A:AnswerI read your question and thought i would check and see if i could.I have the same tv. I went into the menus and tried to no such luck.I think it depends on how the movie was made cus i have 3d movies some have bars and other ones are full screen.Either way i enjoy the 3d movies.You could try for yourself by going into the picture options scroll down till you get to picture size select that and it will give you three options to adjust picture size. Some movies it will allow you too get rid of the black bars and other movies not.
