4K Ultra HD Blu-ray

4K Ultra HD Blu-ray is a new format. I started buying Ultra HD Blu-rays since 2017. There is a link called Films I have on Ultra HD Blu-ray in the UK if you would really like to see which Ultra HD Blu-rays I have. I currently have 11 UK Ultra HD Blu-rays. (5 titles from Sony Pictures Home Entertainment, 3 titles from 20th Century Fox Home Entertainment, 2 titles from Lionsgate UK and 1 title from Warner Home Entertainment) On March 1, 2016, 24 Ultra HD Blu-rays were released in the United States and Canada. 20th Century Fox Home Entertainment released ten launch titles, Lionsgate and Warner Home Entertainment released four titles and Sony Pictures Home Entertainment released six titles. So that makes a total of 24 Ultra HD Blu-rays.
