It's quite simply the most immersive, highest-resolution TV experience possible. Sony's premium 4K Ultra HD TV boasts four times the clarity of HD1, more brilliant expanded color and up to two times the brightness range of standard LED HDTVs. Breathtaking detail is depicted with pinpoint accuracy for the most natural images. The TRILUMINOS display produces the widest color spectrum we've ever offered in a TV. Best of all, you'll enjoy Sony's exclusive X-tended Dynamic Range local dimming technology for up to 2x the brightness range with deeper blacks than before.
