8K UHD TV refers to a television display with a resolution of 7680 x 4320 pixels, which is four times the resolution of 4K UHD TV and sixteen times that of Full HD TV. This high pixel density allows for incredibly detailed images, making it ideal for large screens where viewers can sit closer without noticing pixelation. In addition to resolution, 8K UHD TVs often support advanced technologies like HDR (High Dynamic Range) for improved color and contrast. They also typically include smart features, allowing users to access streaming services and apps directly from the TV, enhancing the overall viewing experience.
