3D & HD Output

The difference is full HD and 3D

          Now you can wirelessly stream content with spectacular clarity up to Full HD 1080p5, plus stream 3D video sources that let you take advantage of everything your 3D HDTV has to offer. While some manufacturers wirelessly stream content at a lower-quality resolution, Sony devices like the Streaming Player with Wi-Fi deliver the Full HD experience—and the results are staggering. Once you see the difference, you won't want to settle for less.
