— screens conditionally related to the Ultra HD 4K standard. The standard frame size in this standard is 3840x2160; smartphone displays related to this format usually have the same resolution. However, there are still very few such devices. This is mainly due to the fact that Ultra HD displays are very expensive — both by themselves and because of the high performance requirements of a smartphone; and a decent level of detail can be achieved at more modest resolutions.
