I am finishing my basement and have metal studs on the perimeter (just in case of any moisture penetration. Planning on hanging an 85", 140 lb flat panel on the wall.
The drywall is not up yet, so I can do basically anything. Can anyone advise on the best thing to do? I have read a lot of differing opinions, like inserting 2x4s into the studs and screwing them together and then proceeding the same as with wood studs. Or else taking plywood and filling the spaces between the studs and then mounting with lag bolts into the plywood. Is there some overall best practice?
Let me add that it will be on a slim mount right up against the wall, not on an articulated arm or anything.
