HMDI 2.1 - higher resolution, higher refreshrate, hello adaptive-sync and more

Yeah, for VR the bandwidth increase seems to be the only really meaningful point. The signalling will be custom to some extent anyway.
That said, I'd hope for VR HMDs (at least those for PC) to largely move to Displayport going forward.

A .1 upgrade that wont work with the .0 version before it....
Sounds like an Apple upgrade

PS4 doesn't have HDMI 2.0. The Pro does, so that's the only one with a chance of being upgraded.

Why? HDMI 2.1 (48Gbps) has higher bandwidth than Displayport 1.4 (32.4Gbps), and they'll continue to leap frog with future versions.
Thanks, I'll add this quote to the OP.
I was gonna say why for movies, but then remembered all my research for my 4ktv and the whole "24hz judder" category.
As long as we get dynamic HDR I think thats all wed need. We can do 4k60 now, as far as console gaming goes
It's shocking to be in 2017 and still have issues with 24Hz playback. TVs 5+ years ago had that sorted out simply by repeating frames.
yes
Yeah, I'd be content if they allowed half-baked compliance and updated to HDR10 with dynamic metadata. The required throughput can't be that significant.
Bonus points for adding RGB 10bit 4:4:4 at 4K60, somehow.

between this, the HDR format war, 8/10 bit panels, different colour spaces and various other things... I'm glad I decided to hold off on a 4K TV until PS5ish time arrives.

Displayport is certainly more flexible from a VR perspective. Built in support for multiple displays for instance could be leveraged with foveated rendering to send multiple different frames simultaneously at different resolutions that are stitched back together at the headset - sidestepping the bandwidth requirements of sending of a single massive high resolution frame where 75%+ of it is a waste of bandwidth. Plus it's here right now and not dependent on who-knows-when general availability.
No hard specifics, but the press release says "4K120Hz", so it would be very odd if it doesn't support 4K60Hz at 4:4:4.
I.......I just purchased a 4k monitor.
Congrats. You have 4K monitor.
Fixed.

The big question is what's required and what's optional.
Was that still not clear enough for some people?
Vendor's implementation of adaptive sync can be called whatever the vendor want to call it. Like FreeSync for example.

Is 48Gbps enough to do 4K120Hz + HDR10 + 4:4:4?
Never heard of blue jean cables(will look into) but monoprice build quality is more than fine if you get their Certified Premium High Speed HDMI cables as you should like this one:
http://www.monoprice.com/product?p_id=15428
Gotta make sure it has that "HDMI Premium certified cable" tag on the picture/box/description.
My PC is pushing 4k 60hz 4:4:4 to my TV right now.
Had to buy a good cable though. Had to toss a 15 ft monoprice cable I had ordered because it didn't work with full bandwidth. I could only get 4k 60hz 4:2:0
I get that when HDMI first hit a cable that works works and nothing else mattered.
Now a shitty cable will prevent you from using high throughput modes and the anything that approaches the full bandwidth of the spec.
Yes that's only around 45Gbps.

Because I was waiting for 4K TV's to atleast reach its peak before buying one since its tech keeps evolving quickly every year and HDMI 2.1 will be futureproof with next gen consoles etc. Consoles tech don't change every single year so that don't count, buying a 4k TV now I thought was still too early for a new premium priced TV waiting till its tech slows down to main features if that makes sense..
Or G-sync. Which essentially puts a lie to their refusal to support adaptive-sync and consequently Freesync displays.
The article clearly states full up- and downwards compatibility. Can't see where you got this from, unless you count not magically getting hardware features via firmware update as "won't work".
This will be 20/20 with a PS5 and a 4K TV in 2020. :]
The double-talk here on what this means to HDMI v2.0 is killing me.
"The new specification, which is formally being announced at CES 2017, will be available to all HDMI 2.0 Adopters and they will be notified when it is released early in Q2 2017."
Seriously, what the hell does that even mean?
I have a year 2015 audio receiver with v2.0 arriving today (Marantz SR7010) and I knew CES week could screw with me, as v2.1 news was expected. But I got happy there for a minute when I read that line.
Now I need to know what extent current v2.0 machines - audio receivers, televisions, video cards, consoles - can benefit from this, if at all.

Supporting something is usually more than giving names to things. But I believe we've already had this discussion. Read more on this from Smith's piece on FreeSync 2 @anandtech if you want, he's done a good job explaining why things which don't sustain themselves financially don't live long.
The adopters here aren't the consumers
The difference here is that Freesync 2 requires a lot more work to implement at all levels, as is clearly explained in that very article. It also notes that G-Sync licenses aren't cheap, so Nvidia wants to push their racket.
Adopter means manufacturers, not you as a consumer. Your 2.0 devices will work basically the same, and you can't just get these new features without replacing the device. The two devices you connect will communicate the features they support and only if both are 2.1 level you will get some or all of the above mentioned.
The spec will be available to existing hdmi2.0 hardware makers in Q2. That was my assumption.
This probable still uses 8b/10b encoding. So we actually have 38.4 Gbps.
It has enough bandwidth even with 12bit/color and 120Hz:
3840x2160x36x120= 35831808000 bits = 35.832 Gbps

Well, finally. Ill upgrade to 4K once this is in tv sets. HDR should be mature by then and the ps5 will be around the corner by the time it's in devices.

What, it will allow all versions of hdmi to work on a 2.1 port.
Obviously you cant get 2.1 benefits on a sub 2.1 port. You can still connect 2.1 devices to sub 2.1 but you're obviously going to lose the pros of 2.1.
That's just how it is. That's like complaining that your USB 3.0 drive isn't getting 3.0 speeds on a 2.0 connection.
This update is huge. It's not a small update at all, especially if you want to game in 4k with HDR
That depends, how big is your bank account?
2019 seems like a safe bet for these features to be standard on lower-end panels.

I wholeheartedly believe that there are good times to jump in and bad times to jump in despite tech constantly evolving. Some tech is bought more often and some tech is bought less often. I feel a TV and AVR are two things are you buy less frequently than more frequently. My current HDTV is 9 years old and still going strong, and in some ways hasn't been outclassed yet since it was top of the line for years after it was released. With 4K HDR sets still being in the early days and very little content out there to take advantage of it, my current set is more than good enough to hold out until a good replacement comes along. Jumping on 4K TVs now is premature still IMO.
LoL - Great point.
And while I know it was a rhetorical question, I'll indulge myself anyway....
Unchanged for the last three round of purchases in ten years: Basically $2500 max for TV, $2200 max for audio receiver.
I'm thinking the late 2018 batch of audio receivers and mid-2019 for televisions. CES 2018 could be really neat, right?

Looks like I'll hold off on buying a 4K tv for another year.

2018 4K oled it is.
Then ppl start screaming for 8K 240hz
But seriously if near future TVs support variable refresh at a reasonable price, along with next gen consoles this will be a good day.
