Understanding the Difference Between 4K and 8K

What is 4K Resolution?

Also dubbed as Ultra HD (UHD), 4K is a popular display resolution nowadays. People know that resolution is just the number of pixels in the format of length x width that a device has. 4K is nothing but a horizontal display resolution of almost 4,000 pixels. The DCI (Digital Cinema Initiatives), a branch of motion picture studios that develops standards for digital cinema, describes 4K video resolution as 4096 x 2160.

Movie projection sector also employs this DCI standard. On the other hand, monitors, normally dubbed as 4K, comes with a 3840 x 2160 resolution. The same goes in the case of consumer media and 8K vs 4K TV. Modern GPUs show support for 4K/Ultra HD (UHD) output, although a quite superior graphics processor is needed to play games in 4K. This is the reason why most users prefer running at 1080p resolution.

What is 8K Resolution?

Rationally 8K will be 2 times the resolution of 4K, but fascinatingly, that is not the case. In this battle of 8K TV vs 4K, 8K is termed as UHD-2. Currently, it is the highest UHDTV or ultra high definition television resolution. It defines the vertical resolution of 4320pixels and horizontal resolution of 7,680 pixels. Hence, it forms the entire picture dimensions of 7680 × 4320. 8K resolution is in fact, 4 times the pixels of 4K and 16 times the pixels of HD. Therefore, 8K equates to 33 million or 7,680 × 4,320 pixels.

In simple words, when four 4K TVs are positioned in a four-by-four group, that is a lot of pixels. That is why 8K can indisputably be noticed when on larger displays or up close. Nowadays, companies are beginning to declare the obtainability of their 8K device. Earlier, there was a bit 8K Ultra HD resolution movies to watch at home. But eventually this situation is altering. A few years back, Vimeo (the video-streaming site) added support for 8K, but now it already has over 6,000 videos hosted in 8K.

4K VS 8K: What’s The Difference Between 4K and 8K?

In this 4K TV vs 8K TV resolutions, there are some perceptible technological differences. They are very different when it comes to frame rate, resolution, broadcasting, audio channel, and viewing angle. Below are some points that cover basic difference between 4K and 8K video resolution to help you better understand. Have a look.

Frame Rate

Frame rate is nothing but the number of images or frames that are shown per second in a monitor. It is related closely to video quality and broadly employed in synchronizing pictures and audio. It is claimed that the higher the frame rate is, the more exceptional the video quality of the output will be. 8K resolutions supports up to 120 Hz of progressive frame rate as compared to 4K that supports only at 50 to 60 frames per second.

Resolution

A vertical resolution of 4320 pixels and a horizontal resolution of 7680 pixels describes 8K UHD resolution. On the flip side, a vertical resolution of 2160 and a horizontal resolution of 3840 describes 4K UHD. Hence, the 8K UHD has two times the vertical and horizontal resolution of the 4K UHD. Normally, the 4K UHD has 8.3 megapixels, while the 8K UHD has a humongous 33.2 megapixels.

Viewing Angle

When it comes to viewing angle, it refers to the maximum number of angle that users can see with tolerable visual performance on a display device or a monitor. It is an essential feature that effects users experience of viewing. When it comes to viewing angle, 8K support horizontal viewing angle of 100 degrees while 4K provides a viewing angle of 55 degrees. 8K permits for more visual angles as compared to 4K.

Audio Channel

4K and 8K are very different when it comes to supporting audio channels. 8K shows support for 22.2 audio channel, while 4K shows support for 5.1 audio channel. Apart from this, while using 8K, user might experience the 3D super stereo.

Broadcasting

H.265 (also known as High-Efficiency Video Coding) must permit 4K streaming content with a 20 to 30 Mbit/s of bandwidth. Earlier, the capability of a transmission network to transmit 8K resolution was limited by internet speeds and relied on satellite broadcast to transfer the high data rates. This requirement will seemingly drive the acceptance of standards for video compression and place distinguished pressure in the near future on physical communication networks.

In addition to this, as per a latest research, Host Broadcasting Services earlier claimed that minimum 75% of the broadcast limit on every match might come from 4K cameras (wrapping almost every main angle), with instant replays. Earlier, FIFA World Cup was the first event in which all matches were shot in 4K. Experimental transmissions of the 8K resolution were experimented with the 2012 Summer Olympics.

Below is the table that tells the differences between 4K and 8K resolutions in short. Have a look:

Step 8: Next, click Start and wait for the process to end.

Conclusion

In the end, it can be said that 8K display resolution is the heir to 4K resolution and is surely far better. Both 8K and 4K, the two Ultra HD formats, can offer excellent visual sense and super vivid image. It is, on the other hand, a luxury for common people to buy a 4K or 8K UHD TV.

It is also hard to get different contents which are entirely compatible with such high-tech products. Hence, to deal with this situation, users can convert normal content to 4K and 8K resolution.
