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.

At least 16 x 9

What does that even mean? "At least" in which direction?
So 3840x2160 is UHD, but only one of 3840x2400 and 5040x2160 is? And in that case, which one?

I think the last line has a typo. It should be 3840x2160 NOT 2840x2160.

I think it's safe to assume movies aren't going to go back to narrow aspect ratios; so if 16:9 is the minimum 5040x2160 would count but 3840x2400 wouldn't.

But the allowed 3840x2160 is contained within 3840x2400.
How can something bigger than UHD not meet the minimum requirements for UHD?

Because they define both minimum horizontal, vertical, and aspect ratios. Starting at the minimum for all three, you can't only increase only height without dropping below the minimum aspect ratio.

Its mean you have to buy a new TV yet again. HD->HD3D->UHD

I think the answer is simple. The term "at least" is meaningless in the context of aspect ratio. It's not a "more or less" characteristic like for instance battery life where more is clearly always better. Which aspect ratio is better depends on what the display is used for, and even when that's defined, the answer is highly subjective. For this reason, people have argued and will continue to argue until blue in the face about the "best" aspect ratio.

This is probably to cover the case of the 4K Digital Cinema standard which is 4096 x 2160. Such a screen would still be covered under the rules to be allowed to be called UHD. My guess (purely guess) is that since the 4K Digital Cinema standard has been around for a few years these guys wanted their UHD definition to be "backwards compatible" and cover that older standard too.
