4K resolution officially named Ultra High-Definition

By , source: Electronista

The Consumer Electronics Association (CEA) has announced that the official name for the resolution that was previously known as 4K-2K, is Ultra High-Definition, or UltraHD. The introduction of the official definition comes forth from the fact that the International Telecommunication Union (ITU) has already started developing a standard for Ultra High Definition Televisions (UDHTVs) with a resolution of 3840x2160 or even 7680x4320 pixels.

Ultra High Definition is a resolution of 3840x2160 pixels, four times that of the Full HD standard. The current 16:9 aspect ratio, is retained with the new format, meaning it's the level of detail that will increase significantly over the coming years. The CEA standard means that Ultra HD televisions will have at least one digital input capable of processing the resolution, without requiring upscaling. In the past, the first HD-ready and Full HD televisions were models that were capable of upscaling video to the respective resolution.

Most manufacturers are likely to keep the Ultra High-Definition naming. As of yet, only Sony has announced to use 4K Ultra High Definition (4K UHD), instead of Ultra HD, as it would be clearer to consumers, given the fact that UHD can be both 4K and 8K.

This 84-inch LG UD 84LM9600 already supports Ultra HD. 

4K UHD and 8K UHD respectively 4x and 16x more pixels than Full HD.
