Question: are 4k and blu ray the same?
Answer: They offer a wider range of color, but it is not the same as a 4k Ultra HD Image. A 4K Ultra HD Blu-ray disc has a much higher capacity than a standard Blu-ray disc which allows it to store a movie with Ultra HD resolution. ... A 4K Ultra HD Blu-ray disc has a resolution of 3840 X 2160. That's 4 times the amount of pixels.
