4K is the next big thing in display technology and it is already coming to big screen living room TV near you.
4K is a specific display resolution of 4096 x 2160 while Ultra HD TVs have a resolution that is slightly lower at 3840 x 2160, which is exactly 4 times high than the current Full HD resolution. In other words, it is all the same, just lots more pixels.
Do you need an Ultra HD TV? Well, technically speaking, the more pixels that make up an image, the more detail you see, hence the smoother the appearance of curved and diagonal lines. Ultra HD takes all this to a higher level and is already making inroads into the world of digital cinema. While 4K will makes the subtle nuances in pictures easier to appreciate, there really isn’t a need to upgrade your HDTV to an Ultra HD one unless you’re a home theater enthusiast and love having the latest TV technology in your home.
