What is the difference between 8k and 4k (what is 8K8KUHD)

Video resolution and refresh rate are now higher, achieving 8K at 60Hz and 4K at 120Hz to meet the viewing experience and smooth picture details.

HDMI HD cable 2.1 appeared, its performance compared to other versions of a lot improved, 8K UHD with 7680×4320 resolution of ultra-fine pictures, for a variety of commercial, industrial and professional use. HDMI HD cable 2.1 dynamic HDR can ensure that every frame of the video, show the depth of field, detail, brightness, contrast of the color gamut, today we will take a look at what is 8K, 8K UHD, 8K resolution.

8K

8K refers to the horizontal resolution of 7680 pixels, and the resulting total image size is (7680*4320), also known as 4320p.

8K UHD, 8K resolution

8K resolution or 8K UHD is currently the highest Ultra High Definition Television (UHDTV) resolution in digital television and digital cinema technology.

The 8K resolution is 7680*4320 pixels, which is 16 times higher than the current mainstream HDTV and 4 times higher than 4K TV. If you watch Blu-ray movies on an 8K TV, the picture can only take up 1/16th of the screen.

High-resolution displays like 8K make it impossible for the human eye to distinguish every pixel when viewed at a normal distance from the screen.

8K resolution can also be used for video and movie editing by combining cropping techniques or techniques used in downsampling to create an enhanced, low-resolution video. Resolutions like 8K allow filmmakers to shoot wide shots and even greater distances with high resolution. Potentially dangerous subjects, such as wildlife documentaries, are digitally scaled and cropped in post-production. This technique involves cutting out part of the original 8K image and matching it to a smaller resolution, such as the current industry standard for HDTV (4K, 1080p and 720p).

8K TV display technology, 8K TV advantages

HDMI 2.0 or earlier HDMI 1.4 does not support very high resolutions, only 4K and below. The digital images we see are mainly full high-definition (2K) standards, with a resolution of 1920*1080, which is equivalent to about 2 million pixels. At present, the resolution of the new generation of 4K TVs that have attracted much attention is 3840*2160, about 8 million pixels, which is equivalent to 4 times that of full HD. Because the number of horizontal pixels is about 4000 pixels.

The pixel point of 8K products reaches 7680*4320, which is about 33 million, which is 16 times that of current full HD products. The sharpness of the displayed picture can be said to be extreme. When approaching Full HD products, the human eye can see pixels. However, no matter how close you get to an 8K product, you can barely see pixels. Vivid scenes reproduced in 8K clarity are almost impossible to distinguish between image and reality.
