Other shooting resolutions are also employed in the pro realm, depending on the camera.įour resolutions compared: standard definition full high definition and the two kinds of ultra high definition (Quad HD and 4Kx2K). It also falls under the umbrella of 4K/UHD.

This resolution was originally known as "Quad HD," and it's used by basically every 4K TV.Īnother resolution, known as 4Kx2K (4,096x2,160 pixels), is used by some projectors and many professional cameras.

When used in a home context, 4K/UHD means the TV's screen has a minimum resolution of 3,840 pixels wide and 2,160 pixels high, making it the equivalent to two 1080p screens in height and two in length. With the arrival of 4K there are four main resolution standards for use in the home: standard definition (480p/540p), high definition (720p), full high definition (1080i/p) and ultra high definition (2160p). The latest in a line of broadcast and media resolutions, 4K is due to replace 1080p as the highest-resolution signal available for in-home movies and television.
We at CNET say "4K" instead of "UHD" almost exclusively, and our readers and Google strongly agree. In practice, you will often see UHD used interchangeably with 4K, whether describing TVs, source devices, accessories or content. This is the term now used by most other TV manufacturers too, who seem interested in covering all the buzzword bases at the expense of brevity. The CEA's name lasted less than a day, as Sony then announced it was going to call the technology "4K Ultra High Definition".
In August 2012, the Consumer Electronics Association introduced the term Ultra High Definition, partly defined as resolutions of "at least 3,840x2,160 pixels". This year 4K TVs will replace high-end 1080p models as the best-performing LED LCD-based sets on the market - although the reason they're better will have nothing to do with resolution.Ĭonfused again? Don't worry, we'll walk you through, starting with the question: So what is 4K anyway, and what makes it different from high definition? What's in a name? '4K' versus 'UHD' Still, the shift from 1080p to 4K TV hardware is inevitable. About 15 months after 4K TVs first appeared on the market, there's little consumer 4K content available: no TV channels or Blu-ray discs, just a few specialized video players, YouTube and other clips of varying quality, and promises of streaming video.

Judging from the new TVs shown at CES 2014, manufacturers are tripping over themselves to bring you a new array of 4K compatible products.īut just like 3D and HD before it, 4K has a case of putting the hardware chicken before the software egg. Today and this year, pretty much the only one of those improvements available in new TVs and content is 4K resolution, so that's what we'll talk about here. UHD is an "umbrella term" that encompasses higher resolutions (more pixels) than HDTV, as well as more realistic color and higher frame rates. Or if you use its official name, Ultra High Definition (UHD). plasma and 120Hz and the Soap Opera Effect weren't confusing enough, in the last year we have seen the rise of a new HDTV technology called 4K.
