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 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.
