Newbie here. Would forum members be kind enough to provide guidance please?
I will be mounting a 46" LCD or plasma to a wall. Behind the drywall of this wall, where the TV/mount will be placed, there is plywood (instead of studs).
The mount comes with 2.5" screws, designed for mounting to wall studs. Should I use a different kind of screw, because of my plywood?
For example, my drywall plus the plywood will only be about 1.25" total. Would the 2.5" be inappropriate and somehow weakens the support?
