What is 4K?

4K resolution or 4K denotes a display device or content with horizontal resolution on the order of 4,000 pixels. A "display" could be the screen on a TV, iPad or laptop.  The Consumer Electronics Association (CEA) defines an Ultra HD television as one that displays at least 8 million active pixels, with a lower resolution boundary of at least 3,840 by 2,160. There are multiple varieties of 4K digital content ranging from 3,840 by 2,160 to 4,096 by 3,112. However, the 3,840 by 2,160 resolution is the most consistent number.

Ultra High Definition (UHD)

Basically, with more pixels, the images look sharper and more realistic. However, the individual pixels make the images look blocky and less natural. Hence, it is preferred to have displays with a higher resolution, and 4K is a very high resolution. That's why it's sometimes also known as "Ultra High Definition". Collectively, the format was originally known as 4K, and while the CEA officially changed its designation to Ultra HD, the 4K tag is more known and both terms are effectively interchangeable.
