HD tailors the concept wherein you may feel for that point of moment when the footballer is about to score or when you watch something scary that you are in that situation but what is shown is something that comes out of the screen which would be the case of a 3D concept. This must be brought out correctly in advertisements some website also show 3D representation of images (coming out of the screen) this may be wrong because if 3D had to be launched they would be contradicting their very own line of HD.
