The term 4K for TVs refers to a display resolution that is four times the pixel count of a standard 1080p high-definition television. Specifically, 4K resolution has a resolution of 3840 x 2160 pixels, which equates to approximately 8.3 million total pixels. This is significantly higher than the 2 million pixels found in a 1080p display, resulting in a much sharper, more detailed image with greater clarity and vibrancy. The increased pixel density of 4K allows for larger screen sizes without sacrificing image quality, and also enables better upscaling of lower-resolution content. As a result, 4K TVs are able to deliver a more immersive and visually stunning viewing experience compared to their 1080p counterparts, making them the current standard for high-end televisions.
