Sony’s Reference Standard for UHDTV
The X900B Series, meanwhile, also uses X-tended Dynamic Range Pro processing, but has an edge-lit LED backlight. It also has a new Wedge design with built-in front-facing Magnetic Fluid speakers—a feature that X950B Series sets omit.
The X950B Series will be available in 65- and 85-inch screen sizes and the X900B Series in 55-, 65-, and 79-inch screen sizes. A third UHDTV line, the X850 Series, consists of four models ranging from 49 to 70 inches. Sony says that all of its UHDTVs will ship in spring.
