Sony was also the first TV maker to achieve a significantly wider color range in their 4K TVs by enhancing the LED backlight. Originally, Sony used nanocrystals to produce purer blue, green, and red light, from which the TV's entire colour palette is created. Their latest TRILUMINOS™ Display system produces the deep, true colors of nanocrystals, using technology that better complements Sony's new X1 video processing engine, and also allows a much thinner LCD panel. Right now, the way to see the best possible 4K picture from the XBR-65X900C is to connect it to Sony's FMPX10 4K Ultra HD media player, which lets you access a library of full-length 4K Ultra HD feature films and TV shows from your living room. You can download titles from Sony's Video Unlimited 4K Store and load them on the FMPX10's built-in hard drive.
