In the respect of television and consumer media, 3840 × 2160 (4K UHD) is the main 4K standard, while the movie projection industry uses 4096 × 2160 (DCI 4K).

It specified the standardized 2K and 4K container formats for digital cinema production, with resolutions of 2048 × 1080 and 4096 × 2160 respectively.

Blu-ray VS 4K Streaming

Blu-ray, the abbreviation of Blu-ray Disc (BD), is a digital optical disc storage format. As the next generation of DVD, Blu-ray owns a more powerful function of storing high-quality videos, audio and other documents. However, until now, DVD has not been completely replaced by Blu-ray restrained by the need for better equipment.

4K Streaming means the 4K quality video playing in the streaming platform such as Netflix. It is famous for its convenience and high-quality videos.

what is 4k uhd

Blu-ray: 1920×1080

4K: 3840×2160

4K Streaming: 3840×2160

The resolution of 4K is twice that of Blu-ray, which could provide a better watching experience. With HDR technology, the whole video will overpass BD in definition, contrast, brightness and color. The usual markers, such as the definition and texture on hair, skin, clothing and buildings are all very impressive, especially for a large screen. This is the reason why many companies choose to invest in UHD.

When comparing 4K Streaming with Blu-ray, the former has a higher resolution. However, due to the restriction of higher compression and low bitrates, which poses a challenge to the picture resolution, 4K Streaming is inferior to the performance of Blu-ray especially in the darkness.

Sound Quality

For video lovers, the picture quality is as significant as sound quality. They will post high demands not only in the picture but also be critical about hearing the content. No matter you use Blu-ray or 4K, you could enjoy uncompressed Dolby TrueHD or DTS HD Master Audio, typically in 5.1 but regularly in 7.1. Besides, both equipment support Dolby Atmos, which enables to build a more immersive environment to give a better experience. Frankly speaking, it is difficult for us to be aware of the nuance between Blu-ray and 4K in sound quality.

When it comes to the sound quality, 4K streaming doesn’t own any similar equipment which leads to much less performance in the field of sound quality.

Conclusion: 4K≥Blu-ray>4K Streaming


In the streaming age, it is much more convenient for us to search for plenty of resources on the Internet. As long as you click the poster or keywords, your wanted video will turn up at once. Time and space will limit the watching experience all available at the touch of a button. However, 4K Streaming can’t ensure stable service to every user, and the number of people online and even weather will exert effects on the watching experience.

Although disc can’t provide the same convenience, Blu-ray and 4K UHD embody more content more than the main feature, such as behind the scenes and directors’ interviews. What’s more, the special version of 4K UHD will contain the related items including the movie posters, directors’ motes and other small objects connecting with the movie. Just like a package of gifts, these items not only add a sense of amusement but also have great value in the collection.

While 4K discs are around £20 to £25 each without considering the cost of the player. The first UHD Blu-ray player to enter our test rooms costs £600.
