Blu-ray is a media format that offers more space and quality than a DVD. It was developed in the mid-1990s as a successor to DVD. The two main advantages of Blu-ray are the large storage capacity of the discs and the Full HD picture quality. Blu-ray players can also play your entire collection of other types of discs, both CDs and DVDs.
Blu-ray is better picture
With a Blu-ray player and Blu-ray discs, you get the best picture quality on your HD TV. Better than HD broadcasts on TV or via a streaming service. The resolution of Blu-ray is as much as seven times higher than DVD. Roughly the same difference as previously between VHS and DVD. The smallest details such as beard hairs on faces and the patterns and fabrics of clothing are reproduced with razor sharpness with Blu-ray. Color reproduction with Blu-ray is also much more accurate, making images appear more vivid and realistic.
Blu-ray is better sound
Blu-ray builds on the surround-sound capabilities introduced with DVD. With Blu-ray's advanced audio options and new surround-sound formats like Dolby TrueHD and DTS-HD Master Audio, you get a sound that is potentially virtually identical to the sound in the theater.
