8K resolution is a hot word in recent years, how much do you know about it? Next, let’s take a look.
What is 8K resolution
Before we talk about what is 8K resolution, let’s talk about what resolution is. Resolution is the number of pixels that make up an image on a display screen, think of the number of pixels as points of light; the higher the pixels, the clearer our pictures and videos will be.
So what is the resolution of 8K? The name 8k refers to the number of pixels on the horizontal edge of an image, which is about 8000, four times the resolution of 4K; 8K resolution it has an amazing 7680×4320 pixels, which is equivalent to 33 million pixels.
8K vs. 4K Resolution Differences
4K total pixels are 3840×2160 = 8294400
8K total pixels are 7680×4320 = 33177600
4K resolution has 8 megapixels, while 8K has 33 megapixels, which is about 4 times more than 4K.
4K is Ultra High Definition (UHD) used in modern TVs, cameras, LED displays, and video streaming. 8K is known as 8K Ultra High Definition, UHD-2, and Ultra High Definition, and is used in high-end televisions, cameras, the movie projection industry, gaming, and some high-end LED display applications.
Although 8K and 4K provide us with great convenience, there are also very significant differences between these two resolutions when considering their use in different scenarios.
- Resolution: 4K contains 4096×2160 pixels for movie theaters; 3840×2160 pixels for use with TVs. 8K provides the movie theater and TV industry with an ultra-high pixel count of 7680×4230, so we get more pixels and higher quality than 4K gives us when watching an 8K video or TV.
- Frame Rate: 4K resolution can be used at 50-60fps while 8K is 120fps (frames per second). The higher the frame rate the smoother the rate of movement of the video, the less blurring of the video, giving the viewer a better experience.
- Audio Channels: 4K has 5.1 audio channels and 8K resolution has 22.1 audio channels, which is four times more than 4K, which means more audio channels for the viewer to feel more realistic and immersive.
- Viewing angle: 4K resolution allows viewers to enjoy a 140-170 degree viewing angle, while 8K resolution allows viewers to enjoy a 160-170 degree viewing angle, which means viewers can see more clearly when watching 8K video or TV closer to the screen.
- To summarize：The higher the pixels, the better the results will be when used on a video player. However, more pixels means more resolution, which means it takes up more hard disk space, and we won’t be able to watch this high magnification content as well on smaller devices.
All things considered, 8K is the best resolution available today, and it’s there to provide a higher level of detail and clarity for those looking for an enhanced sense of the visual visual experience, but there are also factors that must be considered such as processing power, the specific requirements of a broadband project, and more.
Do we need 8K？
Advantages of 8K resolution
The arrival of 8K resolution also brings many benefits to our lives, with more freedom to shoot and edit. It also enhances our medical care, with ultra-high resolution allowing for highly detailed examination of tissues at the cellular level for use in pathology, surgical planning, and more.
Some of the current problems with 8K resolution
In addition to a 8k screen, 8k video requires high speed channels to access the screen. There are as many as four times as many pixels as 4K, and each pixel carries different information, which means that 8K video takes up a lot of broadband. So that means you’ll need new cables before you can have an 8K TV, and the top certified HDMI Premium High Speed cables are rated at up to 18 Gbps.
To meet the 8K requirements, you’ll need to wait for the HDMI Forum to officially certify some of the Ultra HDMI cables, or look for cables that are compliant with the standard and have a maximum bandwidth of 48 Gbps. monoprice only has two 8K HDMI cables available. Monoprice currently has only two 8K HDMI cables.
The resolution of 8K is very high, and we can see better material and videos than before, but due to the limited content available below 8K resolution, there are a lot of creators who intend to upload videos in 4K quality, and even if we have a TV with 8K resolution we can only see videos in 4K.
While this is still a new technology, one day it will be popularized and become the norm in our lives, so there is no harm in being ready to adopt 8K now.
What 8K brings to our experience
8K brings a lot of new experiences into our lives as well. It offers outstanding detail and clarity, ideal for professional-grade projects, and the added pixels of 8K ensure that every image and video is extremely sharp and detailed. 8K also offers greater editing flexibility, allowing videos to be zoomed in, cropped, and edited as much as you like without loss of quality, which provides unmatched flexibility in post-production and allows for even greater creative and innovative adjustments.
8K’s cameras also offer Versatility While high-resolution cameras have traditionally been larger and bulkier, there are now more compact 8K cameras available. Ideal for video blogging, filming events, and professional use, these cameras are compact, making high-resolution filming more flexible and convenient.
Where to find 8K in everyday life
8K is actually already in our daily lives, in fact, many of us are already enjoying them without even realizing it. It’s not just found on televisions and cameras. Surveillance for example has 8k resolution to ensure safe traffic monitoring and smart city infrastructure provides a new dimension. There are also virtual production video walls for shooting IMAX movies that use 8K resolution.
In gaming, it may support 8K rendering by the end of the 2020s, giving gamers an experience like no other. 8k is also making even more inroads in the sciences, where fields like astronomy and microscopy can utilize 8K resolution to unveil new insights from ultra-high-resolution images.
There are also displays in shopping malls, native images using dozens of LED displays stitched together, and more. Of course, the popularity of 8K is not limited to these areas, and we should always be prepared for 8K to bring us higher quality.
What is the significance of 8K today?
The traditional pixel of our TV is 1080P, when we upgraded from 1080P to 4K, it caused a huge sensation, now we upgrade from 4K to 8K, it also caused a global sensation. The fact that we are moving away from 8K TV sets also proves the progress of human technology, of course, in the future there may be 12K or 16K and so on, which proves that the standard of living of human beings is constantly improving.
Summarize
Whether 8K is worth it from the viewer’s point of view depends a lot on the individual’s needs and the particular monitor. Acuity of vision, preferred viewing distance, overall monitor and screen size will all affect the viewing experience for the viewer. After we make these comparisons, 8K is the optimal resolution; of course 8K is certainly expensive, so you need to consider all of these factors to decide if 8K is worth getting.
