What is 4K upscaling?
4K upscaling is the process by which a television or display device converts lower resolution content into a higher resolution, specifically 4K (3840 x 2160 pixels). This technology analyzes the original image and enhances it by adding extra pixels, leading to a sharper and more detailed visual experience. Upscaling is not limited to simply stretching the image but involves complex algorithms designed to improve the overall quality of the picture.
The goal of 4K upscaling is to make the content appear as if it was originally created in 4K resolution, even if it was produced in lower resolutions such as 1080p or 720p. With the rise of streaming services and older video formats, upscaling allows viewers to enjoy a more immersive experience on their 4K TVs without needing to replace all their existing content.
How does 4K upscaling work?
