra high speed cables will only be required for the higher resolutions and framerates, while the additional HDMI 2.1 features (like eARC, Dynamic HDR, and the latency-reducing benefits) are compatible with most current HDMI cables.

Unfortunately, it will not be possible to update an existing HDMI 2.0 device to support HDMI 2.1 features via firmware or software updates; the only way to utilize HDMI 2.1’s features is by connecting an HDMI 2.1 device to an HDMI 2.1-supported TV (even if that connection is via a non-ultra high speed HDMI cable).

Here’s where it gets confusing, however. Depending on the device, “HDMI 2.1 support” might mean different things."

Thanks Pete for sharing...

So the only difference is with the higher refresh rate - e.g. 8K@60fps or 4K@120fps which will require a HDMI 2.1 cable. Other than that, the other new HDMI 2.1 *features* like eARC for instance can still be activated on the current HDMI 2.0a/b cable.

SONY's higher end TV models tested on DTS:X and ATMOS pass thru via eARC. Pity...PANASONIC models not tested.

+1...any "significant" improvement to the overall PQ/SQ? I dun suppose so for normal 8-bit 4:2:0 bluray? I could be wrong...
