Choosing the right mount is not difficult, but it does require that you consider how and where your flat panel will be used. In general, there are 4 criteria for you to consider: Viewing Area, Viewing Height, Viewing Flexibility/Convenience and Room Lighting. For instance, if you will be placing your flat panel up high over a fireplace, a fixed mount can’t give you a good viewing angle. If you have a window behind your sofa, you should consider a tilt mount. Or, if you have a great room or game room with a wide viewing area, you're probably going to want a cantilever mount - either manual or motorized. In an effort to guide you through the selection process, here are some helpful hints for determining which type of mount you should choose.
