Quick summary
A media wall looks clean because the messy decisions were handled early: mount height, power location, low‑voltage pathways, long‑run HDMI strategy, audio layout, and ventilation.
This guide walks through a practical planning sequence we use in Westchester homes so your wall stays tidy, gear stays cool, and the system is easy to control day‑to‑day.
Start with layout: viewing distance and height
Start by defining where you actually sit. If you plan your wall around aesthetics alone, comfort becomes an afterthought.
A simple baseline: center the screen close to seated eye height for your primary seats. If the TV must sit higher (fireplace layouts), verify comfort with a mock‑up and use a tilt mount to reduce neck strain and reflections.
If you’re still choosing a display, pick the right screen for the room and seating distance first, then design the wall around it.
Mount choice: tilt vs full‑motion
Most media walls work best with a quality tilt mount. Tilt helps with glare control and gives you flexibility when the TV is slightly higher than ideal. Full‑motion mounts are useful when seating is off‑axis or you need service access, but they require more wall reinforcement and careful cable slack planning.
- Tilt mount: clean look, reliable, great for glare control
- Full‑motion: helpful for corner seating and service access; needs more structure
- Always mount into structure (studs/masonry) and add blocking when needed
Power and low‑voltage routing (the clean‑wall core)
Power must be handled safely and legally. Don’t run extension cords in the wall. Use a listed in‑wall power solution or a licensed electrician to relocate an outlet where the TV and gear will live.
Keep low‑voltage (HDMI/Ethernet/speaker wire) on its own pathway and hardware. We typically place one low‑voltage bracket behind the TV and another behind the cabinet or media console so everything is hidden but still serviceable.
If you want real future‑proofing, add conduit between TV and cabinet so you can replace HDMI later without opening the wall.
- Separate power and low‑voltage pathways
- Use recessed boxes so plugs don’t push the TV off the wall
- Add conduit where upgrades are likely (TV ↔ cabinet)
- Label cables at both ends for future service
Cabling: HDMI, eARC, and when long runs need a plan
Short runs are simple: use a certified HDMI cable that supports modern features like 4K120, VRR, and eARC. Certified cables reduce the “mystery problems” that show up months later as dropouts or handshake failures.
Long runs are where planning matters. If your sources live far from the TV (closet rack, basement, long conduit), decide up front whether you’ll use fiber HDMI, active HDMI, or HDMI‑over‑Cat solutions. The right choice depends on distance, bandwidth, and serviceability.
We also recommend running Ethernet to the TV and cabinet. TVs, streamers, and smart‑home bridges behave more predictably when they’re wired.
- Use certified HDMI for 4K120 + eARC reliability
- Plan long runs (fiber HDMI vs HDMI‑over‑Cat) instead of guessing
- Pull Ethernet to TV and cabinet; reserve Wi‑Fi for mobility
Audio that fits the room (soundbar vs AVR)
The best media wall audio is the one your household will actually use. For many living rooms, a quality soundbar + sub is the sweet spot: clean look, great dialogue, and simple control through the TV remote.
If you want more headroom, wider coverage, or hidden speakers, an AVR or a streaming amplifier can drive in‑ceiling/in‑wall speakers and scale better in large spaces. The key is planning wiring and ventilation so it stays serviceable.
- Soundbar + sub: simplest path to strong dialogue and punch
- AVR + speakers: best for larger rooms and more immersive layouts
- Plan wiring now so upgrades don’t require wall surgery later
Ventilation, surge protection, and “quiet gear”
Media walls fail when gear cooks. Tight cabinets, stacked streamers, and receivers with no airflow lead to random glitches and premature failures.
Give equipment space to breathe, keep the cabinet organized, and add quiet ventilation if the enclosure is tight. Protect sensitive gear with surge suppression and consider a UPS for core components so short outages don’t scramble devices and settings.
- Leave airflow behind and above equipment; don’t pack tightly
- Use tidy power management and cable routing to prevent heat buildup
- Consider UPS protection for network gear and receivers in critical rooms
Control simplicity: keep it one‑button
A beautiful wall isn’t helpful if control is confusing. Aim for one daily remote and one obvious routine.
We typically enable eARC and basic CEC for simple volume control and power coordination. If CEC is unreliable in a specific stack, we step up to a dedicated universal remote or automation scene so the experience stays consistent.
- Enable eARC and confirm audio format support
- Use CEC for basic power/volume passthrough when it behaves
- If it’s flaky, use a dedicated control solution instead of living with frustration
Recommended gear
These items are practical building blocks for a tidy, serviceable media wall. Choose models that fit your wall structure and your room’s audio goals.
FAQs
Do I need conduit behind a TV?
You can build without it, but conduit is the cleanest future‑proofing move. It lets you replace HDMI later without opening the wall.
Should the TV be wired or Wi‑Fi?
If you can wire it, do. Wired connections reduce buffering and make control integrations more predictable. Keep Wi‑Fi for mobile devices.
Why does eARC sometimes act up?
Most eARC issues come from cable quality, device firmware mismatches, or CEC conflicts. Start with a certified HDMI cable and a simple signal path, then add devices one at a time.
Is a soundbar enough for a large room?
Sometimes. For very large or open rooms, an AVR or an amplifier driving architectural speakers usually provides better coverage and headroom. The best answer depends on layout and listening priorities.
Checklist
- Choose TV size and confirm mount height from your actual seating
- Plan power and low‑voltage locations before any holes are cut
- Add conduit between TV and cabinet where upgrades are likely
- Run certified HDMI and pull Ethernet to TV + cabinet
- Decide audio layout (soundbar vs AVR) and plan ventilation
- Make control simple (one daily remote, predictable scenes)
