A:AnswerIt shouldn’t matter so long as the position of the holes on your tv work in the vertical position. So 200x200 or 400x400 is easy as symmetrical. Then it’s about if the width of the wall mount is wider than the width of the tv when vertical so you might see it. But, bottom line, should be no issue mounting it. Another question is if the tv likes to be hung vertically!?
A:AnswerDepending on the tv weight and size. You can actually use just one stud. And toggle bolts on the side. Hit the stud as close to the middle as possible to top and bottom of the bracket. Then use toggle bolts on each of the 4 corner holes. You could also add extensions to the end.
A:AnswerThis mounting bracket comes with SO MANY screws that yes, it should work with your TV. Just be sure to try the shorter screws first because using longer screws may damage the TV. The mounting bracket comes with dozens of screws that are compatible with different TV manufacturers.
A:AnswerYou might be able to use the fasteners/mounting holes in the wall but use this appliance completely. Don’t find out the hard way that your assumption turned out poorly (mix and match option).
