4K resolution hardware will officially be called ultra HD

The Consumer Electronics Association (CEA) has announced the official name for the next generation 4K high-definition display technology: "Ultra High-Definition" or "Ultra HD." According to the CEA, the name is intended to infer the new format's superiority over conventional HDTV.

The CEA Board of Industry Leaders voted unanimously this week to recommend the previously mentioned names for the new next-generation HD resolution. Along with agreeing on a name, the CEA also outlined minimal performance characteristics to help consumers and retailers understand the benefit of the new technology set to begin rolling out this fall.

“Ultra HD is the next natural step forward in display technologies, offering consumers an incredibly immersive viewing experience with outstanding new levels of picture quality,” said Gary Shapiro, president and CEO, CEA. “This new terminology and the recommended attributes will help consumers navigate the marketplace to find the TV that best meets their needs.”

The core characteristics that the CEA agreed on include a minimum display resolution of at least 8 million active pixels with at least 3840 pixels horizontal and at least 2160 vertical pixels.

To meet the minimum needs the display will have to have an aspect ratio of at least 16 x 9. Devices meeting the specifications will also be required to have at least one digital input capable of carrying and presenting native 4K format video at 3840 x 2160 resolution without relying on upconverting.

I disagree. Monitors and handheld devices are used close to the face, where it's possible to resolve much higher resolution. Even so, 1920x1080 on a 5" screen is overkill. It's really only useful in that no interpolation or conversion from HD needs to be performed.

No one sits close enough to an 80" TV to see the bump in higher resolution. We've already gone through enough consumer confusion upgrading from analog to digital. We don't need another broadcast standard so quickly.

The next question comes in bandwidth. Broadcast bandwidth is already fixed, so these UltraHD broadcasts would have to be even more compressed than they are now. Higher definition more lossy compression is not an improvement.

I'm a spec junky as much as the next guy, but 4K and UltraHD are a bit unnecessary right now.

" Even so, 1920x1080 on a 5" screen is overkill."

Totally agree its overkill on anything phone related, but not on large screen TV's. They aren't just for video anymore. I use my 42 inch 1080p as a second monitor and its way noticeable, and I can see lines on my 55 inch 1080p. I agree its not "necessary" TV itself isnt "necessary" but a res bump in large screen TV's is long overdue. It was delayed many times over, I am just happy to see it coming.

Picture buying a mid range 32-42 inch screen with 3840x2160 res and plugging your PC into it. NICE!.

Ok, I get that argument. But to be quite honest, you can already get very large format monitors supporting those insane resolutions. Just be prepared to fork over a lot of coin to do so. What you're doing, very few other people do to. And unless you move a chair to sit up close, then the seating position is still the same and the resolved resolution isn't too terrible.

I have a few computers hooked up the the home TVs also, and agree it's a bit grainy, but nothing too bad. I would consider a 4k or higher TV if available. But only if the price is right.

But this UltraHD spec is talking about broadcast. It may be a chicken and egg scenerio, where unless there's a standard no one is going to make a TV that supports it. But at the end of the day, I see this failing miserably just because it's too soon. Dust hasn't even settled on HDTV, a good portion of the US populace hasn't even upgraded yet, and we're talking a new standard.

That's exactly it... until its mainstream the price will be high. Once its standard, it will drop regularly. So this is a good thing.

I have an 80" screen with a 2K (1080p) projector on it, seated with my head 8 feet away. According to graphs indicating resolvability, even I and my too-close-to-giant-screen setup would see no benefit from anything above 2.5K (1440p).

Let's keep in mind that the vast majority of cinemas out there, with their hundred foot screens, are 2K. Only a few are 4K. And audiences generally can't tell the difference.

4K offers no benefit whatsoever to the average consumer, it's just a moneymaking scheme. I mean, yes, it's technologically superior, but it provides an identical experience at a higher cost.

100GB or 128GB quad-layer discs, on the other hand, offer tangible benefits. Less discs in packs mean less space on shelves, or the ability to cram more stuff and bonus features into a single disc.

Plug it in to your PC and tell me how it looks.

My local theater recently switched to a 4k projector. I can assure you I can tell a difference. Not with the picture though, but with flicker. The old one had nasty flicker with white areas. Snow scenes were horrid for example, may as well be in a room with fluorescent lighting on the fritz.

The 4k system bumped frame rate or something because the white areas are now totally flicker free.

As for the picture itself, I used to be able to concentrate (I sit in the 2nd or 3rd row) on pixels and then see them. But unless you are doing that your brain just seamlessly blends it all. When watching a movie you are too busy doing that than to stare at a particular patch of pixels.

Now kids will have a real excuse for sitting too close to the TV: "But mom, I can't fully appreciate the resolution from the couch"
