How To Wall Mount a TV (Plasma, LED & LCD) – Abt Electronics, Shop TV Wall Mounts – http://www.abt.com/category/713/Flat-Screen-TV-Mounts.html

There are different types of wall mounts that offer varying motion options for your TV. Depending on the placement of the TV you may choose to have a flat mount a tilting mount or an articulation or cantilever mount. Each mount has specific benefits as listed below:
1. Flat/Fixed
This type of mount will keep the TV snug against the wall which allows for a clean look from the side of the TV. You will see no wires from the side view and the TV will remain in a fixed position as close to the wall as possible
2. Flat/Tilt
This type of mount will keep the TV close to the wall but allow for up to a 15 degree tilt. This is a great benefit when the TV is to be mounted higher on the wall such as in the case of mounting above a fireplace. The user can tilt the TV down in order to reduce glare or to make the TV easier to see from seating below.
3. Swing Arms
This type of mount will hold the TV off the wall in an increased distance from that of the flat or tilt mount. This mount will allow the user to swivel or pan the TV from side to side in order to increase the viewing angle of the TV. This is a beneficial option in a large room that has more than one group of seating that may be utilized in watching the TV
4. Articulating/Cantilever
Like the swing arm this type of mount will typically protrude a few inches off the wall. The ability to pull out and pan the TV up to 180 degrees allows the TV to be viewed from 2 different adjoining rooms. Another use for this type of arm would be when installing the TV in an armoire or entertainment cabinet the user could hide the TV inside when not in use and simply pull it out when its time to watch TV.,
