10 Important Difference Between Blu-Ray and 4K Blu-Ray(Tabular Form)

Difference between Blu-Ray and 4K Blu-Ray

To help you better grasp the difference between Blu-Ray and 4K Blu-Ray, we’ve put up a little explanation below.

We’ve all heard of 4k Blu-Ray, which are the successors to Blu-Rays, but what exactly is 4K Blu-Ray? And, if they’ve been superseded, why are Blu-Ray discs still in use? Is Blu-Ray still superior in some ways? We’ll go over that in more detail in the next sections.

What Is Blu-Ray?

Blu-ray is a digital disc storage format, similar to CD and DVD, that allows you to store and play large amounts of data in high-definition.

It was primarily designed to store high-definition videos, which were previously impossible to store using DVD technology.

The name “Blu-ray” stems from the fact that it reads the disc using a blue laser, which allows for higher data density than DVD, which uses a red laser. It is recommended and produced for high-definition(HD) videos.

The storage capacity of Blu-ray discs is 25GB of data in single layer. It is obviously larger than previous disk formats.

Blu-ray discs are the same size as CDs and DVDs before them, but they can’t be played on standard CD or DVD players; instead, you’ll need a Blu-ray disc drive. However, the top Blu-ray players can also play CDs and DVDs, providing some backwards compatibility.

What Is 4K Blu-Ray?

Ultra HD Blu-Ray, or 4K Ultra HD, is another name for 4K Blu-Ray. 4K Blu-Rays are simply Blu-Rays that output movies and TV shows in 4K quality rather than the conventional HD resolution used by standard Blu-Rays.

A 4K Ultra HD Blu-Ray disc has a substantially larger capacity than a conventional Blu-ray disc, allowing it to store Ultra HD movies. The resolution of 4K Blu-ray is 3840 x 2160 pixels.

4K Blu-Ray has double the horizontal and vertical resolution of 1080P Blu-Ray. In the battle of 4K Blu-Ray vs Blu-ray(1080P), 4K must be the winner in terms of visual pleasure.

After comparing the difference between Blu-Ray and 4K Blu -Ray specification we came to the decision that they are quite different from one another in terms of storage, capacity and picture quality.

Blu-Ray and 4K Blu-Ray has a video resolution of 1080×1920 and 3840×2160 respectively. 4K also support HDR in Dolby Vision.

While Ultra HD formats are the future of the high-resolution market, they will not make your HD Blu-Ray collections outdated.
