What is a 4K Ultra HD Blu-ray Disc?

The Ultra HD Blu-ray player is great for streaming content via your favorite apps like Netflix, Hulu, and Prime Video. If you really want to get the most out of your Ultra HD Blu-ray player, you will need a 4K Ultra HD Blu-ray disc.

4K Blu-ray

Many new and recent movies are available or coming soon to 4K Ultra HD Blu-ray, just make sure you are buying the right thing. There are some Blu-ray discs available that say "Mastered in 4K" on the box, but these are NOT 4K Ultra HD Blu-ray Discs. These are standard Blu-ray discs that have been scaled down from a 4K picture. 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. Normal Blu-ray discs look great, but the maximum resolution is 1920 X 1080. A 4K Ultra HD Blu-ray disc has a resolution of 3840 X 2160. That's 4 times the amount of pixels. Many describe an Ultra HD image as feeling like looking through a window, rather than watching TV.
