The most important thing to consider when looking for a wall mount for your TV is to choose one which suites your televisions specifications; this means you'll have to do a little homework. The most important specifications to know prior to buying a wall mount is your TVs:
Weight (without a stand)
Dimensions (width and height)
Bolt hole spacing for attaching a bracket (measured between the centres).
If you already have the TV you can take the measurements from the manual guide or measure it yourself. If you haven't yet purchased a TV you can either check these specifications from the retailer like Bing Lee, or look up the specifications from the manufacturers website. Choosing the correct TV wall mount for your television and wall that you mount it on is essential, and can easily turn into a hassle if you don't consider all the features.
Some Initial Quick Steps when buying a TV Wall Mount include:
Check that the weight of your TV does not exceed that which the bracket is capable of holding.
Make sure that your TV's width and height are larger than the bracket, this will ensure that the installation is tidy. A bracket that is too large can look untidy as well as be unsafe, and one that is too small may not be sufficient in carrying your TV.
The space between the brackets must be bigger than that of the bolt hole spacing of your TV if you're buying a universal TV wall mount. If you're buying VESA brackets, there must be a match with your TV's bolt hole spacing.
The rear clearance, measured by the depth of the bracket or the space between the wall and the TV, must be large enough for the cabling, power points and any wall plates.
CHOOSING A WALL MOUNT THAT SUITES YOUR WALL
Most of the time any TV wall mount will fit on your wall, however large TVs require large brackets, and this in turn means that your wall will need good load-bearing structural support. Also, for timber frame homes the TV wall mount must be placed on a spot on the wall where there are two available studs and also where there is no electrical wiring in the way. So, make sure that your intended wall has good enough support for your TV size and the width of the bracket. There are some ways to get around this problem if your studs are not compatible with your bracket width and the wall support isn't sufficient. Firstly, you can choose a different TV wall mount that fits with the width of your walls' stud(s). Another solution is to install a load-bearing false wall or panel between the available studs that can provide a secure anchor point at the correct place.
However, if your walls are solid timber, concrete or masonry these placement and support problems don't apply and most TV wall mounts will be compatible.
TYPE OF FLAT SCREEN TV MOUNTS
There are three main styles of wall bracket types, and they have some distinguishing features. Each design of wall mount has it's own strengths and weaknesses, and this buying guide aims to make these clear to you so that you can choose the most appropriate style.
Flush and Low Profile TV Wall Mounts
These slim brackets mean that your television will be very close to the wall, giving a picture frame like effect. This type of TV wall mount is a fixed motion mount, which means that the television will not move once the wall mount has been installed to the wall. An advantage of this style of TV wall mount is that there is nearly no space between your TV and the wall and it attaches nearly flush to the wall. A Low Profile TV Mount is recommended to you if you don't need to adjust your TV and it's at an optimal position for viewing. A downfall of this style of mount is it has limited cabling access; so ensure that your TV has side-ways or downwards facing power and AV sockets so that they won't be poking into the wall. You may also need to consider investing in cable management components like right-angle HDMI adaptors and wall plates to make sure everything looks organised.
Tilting TV Wall Mounts
These are similar to Flush/Low Profile TV Wall Mounts because they sit very close to the wall (generally around 1 to 2 inches from the wall), however what distinguishes them from the others is that the brackets are able to tilt the TV up and down for improved viewing angles. Tilting TV Wall Mounts offer a flexible compromise between low profile and extending wall mounts. This style of TV Wall Mount is particularly helpful for adjusting your TV for a better viewing angle, when there is sunlight glare, also for mounting your elevated TV higher up the wall if you want to avoid having it close to children or pets.
You must consider that Tilting Brackets need more rear clearance to account for giving the movable arms space and avoid damaging your wall, so it's not ideal if you have a small space. The amount of tilting angle varies depending on the TV wall mount, but it usually runs between 5 to 15 degrees. The TV is kept in place by a locking mechanism, and so are generally very safe.
Extending or Dual Pivot TV Wall Mounts
This style of TV Mount offers total flexibility and versatility, and so is perfect for recesses, corners and exact placement flexibility. An Extending TV Wall Mount allows you to pull the TV out of the wall, swivel it both left and right and tilt it up as well as down. Before buying an Extending or Dual Pivot style mount, it is important that you make sure that the wall and mounting point you intend to place it is very secure and stable.
Extending/Dual Pivot brackets require sufficient cable slack and management to make sure that all AV and power connections will not unplug when they are at full stretch as the TV is moved around. DIY jobs are not recommended for inexperienced installers, as more factors must be considered to ensure safety and stability.
