A:AnswerI too went a little crazy trying to figure out how to mount it. I even called Sony and they told me the only Mount you could use was there mount. I knew this was incorrect. The directions literally such as far as putting on a mount for wall mounting. Then I realized in my Hardware it was a small package that is used for the lower attachment. Unfortunately I forgot exactly what it is but it looks like little cylinders period after you mount the TV with that it's good to go for any wall mount
