I've seen this question asked before, but didn't see what hardware to use in putting up the plywood.
I'm looking to mount my 65" TV above the fireplace using an articulating mount that mounts across 2 studs 16" apart. The problem: there is a stud in the center of the fireplace, leaving my TV off center when mounting.
Mount + TV weight: 74 lbs.
I've read you should use 3/4" plywood between 3 studs (16" apart) that is 3" more than the height of the mount and then put up the mount anywhere along the plywood. PLEASE CORRECT ME IF I'M WRONG.
If that mounting method is viable, what type of lag bolts do I use to mount up the plywood? I see so many different sizes that are available.
Also, once the plywood is up, do I use the lag bolts provided by the TV mount to mount the mount to the plywood? (that sounds weird lol) Lag bolts provided with the mount are listed as M8x55 Lag Bolts.
