I'm finding a lot of conflicting info on this.
I have a 53.1 lbs TV (65") that I want to mount using a flush mount (5.9lbs) to my wall. However the studs (24" apart) are off center so I would be looking to mount it on the center stud.
I live in a building that's about 12 years old, so modern construction. I've seen advice from "yes, snap toggles on the stud and anchors on drywall will do" to "you need a piece of plywood across 3 studs and then you can center your mount"... (as for that last one, the rightmost stud has electrical running through it so it complicates things even more!)
