These days, entertainment is available at our fingertips with the help of devices like tablets, smartphones, laptops, and televisions. Everyone is looking for the best-quality entertainment in the comfort of their personal space. The latest trend in the electronics industry these days is 4k Full HD televisions, especially those with large screens, e.g., 70- to 80-inch TVs. So, what is the fuss about these 4k resolution TVs and why is everyone so eager to buy one for their houses? 4K resolution is one of the highest pixel resolutions to watch a movie and is specially used in theatres and cinematography. 4K is also known as Ultra High Definition (UHD). In such a television, 4000 pixels are horizontally placed to obtain superior quality display. A Full HD TV has a resolution of 1920 x 1080, while an Ultra HD television has that of 4096 x 2160 pixels, which has four times the total pixel count of a Full HD TV. Thus, sharper and brilliant image quality is obtained as the number of pixels is four times the resolution of a full HD TV. Most shows on Netflix and a lot of YouTube videos are of 4K resolution, offering superior-quality entertainment to their viewers.
