As if 3D TV and LED LCD vs. OLED vs. 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. Or if you use its official name, Ultra High Definition (UHD).
UHD is an "umbrella term" that encompasses higher resolutions (more pixels) than HDTV, as well as more realistic color and higher frame rates. 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. Judging from the new TVs shown at CES 2014, manufacturers are tripping over themselves to bring you a new array of 4K compatible products.
But just like 3D and HD before it, 4K has a case of putting the hardware chicken before the software egg. 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.
Still, the shift from 1080p to 4K TV hardware is inevitable. 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.
Confused 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?… Read more
