Your TV has four VESA mounting holes on the back. If you attach a
wall-mount bracket to the back of your TV, the bracket must
be securely attached, using all four holes. If you do not use
all four mounting holes, your TV may fall and cause property
damage or personal injury. See the documentation that
came with your wall-mount for complete mounting
instructions.
