A:AnswerNot sure about your TV, but this mount is very sturdy. As long as you mount to studs as recommended it’ll hold a ton of weight. I would suggest not to exceed the manf. Specs.
A:AnswerI don't see any reason why it wouldn't work. As long as the Vizio weighs less than the recommended max weight you should be fine. Hole patterns on the back of the TV should be fine. I'm using this mount with a 55" Hisense TV with no issues.
A:AnswerYes this Can mount a TV to that specification as long as the very detailed Instructions are followed.
It also includes several different size mounting screws and spacers to mount flat backside or curved backside TV and gives excellent instructions for mounting it properly with studs.
