In order to determine what TV is compatible with your Rocketfish wall mount you will need to verify three things: first, that the size of the TV is within the listed ranges, second, that the weight is within the listed ranges, and finally, that the mounting pattern is the same.
All of this information can be found in the owners manual for your product. A copy of the manual is located on the Support and Downloads tab of your products page which can be found by searching for your model number in the upper right hand corner of this page.
