Specification supports 4K video and 32 channel audio

The HDMI Forum is a nonprofit association that manages the HDMI specification. Today the HDMI 2.0 specification has been officially unveiled and is available for partners to download right now. HDMI 2.0 promises significantly increased bandwidth allowing new features.

HDMI 2.0 supports bandwidth of up to 18 Gbps. That gives the specification the bandwidth to support 4K 50/60 resolution video -- that is four times the clarity of standard 1080p/60 video. HDMI 2.0 also supports 32 audio channels along with dynamic auto lip-see and extensions to CEC.

HDMI 2.0 is backwards compatible with earlier versions of HDMI, and perhaps the best news is that HDMI 2.0 doesn't require new plugs or new cables. Existing high-speed category two cables are already capable of carrying the increased bandwidth provided by HDMI 2.0.

The HDMI 2.0 specification is available for adopters to download via the HDMI Adopter Extranet. A press conference will be held to discuss the new features of HDMI 2.0 at IFA 2013 in Berlin this Friday.

No it's not, 60hz is not enough, particularly for 3d (when it becomes 30hz).

4K at 120hz would be better - either for 120hz gaming or 60hz 3d.

The original content is most likely 24fps so 48fps for 3D would be fine with 3:2 pulldown I think its 96fps where it gets super smooth.

There are cases like Football where I would like the 120hz or better for 3D but if the source is 60hz well its just trickery anyhow.

The thing is when you get to silly high resolutions you get diminishing returns for all that effort. Other things have more impact - better colours, less blurring and higher refresh rate. 4K needs those things too or people might just prefer 1080p with everything else over a flawed 4K screen. By maxing refresh @ 60hz they have already limited what 4K screens can do.

3D? Is this 2010? It died, get over it.

Its entirely possible, supposedly you need an 80" and up size TV to see the difference. What percent of homes do you think fit into the category?

4k is mainly for projectors, but you will definitely see a difference in 4k vs. 1080p at 80". Why not check for yourself before pretending you know?

Heck, if you've actually seen 4k on a 55" display the difference is obvious at as much as 8' and plenty of people set their couches closer than that.

my only interest in 4k if for a computer. in terms of computers, it will keep climbing

Same here.

I'm only in the market for WQHD 27" LED LCD monitors (2560x1440) as there IS content on the PC front! Dev work, gaming, graphic work - if your PC can drive the pixels then you get WQHD goodness.

Off topic ish but I'm waiting for IPS 120hz WQHD 27" monitors to be cheaper, no bleeding and some soft of dead pixel warranty (maybe 2 years or so for me).

On topic, in Australia we don't have 1080P TV content (over free-to-air / freeview or even Foxtel) - so why on earth go to 4K. Maybe we'll have 1080P content in a few years. Maybe we'll have 4K content by 2025. I'm not buying a 4K TV while I wait.

Oh man, is Australia living in the stone age? Who gets their content via OTA broadcast?

imho we're about 5 years behind most developed nations, in regards to Internet connection, TV streaming services, OTA broadcasting.

It's a shame, though we're a massive country (6th largest), with a small population (22.32 million) so we can't simply (read: cheaply) catch up by laying cables.

Err... those who don't want to pay for TV content? Australia has about 20 digital channels and that's more than enough to cover American junk (CSI, NCIS, Law & Order, etc). See http://www.yourtv.com.au/guide.

TV content? Jesus. This is for movies and, eventually, games.

TV content... as if it is worth it to buy an expensive TV just to watch whatever passes for TV content these days...

I haven't sat down to watch TV in about a decade.

cant believe I accidentally upvoted this, wish I could change it.

if 4k doesn't benefit you at 80" then congrats you can even see the tv at all Mr Magoo.
What kind of nonsensical statement is this?
The human eye has enough resolution to spot greater than 1080p at under 50 inches if you have 20/20 vision... nevermind 80

You have changed it by replying.

As soon as you comment all your votes on the article are scratched - unless I'm mistaken (someone confirm?).

And next, 4K will die. It's just not a benefit in most consumer homes. Even with my 80" TV the benefit would only manifest when I'm standing directly in front of the TV.


No it won't. Going from 720P to 1080P was a relatively small jump and it was very noticeable. Going from 1080P to 4K is 100% resolution improvement, so with the approriate content you will see a substantial improvement.

What kind of improvements?

Dynamic range, in particular, because for a given gradation you will have more pixels per area to represent transitions from bright to dark as well as between various colors.

You will also see far more detail, sharpness and clarity. Great not only for movies and TV shows, but for gaming.

Worried about a lack of 4K content? Don't be...because many people now get their content from online streaming services, the adoption of 4K content doesn't require broadcasters to be "on board". Youtube already supports 4K video and it's likely that Amazon Prime and Netflix will too...and don't forget about the pirate bay. Most modern films and TV shows were originally shot in 4K; most theater projectors have been 4K for years so there is an abundance of content, with many production companies already equipped to shoot and process 4K video.

Lastly, the correlation of screen size to screen resolution has more to do with the viewing distance and your own visual acuity. The human eye is very capable of resolving more detail than 1920x1080 on a 50 inch screen - if you don't see a difference it's time for a new glasses/contacts prescription. You probably didn't think a smartphone needed a 720P screen since it's only 4"...until you saw how much better it is with a 720P screen that 480P or less.
