While 4K Ultra HD televisions are right here, content is still not there.
4K, also known as Ultra HD (UHD), just like its former brother HD was a few years ago, has become all anyone in the television business is talking about. 4K Ultra HD offers four times the resolution of traditional HD displays. The answer to this improvement has something to do with the amount of pixels a 4K TV contains. While traditional HD has 1920 columns and 1080 rows of pixels, Ultra HD has a total resolution of 3840 pixels by 2160. However, when you try to buy a new television and you are offered to a 4K TV you realize that there's a lack of 4K content out there.
