A:AnswerYes. You are able to mount this tv to a wall. It requires 4 bolts (M4), so make sure your mounting kit has those. I used an existing mount with vertical mounting brackets. They are real close to each other as the spacing between the holes is 100mm ( approximately 4 inches). I would recommend getting a VESA mount (100x100). The 100x100 refers to the spacing between the holes vertically and horizontally. That would be a perfect fit.
A:AnswerYes, I had it wall mounted by the geek squad. They did a fantastic job, and did not leave till I felt confident working the remotes. They also helped me get disney plus and HBO max.
A:AnswerIt's ver easy. You need only Netflix or Hulu account. But, if you have email account, you can use you tube.
But in general, the setup it's ver easy. Also, this tv is excellent; colors, image and others.
