What is 4k upscaling?

4K upscaling is a process that enhances the quality of lower resolution content, such as videos, images, or games, to make them appear closer to 4K resolution (3840 x 2160 pixels). This technology is commonly used in 4K Ultra HD TVs and monitors to improve the visual experience of watching high-definition or standard-definition content.

When a lower resolution video or image is upscaled to 4K, the algorithms used by the display device interpolate new pixels to fill in the gaps between the existing pixels. This helps to reduce the degradation in image quality that typically occurs when low resolution content is viewed on a high resolution screen.

However, it is important to note that upscaling cannot create true 4K resolution and may not always result in a significant improvement in image quality. The effectiveness of 4K upscaling depends on the quality of the upscaling algorithm used by the display device, as well as the source content being upscaled.

Overall, 4K upscaling is a useful technology for improving the visual appearance of lower resolution content on 4K displays, but it is not a substitute for true native 4K content.
