A:AnswerI'm not sure, I bought it for my 32 inch TV. It seems to be very sturdy, almost too big for my little 32 inch. The information included states it can support a 65 inch.
A:AnswerYes it swivels, the base is stationary. I needed a hacksaw to make all my ports available. Not sure if there is a way to check? I understand the TV manufactures have put the bolt patterns on the same place on the TV. You may be able template it out and see? I have a 65” LG on it. Even after modification its very secure and stable. It comes a big variety of bolts and adapters to get it to secure to your TV.
A:AnswerI have a 55 inch Vizio that was also mounted on the wall and used this stand and it works perfectly. It has many options for where the holes are on the back of the TV. It is very sturdy and we are happy with it. It does swivel nicely as well. It took about 45 minutes to assemble.
