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 guess if there is one positive side to 4k (UHD) it is that there really isn't much/any need for anything after that for home use.


i heard that from people when 1080 first came out..

LOL

Yes but with 4k (UHD?) you have to be 5 feet away from an 80 inch screen, or 3 feet away from a 60 inch screen to notice based on this article: http://carltonbale.com/does-4k-resolution-matter/

With that said I find the calibration of that diagram pretty questionable. Based on that you have to be 15 feet on a 50" TV before the "full benefit" of 480p is visible. I think for many people these are living room distances and there is a huge difference between 480p and HD even if your eye sight is wonky.

I personally don't think I would notice much difference between 1080p an 4k on my 50" TV but if I replace it with an 80" TV I might or start using one as a PC monitor I might.

If TV manufacturers need something else to set a goal for instead of racing to the bottom in pricing I say go for it. Maybe by the time my kid is old enough to play games he will have a couple of 80" 4k TV's in his game room for his friends to play photo realistic games on. This doesn't serve much purpose for average use but it moves us a little closer to that.

There's a big difference, but I think the benefit of going to a 1080p was exaggerated for most people by all the other changes that were made at the same time. You're changing a lot of variables when you're going from SDTV over analog component cables to a tube TV vs 1080p signal over digital cabling to a 1080p TV.

Try watching a 1080p Youtube video (particularly an animated one that was rendered at hi res like http://www.youtube.com/watch?v=XSGBVzeBUbk) at full resolution, and then change your monitor's resolution to VGA (640x480). The difference you'll see just from the resolution increase isn't nearly as large as you see going from something like SDTV sports to the HD version.

4k is going to be pretty underwhelming, IMO. People will limited on the size of TVs they can use by their room, and the benefit from a 4k display on a 40-50" TV won't be a huge leap from 1080p without other features.
