We are hanging our 65inch TV using the bracket that came with the TV. The set came with 8 wall screws. We've located two studs, one in the left and one on the right. The stud on the left is rather wide and we've managed to get 4 (2 on top, 2 on bottom of bracket) screws solidly into the stud. The left side is a normal width so we can put 2 screws in. We were trying to put the remaining 2 in the plasterboard but has issues with the wall plugs grinding the plaster when the screw went in. We would love some tips to do this. We predrilled a smaller hole before putting in the wall plug and needed to hammer the last bit in.
The other question we have is would 6 screws be enough if they are all in the studs?
