Disadvantages Of TV Wall Mounts. You can only mount your TV in certain places. Modern LCD and plasma TVs are still fairly heavy so you need to make sure the wall is strong enough to support your TV. Never fasten your mount to plasterboard because it is too weak and your TV will soon come crashing to the floor; instead you should only secure the mount to solid brickwork or wall studs.
Size is important too. It’s important for the bracket to properly support the shelf that it’s holding up. A common mistake is to buy brackets that are either to big or too small for the shelves. If they’re too big then they’ll stick out, and if they’re too small then the shelf could be unstable and dangerous. The projection of the bracket (the part that sticks out from the wall and holds the shelf) should extend to within an inch of the outer edge of the shelf.
