Dvd Vs Blu Ray Resolution


As technology continues to advance, our movie watching experience has gone through various changes. The video cassettes were replaced by DVDs and later, Blu-rays made an entry. Blu-ray players came with an improved resolution of 1080p compared to the 480p resolution of DVDs. But even now, many people wonder whether Blu-ray is worth the upgrade from DVDs. In this article, we’ll compare DVD vs Blu-ray resolution and decide which is the better option for your viewing experience.

What is DVD Resolution?

To start with, DVD stands for “Digital Versatile Disc.” They are storage devices that store movies or any other content in a digital format. DVDs have an MPEG-2 video codec which streams videos with a resolution of 720 x 480 pixels. This is also known as “Standard Definition” or SD in short. In simpler words, the video quality of DVDs can be compared to the quality of a standard TV of the 90s.

What is Blu-Ray Resolution?

Blu-ray discs use a blue-laser technology resulting in a higher storage capacity. This means more information can be stored in a smaller space. It also allows for a wider range of audio and video options. The high-definition (HD) resolution that Blu-rays are known for is called 1080p. This means that the image quality of Blu-rays has approximately six times more detail than DVDs, with a resolution of 1920 x 1080 pixels.

DVD Vs Blu Ray Resolution: Comparison

Now that we know the basics of DVD and Blu-ray resolution, let’s dive into a deeper comparison between the two.

Image Quality

Image quality is a crucial factor in deciding which option to choose. DVDs can display an acceptable picture quality, but it’s inferior to anything HD. The primary reason is the resolution. DVDs have a maximum resolution of 720 x 480 pixels which gives a pixel density of 345,600 pixels. On the other hand, Blu-rays offer a resolution of 1920 x 1080 pixels which results in a pixel density of 2,073,600 pixels. This means that the density of pixels in Blu-ray is nearly six times more than that in DVDs. Thus, Blu-rays have a much better image sharpness and clarity than DVDs.

Sound Quality

Along with video quality, sound quality also plays an essential role in movie watching. The audio codec used for DVDs is Dolby Digital and DTS. Both of them are compressing techniques used to enhance the audio quality. But, these compressing techniques only support 5.1 surround sound. On the other hand, Blu-rays support a resolution of up to 7.1 surround sound which gives the viewer a more immersive experience. Along with the resolution, the compression techniques used in Blu-rays are also better which maintain the audio quality even in the highest volume. Thus, Blu-rays have a significant advantage over DVDs when it comes to sound quality.


Blu-rays have a significant advantage in terms of image and sound quality over DVDs. But, there is also a considerable difference in the cost between the two. Firstly, the equipment required for playing Blu-rays is much more expensive than that of DVDs. A basic DVD player costs as low as $20, whereas a Blu-ray player starts from around $50. Moreover, the cost of a Blu-ray disc is also much higher than that of a DVD. A Blu-ray disc can cost up to $30 per movie, whereas a DVD can cost around $5 to $10. Therefore, Blu-rays are not affordable for everyone.


Blu-rays have a vast advantage in terms of image and sound quality over DVDs. The resolution of a Blu-ray is six times higher than that of a DVD. Moreover, the audio quality in Blu-rays is also far superior to that of DVDs. However, the cost of the equipment required to play Blu-rays and the price of the discs themselves are much higher than that of DVDs. Therefore, deciding between the two depends on the person’s budget and preferences. If someone prefers better image and sound quality and is willing to pay the cost, they can opt for Blu-rays. On the other hand, those who are comfortable with acceptable quality and want to save money can still enjoy watching DVDs.
