I looked at the list of "Accessories" for the mount on the main Sony website and it didn't list your model. The closest was XBR-55X950H. They aren't very specific which is weird. I did a Google search to answer your request for compatible mounts resulting in this answer. "To find TV mounts with the same VESA pattern, you can measure the distance between the mounting holes on the back of your TV. The SANUS MountFinder tool can be used to determine what TV wall mounts will fit a TV". https://www.sanus.com/en_US/mountfinder/#!step1 Try this webpage to find a compatible mount.
Also, just so you know. This mount only allows side to side movement. No tilting. It is extremely strong which I like but tilting would have been nice as our ceiling light reflects on the TV screen and there is no way to move our TV to lose the reflection. Sony screens have a rainbow refraction of light that we didn't have on our previous Samsung curved screen. We really liked the curved screen for our application. Alas it didn't catch on.
I hope this helps you find a compatible mount.
A:AnswerJohn,
I'm afraid I can be of no help as the Geek Squad installers told me my current wall mount would not have to be replaced by the SONY mount. Thus, it was returned for credit.
