The resolution Ultra-HD / 4K

Schematical comparison of Full-HD and Ultra-HD

Schematical comparison of Full-HD and Ultra-HD

What offers Ultra-HD / 4K?

Ultra-HD / 4K (UHD-1) offers with its 3840 x 2160 pixels a four times higher resolution than Full-HD and a twenty times higher resolution than SD. The challenge is, there is a naming confusion in the area of entertainment electronics as well as at smartphone & Co. and seemingly, nobody knows what is actually what. Following table may help:

 RESOLUTIONS 

Why this mixup of terminologies?

Ultra-HD or 4K or even 4K Ultra-HD? The current user gets confused mainly because manufacturers juggle with the names and partly, they use the same label for articles with different resolutions. Colloquial, resolutions with about 4000 pixels in the horizontal are called „4K“. More exactly it has to be distinguished between UHD and DCI resolution: UHD has 3840 x 2160 pixels like mentioned above. DCI (Digital Cinema Initiatives) is the 4K format used by digital cinemas and has a resolution of regularly 4096 x 2160 pixels. In technical view, 4K and UHD are different!

The official Ultra-HD logo (green), and manufacturer-own label creations

However, in everyday life the name „4K Ultra-HD“ is often used. And even if the CEA already in 2012 decided the name Ultra-HD has to replace the name 4K preferred until then, there is still disagreement about the naming. Like mentioned above, mainly manufacturers mix names together for promotion proposes.

The label QFHD is also used sometimes. Don't get confused! For example, a display with a resolution of 3860 x 2160 is called QFHD or 2160p/i. QFHD stands for Quad Full High Definition and the „quad“ relates to the four times higher resolution than Full HD. QFHD is just another name for Ultra-HD. .
