4K (UHD) Explained

What is 4K (UHD)?

4K (UHD) is the name of a resolution that is 4 times sharper than Full HD. 4K has a minimum sharpness of 3840 by 2160 pixels, which is more than 8 million pixels in total. This ensures a razor-sharp display of films, photos, and games. On this page, we explain what 4K is and what the advantage is.

UHD

A UHD image contains more than 8 million pixels, while a Full HD image has 2 million pixels. This makes the UHD resolution 4 times sharper. You mainly see the difference in sharpness on screens from a size of 40 inches. To view UHD images, both the TV and source must support this resolution. This can be a UHD Blu-ray player or game console, but video services such as YouTube and Netflix also increasingly offer UHD videos.

4K

The 4K resolution is an image standard for cinemas and consists of 4,096 x 2,160 pixels. The difference with UHD is that the row of horizontal pixels is wider. This is because the cinema screen is proportionally wider than the screen of a TV. Yet 4K is now intertwined with the UHD of the TV industry. During your search for a TV, you can assume that 4K and UHD mean the same.

8K

The successor to the 4K resolution is 8K. This resolution is 4 times sharper than 4K, which means that an 8K screen consists of approximately 33 million pixels. Although little footage is available in 8K yet, 8K TVs are already available. These televisions use a technique called upscaling, which makes the TV sharper images of lower resolution.
