4K resolution is four times higher than Full HD and on the large 84 inch panel pictures should look stunning. The exact resolution is 3840x2160 pixels, which scales perfectly to Full HD (1920x1080) so your Full HD Blu-rays will play without scaling. To handle the massive picture information Sony has developed the 4K X-Reality PRO chip. The TV also supports passive 3D and utilizes the cheap polarized 3D glasses used in movie theatres. All 3D Blu-ray discs are automatically upscaled to the 4K panel.
The TV not only offers impressive picture quality but also a complete sound system. 10 speakers have been integrated and Sony promises and almost 3D-like experience with deep bass. A ClearPhase+ technology processes sound.
