What does 4k Ultra HD mean

What is 4K What does 4K mean?

Ultra HD stands for Ultra high definition and is the successor to the high-resolution full HD standard. The resolution at 4K is round four times as high as Full HD.

Televisions, monitors or projectors that support the new Ultra HD standard therefore provide a much sharper picture than previous televisions. The big advantage is that the distance to the television hardly needs to be increased, even with oversized sizes (over 60 inches / 150 cm screen diagonal).

Even if you are sitting directly in front of the television, pixels are barely recognizable.

Difference between Ultra HD and 4K

Ultra HD is that format, while 4K is a term for a specific resolution. In addition to 4K, there is also 8K (also called Super Hi-Vision), which has a resolution of 16x as finely as Full HD.

The confusion with Ultra HD and 4K comes from the fact that 4K has been used to denote the high definition video format for a number of years. The Consumer Electronics Association or the International Telecommunication Union (ITU) did not have the official name until mid-October 2012 Ultra HD set.

Ultra HD and 4K are two names for the same format or the same resolution. However, the CEA has defined standards that must be met if a manufacturer is using the designation Ultra HD wants to distinguish.

In addition to a minimum resolution of 8 million pixels (4x as many pixels as current Full HD TVs) must have 4K TVs over connections that can also transmit corresponding 4K content. These include HDMI 2.0 and DisplayPort 1.2.

Incidentally, Sony has decided to keep the designation 4K. Sony televisions therefore now bear the name 4K Ultra HD.
