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.
A:AnswerThere are insructions and accessories in the stand’s box to adapt a curved TV to the stand, but since I didn’t need them for my 60” Samsung TV I cannot elaborate further.
A:AnswerI don’t work for Best Buy but from my experience with my own Ingsinia tv stand it is fairly easy to do yourself. All that is needed is a screwdriver. The instructions show 3 different tv “back” designs but it’s all the same. Build the base and screw the beams to the tv. I’m sure there is a YouTube video out there for step by step instructions for a visual learner.
