The only reason I ask this is I am in the market for a new set, possibly 60 inches, most likely 65 but I sit a little less the 11.5 ft away currently from a 60 inch which is fine. I read on another forum that someone had a 60inch Panasonic Plasma and the maximum distance for the glasses were 10.5ft as stated in the Panasonic's instruction manual. Suffice to say he did not see 3D from his seat distance which was at about 11ft, until he moved up. Does this also apply to the other brands because if that is the case then I can't buy a 3D set at this time, being that my furniture is actually non adjustable at this point.
