Which is seldom portrayed exactly on television
4K televisions get their name from their resolution, which is around 4,000 pixels wide. Usually it is 3,840 x 2,160 pixels. This resolution is also known as Ultra High Definition (UHD). It is the direct successor to Full HDTV and, with over eight million pixels, has four times as many as its predecessor. Like this one, TVs with UHD resolution have an aspect ratio of 16: 9. The term 4K originally comes from the cinema sector, where a resolution of 4,096 x 2,160 pixels is used. This is why the term 4K2K is also used. The aspect ratio of 4K is originally 17: 9, with some pixels being cut away for the 21: 9 cinema format. However, 4K and Ultra HD are largely used synonymously today.
UHD resolution provides razor-sharp images
The quadrupling of the resolution from Full-HD-capable to UHD represents a significant improvement for the picture quality. Due to the higher number of pixels, television pictures can be displayed in even more detail and the pictures become significantly more sharp. This makes you look even more realistic. In addition, the individual pixels are much smaller for the same screen size. On a 55-inch HD television, one pixel is around one millimeter wide, and on a 4K television it is only half that. As a result, the television picture is still clear and clear even with a smaller distance between the viewer and the screen. The individual pixels cannot be seen. Large 4K televisions are therefore more suitable for small living rooms. The distance can be reduced to two meters, which allows the viewer to immerse himself more intensively in the action. Disadvantages of a 4K TV: It consumes more power and when the seat is wide, the difference to Full HD is hardly noticeable.
4K resolution so far rarely in the TV program
Of course, the picture that 4K televisions display also depends on the program they are receiving. Most TV channels now broadcast in full HD quality. 4K TVs cannot reach their full potential with this signal. However, the devices extrapolate the image to its resolution. They do not show more details, but the picture on them is better than HDTV sets. It looks cleaner and clearer. Occasionally, however, some broadcasters are already broadcasting productions in Ultra HD. Streaming providers such as Netflix or Amazon Prime are also increasingly offering series and feature films with the appropriate resolution for 4K televisions.
