Good TV cable management starts before the television goes on the wall. Planning where power, HDMI, aerial and network connections will run can prevent visible cable loops, strained sockets and awkward equipment placement later.
Plan the cable route before drilling
Start by listing everything that needs to connect to the television: power, HDMI devices, aerial or satellite feed, network cable and soundbar. Decide where consoles, set-top boxes and streaming devices will live. A tidy result depends on where cables begin and end, not just on hiding the short section behind the screen.
Keep mains electricity and signal cables in mind
A mains power lead should not be improvised inside a wall or trapped behind a bracket. Any new socket, concealed mains wiring or alteration to a fixed electrical installation needs an appropriate qualified electrician. Signal cables can sometimes be routed through suitable surface trunking or planned wall pathways, but the correct approach depends on the wall construction and relevant electrical safety requirements.
Measure with the bracket extended
A fixed wall bracket needs less movement than a full-motion arm. If the TV tilts, swivels or pulls forward, leave enough slack for the complete range of movement without stretching connectors or creating tight bends. Check the position of the ports: some face downwards, while others face sideways or towards the wall.
Choose the right cable lengths
Measure the route rather than the straight-line distance. Allow for bends, the bracket’s movement and a little service slack, while avoiding large coils behind the screen. Very long HDMI runs can introduce reliability problems, particularly with demanding 4K high-refresh-rate signals. Check cable specifications and test the full source-to-screen connection before concealing anything.
Decide between trunking and concealed routes
Paintable surface trunking is often practical in finished rooms because it is accessible for future changes. Concealed signal cable routes can look neater but may require additional work and depend on whether the wall is masonry, plasterboard or a stud partition. Avoid cutting structural elements or drilling without checking for existing pipes and cables. Our wall mounting and hidden cables guide explains the wider planning considerations.
Keep equipment ventilated and reachable
Games consoles, amplifiers and television boxes need ventilation. Hiding them in a tightly closed cupboard can cause heat build-up and make troubleshooting awkward. Consider whether remote controls need line of sight and whether you can reach power switches and ports. Leave room to replace a cable without removing the entire installation.
Test the whole setup before finishing
Connect each source and check picture, sound, remote control operation and network performance. If you use a soundbar, confirm the correct HDMI ARC or eARC connection and settings. Our TV HDMI planning article can help you identify what needs connecting before installation day.
When to ask for installation help
A professional assessment is useful when a wall type is uncertain, a large screen needs secure support or several cables must follow an awkward route.
