A:AnswerI imagine it does. It has many mounting options for both flat and curved backed televisions. The arm moves in many directions and without a tv mounted to it, the mount does go a full 180 degrees. With a tv mounted it only goes as far as the edge of your tv will allow it to. Your tv will have greater range of motion than a larger tv. And your tv will have less range than a smaller tv. The mount hugs the wall pretty well. You can mount it high and have the screen point downward. The arm has a tons of positions you can take advantage of.
