A:AnswerI can't comment on the Peerless SmartMount but can tell you that the Sanus VLF220 is compatible with your Samsung model and would be great option. The full-motion design allows you to extend your TV up to 20 inches and also offers tilting and swiveling options.
A:AnswerThe VLF220 is only rated to hold TVs up to 56'' so it is not recommended that you use it for your TV. The XF228 is rated to hold TVs up to 75'' and is compatible with your set.
A:AnswerThe VLF220 is designed for larger TVs so it is not compatible with your model. However, the Sanus MF110 another full-motion mount, is compatible with your TV set and available at Best Buy.
A:AnswerSimply push the release tab that clicks in from the TV's backet to the mount's arm. It is very easy and is how the TV mounts to the arm on this mount. It is all shown in the directions.
