I'm sure Jimsan will be able to give an authoritative answer on this one. Is Ambilight really nothing more than a worthless gimmick if you do not wall mount the Philips 9986? I know when I had one on test, as good as the picture was, I had the 9986 sat on a table stand, and I thought then that the Ambilight simply added nothing to the viewing experience. However, my neighbour has just purchased one after seeing it up and running, and on the wall in our local John Lewis outlet. The neighbour is now complaining to me that sitting on it's glass stand the Ambilight feature is virtually non existent. I did remark to the neighbour had he not noticed that the one he saw in store was wall mounted. I notice the current t.v. advertisement shows the 9986 on a wall as well.
