Outdoor TV mounting in Hobart
Mainland guides on outdoor televisions worry about heat and UV. In Hobart the problems are cold, damp and wind, which fail a screen differently and more quietly.
- Penetrations sealed properly
- Fixed into framing, not cladding
- Honest about what will not last
A standard television in a Hobart alfresco area will usually work and will usually not last. The killers here are condensation from cold-to-warm cycling, damp, and wind load on exposed elevations, not the heat and UV that mainland advice is written around.
Why Hobart is a different problem
Outdoor television advice written for Queensland is about heat, glare and UV degrading plastics. Those matter less here. What matters is that a chassis which is warm while running and cold overnight will pull moist air through itself as it cools, and that moisture condenses on cold electronics.
Most consumer sets specify a minimum operating temperature somewhere around 0 to 5 degrees. A screen in an unheated Hobart alfresco spends a good part of winter below that. It rarely fails dramatically; it corrodes, develops intermittent faults, and dies a year or two early.
Three levels of doing this
1. A standard TV in a genuinely sheltered spot
Fully undercover, walls on two or three sides, out of driving rain and not in the wind. This works acceptably for a set you are not precious about. Expect a shorter life and accept that heat damage and moisture damage are generally warranty exclusions.
2. A standard TV in an enclosure
A weatherproof housing around a normal screen. Considerably cheaper than an outdoor television and effective in a sheltered position. Two caveats: enclosures are bulky, and they need ventilation designed in or you trade a damp problem for a heat one.
3. A purpose-built outdoor television
Sealed against moisture and insects, rated for a wider temperature range, and much brighter so it is watchable in daylight. It costs several times a comparable indoor set. For a covered deck you actually use through the year, it is the option that stops being a false economy.
Mounting on an exterior wall
The fixing matters more outside than inside, because a mistake lets water into the wall rather than just loosening a bracket.
- Weatherboard. Fix through to the framing behind the cladding, never to the boards alone, and seal every penetration.
- Brick and masonry. Straightforward with the correct anchors. Fix into the brick face rather than the mortar joint on exposed elevations.
- Fibre cement sheet. Locate the framing; the sheet carries very little on its own.
- Stainless fixings. Worth it near the Derwent and anywhere with salt air. Standard fixings weep rust down a wall within a season.
Wind, and why full-motion is the wrong choice outside
A 65-inch screen is a sail. On an exposed western or southern aspect, a full-motion arm holding it away from the wall multiplies the load and puts it somewhere the bracket was not designed to take. A fixed mount tight to the wall is both safer and steadier.
Power and cabling outside
Any outdoor power outlet is licensed electrical work, and outdoor installations have their own requirements under the wiring rules including weatherproofing and RCD protection. That is an electrician’s job, and worth planning before the screen goes up rather than after. Cable and outlet options.
When we will tell you not to
An uncovered deck. A position that catches driving rain from the west. A screen you care about, in an unheated space, over a Hobart winter. In those cases we will say so, and suggest a portable option or a different wall instead.

Useful answers before the appointment.
Outdoor television questions answered for a cold, damp, windy climate rather than a hot one.
People do, and it usually works for a while. The failure modes are condensation inside the panel, corrosion on the board and insects getting into the chassis. An undercover position reduces rain exposure but does nothing about humidity or cold.
Different rather than harder. The mainland problem is heat and UV; Hobart is cold, damp and windy. Repeated cold-to-warm cycling drives condensation inside a chassis that was never sealed for it, which is the quiet killer.
Most consumer televisions specify a minimum around 0 to 5 degrees. Hobart overnight temperatures drop below that regularly in winter, so a screen left in an unheated alfresco area can spend months outside its rated range.
A purpose-built outdoor television is sealed, brighter and rated for the temperature range, and costs considerably more. An enclosure around a standard set is cheaper and works well in a genuinely sheltered spot, but adds bulk and needs airflow.
Yes, into the framing behind the cladding, with the penetrations properly sealed. Fixing into weatherboard alone is not adequate, and unsealed fixings in an exterior wall let water into the wall cavity, which is a bigger problem than a loose TV.
Worth taking seriously. A large screen is effectively a sail, and full-motion arms are the wrong choice on an exposed elevation. A fixed mount close to the wall is far better on the western and southern aspects that catch weather here.
