A:Answer I bought the SANUS mount for mine...swings out about 2 feet from wall (or collapses/fold in straight against the wall if you want it safely stored while not watching. Also tilts and swivels any direction needed for viewing...very pleased with it. I installed this my self (super easy) two screws either drywall screws with sleeves (in my case) or two wood screws into a stud for the wall mount. Then screw adjustable frame onto back of TV using the extensive selection of TV mount bolts this SANUS package includes, make needed adjustments, attach TV to wall mount and screw secure screws into wall mount arm attachment so TV can't fall off and that's it.
If you don't want to install it, I can also tell you that we had Geek Squad install a 65" in our bedroom and I assure you that Geek Squad will do whatever they need (re: drywall question) to provide you a professional install.
