What is 4K Ultra HD TV?

The future of television has arrived. 4K Ultra HD TVs offer four times the picture resolution of 1080p HDTVs. Plus, all of the 4K TVs at Best Buy do a superb job of upscaling the movies and TV shows you currently watch to near-4K Ultra HD quality.

Beyond the technical details, this means the images you see will be incredibly realistic, with a level of detail you have to experience for yourself. Objects in the distance will appear with much greater clarity. Shadow and light will be more nuanced, black tones will be blacker, white tones will be whiter, and the entire picture will look sharper and have a greater sense of depth. 4K TVs with High Dynamic Range (HDR) will make your pixels look even better, with a dramatically wider range of colors and contrast.
