A:AnswerHi robbie - The type of wall mount you choose depends on your setup style. For a clean, flush look, consider a fixed mount or our Slim Fit Wall Mount. If you’d like the flexibility to adjust the angle or position of the screen, a tilting or full motion mount is recommended. The 55" Q7F TV supports any universal wall mount that matches its VESA pattern of 200mm x 200mm.
