So I'm attempting to mount my 55" Samsung LED between 2 windows, but really only have 1 stud to center it perfectly in the middle. The workaround I've heard is to put a plank across the 3 studs, paint it the same color as the wall, and hang your mount from that. That is what I'm going to attempt to do, but I wanted to get approval from you pros first. I'm honestly not terribly handy so opening the wall to install braces and such isn't an option.
Some things to note:
A. It's an articulating wall mount
B. TV and mount together weigh 70lbs.
My questions are:
1. Is a 3/4" thick, 36" x 14" plank (plywood?) ok? Overkill?
2. I'm assuming I put long lag bolts through the top and bottom of the mount, plank and center stud.
3. Should I toggle bolt through the mount, plank and drywall everywhere else (maybe 6-8 of them)?
4. Any problems I might have trying to run cables behind the wall since I now will have to cut a hole in the plank AND drywall?
Any insight on this is greatly appreciated.
