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. Want to enjoy and handle high quality 4K videos? Here’s what you need to know about them.

Ultra HD Blu-Ray

Can you play 4K Ultra HD Blu-ray discs on a regular Blu-Ray player?

Primarily because 4K disc image files are encoded with HEVC not the MPEG 4 AVC of standard Blu-ray. You need an Ultra HD Blu-ray player to play Ultra HD Blu-ray discs. If you put an Ultra HD Blu-ray disc in a non-Ultra HD Blu-ray player, it won’t work. It’s an important distinction, and cause of this we can see a lot of potential for frustrated users wondering why they can’t watch their new movies.

This means you need a new player. Plug and Play UHD friendly drives BW-16D1HT and BC-12D2HT are highly recommended.
