Blu-ray is not 1080P, the definitions of the two are not the same.
Blu-ray refers to an optical disc storage technology that uses blue lasers with shorter wavelengths to read and write data to form a Blu-ray disc, and then 1080P high-definition video can be stored in the Blu-ray disc.
1080P is a standard for video definition, which is used to express the resolution of the video.
It can only be said that the two are related, but not the same concept.
