A:Answer Yes.
I attached my 58" Samsung to a vaulted ceiling (the TV is at a 45-degree angle {top angled back}) using this mount - works great and was easy to install.
Since my situation was a bit extreme - in a flat against the wall configuration, using this mount for your TV, should do just fine for you too. NOTE: you will need a long Phillips screwdriver to tighten down the TV brackets to the mount. I bought a 10" extension for my screwdriver at ACE hardware for about $8.
