The 8K (UHD-2) resolution
A short while ago, 4K (UHD = Ultra High Definition) resolution was regarded as the norm. Additionally, while 4K technology and content haven't truly reached "the public" yet, the successor 8K has already started to take shape. The following information about the 8K resolution is fascinating:
What exactly is 8K?
The successor to 4K (UHD) is 8K, which is described as UHD-2. There are roughly 8,000 horizontal columns in the 8K resolution. Or 7,680 x 4,320 pixels, which is four times as many pixels as 4K and sixteen times as many pixels as Full HD, dispersed over the corresponding display size in the traditional 16:9 format.
This indicates that the display has 33.2 megapixels, or about 33.2 million pixels. Additionally, 8,192 by 4,320 pixels at a ratio of roughly 17:9 are referred as as 8K. However, this resolution barely applies to consumer electronics due to the somewhat peculiar page format.
Where does 8K make sense today?
Not just for early adopters in technology, new 8K cables and adapters are already a smart idea. Since 8K items are backwards compatible, the price difference from 4K products is not very big. Gaming and home cinema fans who use large screens may already take use of 8K. Another intriguing development for gamers is the 2020 release of the new Xbox and Playstation, which both allow 8K streaming and are 8K compatible.
There are other application areas besides the private sector. In addition to museums, art, and culture, we would want to mention science, research, and design. 8K is beneficial for large-scale presentations using projectors or LED walls, such as those used to display models, simulations, or even creative animations or installations. The increased level of specificity and the increased colour brilliance are a clear advantage for the viewer.
Can you see a difference between 4K and 8K?
In general, this question cannot (yet) be addressed. The degree of distinction relies on a number of factors, including the hardware and individual eyesight, in addition to the viewing distance and 8K screen size.
To put it simply and generally, less pixels per inch are needed to prevent "pixelation" the farther away the viewer is from the screen. For instance, a smartphone, which is frequently held nearer to the eye, needs a higher pixel density than a conventional television.
At 8K, the pixels are smaller and closer together, which can be seen as an improvement in the level of detail and depth in the images. The 12 bit color depth also makes colors appear more vivid. Each observer will experience higher detail and more vibrant colors differently.
In the schematic picture above, the enhanced precision from Full HD to 8K is demonstrated. It displays the corresponding subpixel structure for each resolution using the same section in every instance. A subpixel in Full HD is quite big; you see 4 × 4 = 16 pixels. 8 x 8 = 64 pixels is the quadruple number of pixels provided by 4K. With 8K, the pixel count is once more quadrupled (16 x 16 = 256 pixels).
How can 8K content be transferred?
It takes work to transfer the 8K data, which is difficult in terms of volume. Only HDMI versions 2.1 and later provide enough capacity to transport 8K content at a 60Hz frame rate.
Additionally, only this version enables 4K 3D 50/60p and 14 and 16 bit color depth, which HDMI 2.0's predecessor was unable to do. HDMI 2.0 often "only" supports 4K. DisplayPort version 1.3 adds 8K capabilities.
