Sony recently launched its BRAVIA 84-inch 4KTV. An example of design, engineering and consumer electronics wizardry, the XBR-84X900 4K (3840 x 2160) LCD panel that delivers four times the resolution of Full HD. Outfitted with all the latest technology available to Sony 3D-enabled HDTVs, the gargantuan BRAVIA makes its debut this November for $25,000. 4K content is still sparse as this is cutting edge technology.
