What’s the difference between 4K and 8K TVs?

Difference in resolution

4K and 8K all refer to the size of the resolution, which represents the number of pixel points that can be carried in the picture. The larger the resolution, the more pixel points there are, the more details of the object that can be expressed, and the more detailed and clear the picture becomes.

8K also achieves a greater level of advancement in terms of color depth and color gamut. 8K specifies a color depth of 12bit and is capable of displaying 68.48 billion colors, 64 times that of 4K. This enables 8K TV images to have increased resolution in a three-dimensional sense, with a smoother and more natural colour gradient.

HDR images

Not only that, but 8K TVs are also a great improvement over 4K TVs when it comes to HDR technology. HDR 4K TVs enable clear dark details and highlight details to be seen. In contrast, 8K TVs use Enhanced HDR, the second generation of High Dynamic Contrast Ratio technology, which greatly highlights the contrast between light and dark details and enhances the level of detail in the picture, so the picture of an 8K TV feels more deep and realistic.
