Yes, you can use this wall mount for your Samsung 55 inch TV as long as the VESA dimensions of your model are 100 x 100 mm to 600 x 400 mm and the weight is less than 60 kg. The mount is designed for screen sizes up to 84 inches, and many Samsung 55-inch models such as the QE55Q60D have VESA 200 x 200 mm, which is compatible.
