A:AnswerThere are a total of 4 mounting holes. 2 of them have screws in them, and should be removed. We recommend using the appropriate M6 screws that come in the mounting bracket screw kit. This TCL Roku TV uses a 100mm x 100mm VESA mounting pattern. You can also visit https://support.tclusa.com/283050-how-to-choose-the-correct-wall-mount for more information about mounting.
