Which is clearer, 4k or Blu-ray?

4k is clearer. 1080p resolution is 1920* 1080, and 4k display resolution is 4096*2 160.

The whole image can be imagined as a big chessboard, and the resolution is expressed by the number of intersections of all warp and weft. When the display resolution is fixed, the smaller the display screen, the clearer the image. On the contrary, when the display screen size is fixed, the higher the display resolution, the clearer the image.

Extended data:

In most cases, 4K Ultra HD digital movies refer to digital movies with a resolution of 4096×2 160, that is, 4000 pixels in the horizontal direction. Most domestic digital movies are 2K with a resolution of 2048× 1080. Some digital movies are1.3k (1280×1024), while the so-called rural movies are shown at 0.8K( 1024×768).

A real 4K movie is shot by a 4K camera and projected by a 4K projector. Other 4K movies were shot on 35mm film and then converted into 4K digital format. Because the resolution of film film is roughly equal to or slightly better than 4K, the clarity of the film after transcription can be guaranteed. For mainstream home appliance manufacturers, they prefer to manufacture Quad full HD (3840×2 160) equipment, because the display ratio of this resolution standard is 16:9, which is close to the viewing ratio accepted by consumers at present.
