When your LCD TV is heavy then you need a wall mount which is equally strong and sturdy. To have the sturdy flat panel TV mount you will need to buy a TV mount which has not much features but is built to withstand huge extreme weights.
There are very few manufactures who build the TV mounts that can be easily used for the extra large and extra wide LCD TV or the plasma TV's. That is why if you are buying a TV 40 inches of above make sure that you buy the heavy duty tilting flat panel TV mount from the same shop itself.
Most of the heavy duty mounts do not have the articulating arm as they just cannot support the weight. These are normally fixed and are used mostly by the large retail shops to display the TV's in their showrooms. Most of these are custom made so that they do not have to rely on the sub standard mounts.
The tilting functionality is a must as without that the viewing experience will not be there. However these stand do not have the swivel experience and the maximum tilt that these can have is only about 15 degrees.
Before buying make sure that the manufacturer is following the VESA standards and also check at the back of the TV television for any extra specification that have been given for the TV mounts. Always check the warranty period for the mount and also have the service engineers come to your home and fix the it as these are heavy and you for sure cannot do it all by yourself.
