8K (UHD) Explained

What is 8K (UHD)?

The 8K resolution is 4 times sharper than 4K. The arrival of 8K TVs seems very early, as there are no 8K images available yet. Nevertheless, an 8K TV is worth considering thanks to smart upscaling techniques. In this article, I will tell you all about it.

4 times sharper than 4K

The 8K resolution is 4 times sharper than 4K. This is because an 8K image consists of 7,680 x 4,320 pixels. In total, these are more than 33 million pixels, while the 4K resolution has 8 million. In practice, small details such as grains of sand are more visible. Note that on screens up to 65 inches, the difference in sharpness is barely visible to the naked eye. That is why 8K is especially an added value when you buy a larger TV.

With the exception of a few demo videos, no 8K footage is available yet. Although some movies have already been shot in 8K, today’s Blu-rays can’t handle a 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 most logical that video services such as Netflix will become the first providers of 8K images. When this will happen is not yet known.

The TV manufacturers are also aware of the limited 8K offer. That is why they develop advanced techniques that sharpen lower-quality images. For example, Samsung’s 8K TVs with artificial intelligence add extra pixels to the image. This makes your current film collection more detailed, especially on a large screen.
