Has anyone heard about the schedule for the introduction of 4k HD that is 4096 x 2160 pixels. It seems to me to be a little way in the future for home entertainment as TV players and media have still be developed to make it a commercial reality. I think the technology will first appear for projection ofr movies in movie theaters. Any info would be welcome

That and the fact that you'd need a proportionately larger screen to see the resolution benefits. Think we're a way off yet as 1080p hasn't even achieved full market penetration.

Don't have space for a 24 foot screen in my house! I think I'll make do with 1080p but I can see this making a difference for the passive TV crowd.

There's no need when a 32" CRT tv with fully wired gold plated scart and dvd gives yo....... lmfao.

I don't care tbh, blu-ray can't really be topped HD wise atm and I certainly won't go back to two grand for the player that can play the next format to that standard (on which my blu's will probably look like bo11ocks...)

When will the new tv's be on the market?

For the screen sizes most people use 4k will have little benefit.

Agreed but it may have implications for people with home theaters. I cannot see free to air or pay TV operators transmitting 4K material at the moment. Here in Australia the free to air is 1080i or 720p with the horizontal pixels on 1080i broardcasts restricted to a value less than 1920 in order to save bandwith so they can stuff more SD channels on to their transport stream. As for fox tel
they do run hd channels which I think are a mixture of 1080i and 720p. Also there are are problems with the present hd media for
home presentation of movies and tv shows which have a 50G limit for dual layer BD disks and would have to be increased to support a 4k hd material movie length presentation or perhaps we could have an intermission while changing disks,

Saw a 4K video camera (JVC Pro, then prototype, now released) driving a 47" 4K monitor (4 HDMI inputs, each controlling 1/4 screen). The picture was stunning.

To be fair I have a home cinema with a 110 inch screen,but I still do not see a huge benefit over my current 1080p setup.

As with the new iPad with its Retina Display, with 4K you really do not see individual pixels. I can see 1080p pixels on a 47" display.

The new version of Apple's Final Cut X will allow direct editing of RED 4K files. Canon, Sony, RED, and others have 4K cameras.

I saw Casablanca on the silver screen last night here in NYC, and it had been scanned at 4K. Beautiful, flawless "print."

Ready or not, HD is now 4K.

But I agree, I'll be sticking with 1080p for a long while.

And what source are they using for "8K"? The blue-violet laser used in Blu-ray is the shortest wavelength laser possible for a disk. Would multiple lasers be reading multiple layers of a disc in synch? The throughput will require multiple HDMI cables (JVC's solution) or an entirely new cable. (As I said, the 4K picture I saw was a quad array of 1080p pictures from four HDMI cables.) And what about 3D 4K or 8K requiring even more data. Boggles the mind.

You must have Steve Austin's bionic eye if you can see individual pixels on a 47" screen from any sort of reasonable viewing distance!

It is NOT 4K it is 2K !

The marketing propaganda has brainwashed people into misreading a pixel map. The number on
viewer/reader right is the real scientific resolution. So it is 2K not 4K.

Why 4K isn't ready to replace HD

Have gone to the site and read all about it. Looks like it will be a while yet before it takes off let alone replace BR and HD. Disc capacity will be an issue by the sounds of it.

AJR says:
2k is basically the same as 1080p. That's because 1080p specifies the vertical resolution (1080 lines / progressive), but 2k specifies the horizontal resolution (1920 pixels, rounded up to 2k).

4k is the next (big) step, doubling the horizontal resolution to 4k. There are multiple versions, with various resolutions. It's a bit of a mess at the moment.

I think we'll see 4k in cinemas first, because it makes the most difference on really big screens. I suspect it will take a while to reach the home.

Good luck with that James. I've been trying for years to get people to use the correct initialism, but it just isn't happening...
