Tech Talk – Flat screen TV on your wall

Author: Peter Dobson


Having a flat screen wall mounted at your place can be quite an attractive proposition, both in terms of aesthetics, and safety. So not only can it look great, it keeps the television away from curious pets, or inquisitive children.

We offer this service as part of our business and have installed many over the years. We also have mounts available for anyone who may like to try it themselves.

Although there are some basic principles involved with installing a flat screen on the wall, there are many variances from place to place based on things like: Size and weight of television, area you want to mount it, whether your component switching is done on a separate unit, wood or steel (or none) studs, proximaty of power to the area you wish to mount, the variances go on..

Previous customers have stated to us everything from, “please don’t cut holes in our wall” –  through to “I want the best options available so rip my walls to pieces and we will get it re-jibbed!”

What ever your preference, it’s sometimes unavoidable to cut holes into jib to run cables, be it mains cables to power your television, or AV cables.

Hiding cables in an already jibbed wall can be challenging

Prior to cutting jib it is imperative you have a better than general idea as to where the studs run in your wall, also beneficial to know is whether your studs are metal or wood.  There are a few tried and tested methods for finding studs in the wall. Firstly you have the tap method,(differing sounds as you tap) which can give you a general idea as to where studs are, but often not a definitive idea of the width or even which direction they run in.  Stud finders are another option, however in our experience, even the more expensive units are by no means 100% accurate.

Metal studs can be detected with a strong magnet, but again definitive locations aren’t always guaranteed.

Once you have an idea of the  general area that you want your TV to hang, workout the height above the ground etc, make some general calculations as to where the mount will be. Draw a pencil line of the outline of the mount. Now you can start getting serious about finding studs to fix to. It’s also  time to think about your power source for the TV, and be conscious of potential existing power cabling in the wall.


Have a plan as to how you will run cable from your existing components (Blu ray, Satellite receiver etc) to your wall hanging TV. Alot of modern TV’s now have a single (own brand) lead to an HDMI input box, allowing you easy access to HDMI ports whilst having a single (own brand) lead fixed inside the wall.

Finding Studs

So now you know generally where the mount will be fixed, you have done the tap test to get some ideas of stud locations. It’s now time to get some exact locations and widths of studs, to ensure your mount is well anchored to the wall. The method we find the quickest and most accurate is to take a small nail, and a pair of pliers. Push the nail into the wall. If the nail goes all the way in – NO STUD. If the the nail goes half way in, STUD. From there it’s a matter of prodding to find the direction, width of the stud.

These tiny pinholes will be hidden by the TV once mounted, so no issue there.

From there you need power and AV Cables run. You may like to get us in to finish the job from there. As it is not recommended you install 240 volt power sockets unless you are a qualified electrician.
