A:AnswerI have mounted 5 different TV's on this from LCD to plasma, 32 - 60", including Samsung, LG, and Sony. Admittedly I never mounted a 70" or a Sharp, but with all the parts they include I cannot imagine a TV it wouldn't work for.
A:AnswerYou may need additional hardware for a Samsung - either the "holder rings" that come with the TV or purchasing different size screws than what come with the mount. Also, Sanus.com has a compatibility finder for their mounts.
A:AnswerI believe this is the same model that I have and it worked great. You should go in and talk to the sales people. They are great and can tell you what will work. The size specifications sound correct, but it depends on the place where you will be putting it up at. Talk to them before you buy one.
A:AnswerThe answerer who said towards the top of the mount behind the TV is probably the best answer. Presumably, since you are buying a tilt mount, you will be tilting it downward slightly. Installing the outlet toward the upper area of the mount gives more distance from the wall for your TV's wall plug when the TV is tilted down.
A:Answerwow only one stud. are you sure. but yes, as long you hit one stud you should be fine. just use mollys on the one that does not hit a stud. go to your local home improvement store and ask them where the wall mollys are located.
