<br>Neither Samsung A950 nor Sony XBR8 series do include a <b>3-D HD content support</b>. In other words, one cannot use these LED LCD TVs to display 3-D games, movies, and other 3-D HD programming - which in addition to a suitable HDTV, requires also the use of a 3-D compatible LCD shutter glasses and relevant hardware. The so-called '3D' features found on the Sony refers to [1] <b>3D-Comb filtering</b>, and [2] the <b>3D graphics style menu</b> used when setting up your Favorites and Photo-Slides show functions. These are not 3-D HD content features as the sales-rep might have implied. Note that <b>3D comb filtering</b> or 3D Y/C - is used on many premium class HDTVs. This is the best type of comb filter available today and is used to separate the Y (luminance, or black and white levels) and C (chrominance, or color) elements in a composite video signal. It is called 3D because of the way it analyze the incoming signal in the separation of the Y and C components - namely apart from separating these signals, is also compares three consecutive horizontal scan lines within a single video frame, as well as analyzes each frame in advance, thus ensuring the best possible picture. <br><br>
