8K vs 4K Resolution

News / 29.07.24

From HD to Full HD, then to 4K, and now to 8K resolution, each leap brings with it a new level of clarity and detail. As technology rapidly advances, the pursuit of higher resolution and more immersive visual experiences continue to push boundaries.


Understanding 4K and 8K Resolutions


4K Resolution

4K, also known as Ultra HD, boasts a resolution of 2840 x 2160 pixels, which is four times the number of pixels found in Full HD (1080p). The higher pixel count results in sharper images, more detail and a better overall viewing experience, especially on larger screens.


8K Resolution

8K takes visual fidelity to an even higher level with a resolution of 7680 x 4320 pixels, offering four times the pixel count of 4K. This means an incredibly detailed and lifelike image that remains crisp even on very large displays. The improvement is especially noticeable in terms of depth, texture and realism, making it ideal for professional applications, gaming and future-proofing home entertainment systems.


Key Differences Between 4K and 8K

  • Pixel Density: The most significant difference is the pixel density. 8K offers 33.2 million pixels compared to 8.3 million in 4K, resulting in finer details and more immersive visuals.
  • Viewing Distance: 8K’s higher resolution allows for closer viewing without loss of image quality, making it perfect for large screens and professional displays.
  • Content Availability: Currently, 4K content is more widely available compared to 8K. However, as 8K technology becomes more mainstream, more content will be produced to meet demand.
