The maximum resolution refers to the highest resolution the TV screen can display. This resolution is determined by the number of pixels the screen has and is generally expressed as width × height. Higher resolutions provide sharper images with more detail. Common resolutions include HD Ready (1280 × 720 pixels), Full HD (1920 × 1080 pixels), 4K Ultra HD (3840 × 2160 pixels) and 8K Ultra HD (7680 × 4320 pixels). Higher resolutions, such as 4K and 8K, are often useful for large screens or for high-resolution applications such as gaming or watching movies in ultra-high definition.
