What's 8K (UHD)?
4 times sharper than 4K
The 8K resolution is 4 times sharper than 4K. This is because an 8K image consists of 7680x4320 pixels. In total, these are more than 33 million pixels, while the 4K resolution has 8 million. In practice, small details such as sand grains are more visible. Mind you, on screens up to 65 inches the difference in sharpness can hardly be seen with the naked eye. That is why 8K is especially added value when you buy a larger TV.
Little 8K footage
With only a few demo videos, no 8K footage is available yet. Although some films have already been shot in 8K, the current Blu-rays can not handle the large amount of data. For TV channels, a higher resolution costs extra bandwidth. For this reason, most programs are not even available in 4K. It seems logical that video services such as Netflix become the first providers of 8K images. When this happens, it is not yet known.
Sharper image thanks to 8K upscaling
The TV manufacturers are also aware of the limited 8K offer. That is why they develop advanced techniques that make images of a lower quality sharper. For example, the 8K TVs from Samsung with artificial intelligence add extra pixels to the image. As a result, your current film collection will be more detailed on a large screen.
