A mounting that enables the attachment of a flat-screen TV, such as an LCD or Plasma, to a wall is called a TV bracket. It not only saves a lot of floor space but also allows you to place TV screen at a height most suitable for viewing.
TV brackets come in different designs and styles, and most have features like tilting screen up and down and/or swivelling to all sides. By tilting the screen up or down you can view the TV more comfortably, while swivelling enables you to view the screen even from an adjoining room.
If you want the screen to remain in a fixed position, you can make use of TV brackets which hold the TV in one position and do not permit alteration. Although cheaper, these fixed TV brackets make it a bit more difficult to get behind the screen to swap cables.
To ensure that a bracket is suitable for the type of your TV, you should either buy one recommended by the manufacturer of the TV itself, or select a universal one that is listed for your TV model number. Most TV brackets are assigned FDMI rating which guarantees standard size and shape of bracket, produced as per the VESA (Video Electronics Standards Association) guidelines. However, most brackets without an FDMI rating can also be equally good in quality.
While selecting TV brackets you must also check for a load-bearing capacity figure, which indicates maximum weight of screen that the bracket can take for holding the TV securely. Sometimes brackets will list screen sizes which they are capable of handling.
