HDMI 1.4 and Through the Ages

[audiophile1882]

I think you are confused, an audio channel and all of the new functions of v1.4 are largely a chipset upgrade! There is only going to be a very small change to the HDMI cable between 1.3 and 1.4. Two previously untwisted wires are now going to be twisted allowing for a transmission of an Ethernet signal (HEC) over a measurable distance. So, pretty much all of the 1.4 features, even the audio return channel, are going to be supported by v1.3 cat2 cables and there will be no firmware update for your previous version HDMI products. If you want to utilize HEC with your devices, you will need to buy a new one...

At least you can keep your same cable, that is unless you cant be bothered to run a cat5e or cat6 cable to your devices....

The way they are going to be able to offer 4k x 2k without increasing the bandwidth is by cutting the refresh rate way down. Max 120hz at 1080p, but with 4k x 2k resolution you are looking at a max of 24hz! O well, not that huge of a deal, but it might make watching a really fast paced, rapid camera movement action flick better in 1080p then in 4k x 2k

In regards to the no titles/hardware bit of the article in relation to 4K.

Don't at least some/many movie theaters project at 2K/4K (although the interface is of course different) so are the titles actually that resolution or are they upscaling the film?

Wasn't nvidia promoting a technology using computer monitors at this resolution? (Even if they haven't reached manufacturing, it is better to have a 'cheap' cable available and no screens than a very expensive screen and no cables to hook it up with)

Edit:
And in response to audiophile1882 it would actually be pretty cool if they could find a way to dynamically adjust the resolution/frame rate being sent to the screen so that slower paced scenes where you want a lot of detail you can have the higher resolution and with high action scenes you could drop the resolution a bit so you don't have a blur effect.

The major issue I could see with this are 1) Transitioning between resolutions without either poor internal filters to get it to native resolution or 2) Jumping between 2k and 4k without sudden changes in the picture. The second option could be taken care of by an instant resolution change in the scene change or even between camera angles.

Edit2:
Sorry, I just realized this was a month old, I saw it on the front page and figured it was a newer post.
