Will movies and shows from regular home cable and entertainment systems appear different on a 4K TV?

High Definition (HD) and standard definition (SD) content such as TV shows, DVDs, Blu-ray Disc® (BD) movies, and Internet streamed movies or videos will appear better when viewed with a Sony® 4K TV. This is due to the 4K X-Reality™ PRO Picture engine, an exclusive up scaling technology of Sony TVs, that enhances and refines picture quality from all sources.
