You’ve got two solid paths, depending on your setup and comfort level:

• In-wall cable management kits: These route low-voltage cables (like HDMI or Ethernet) behind the drywall and typically include recessed plates for a wall mounted TV. Many kits also provide a way to add recessed power near the TV, which can help meet common code considerations. This delivers a very clean, built-in look.
• Surface-mount raceways/cord hiders: Adhesive, paintable cable concealers stick to the wall and organize cords without opening the wall. They come in one-cord and larger multi-cable sizes with connectors for corners.

Not mounting a TV? A floor cable cover or a cable management box can help organize power strips and reduce clutter around media consoles.

Match the raceway size to your cable bundle and room for future adds:

1. Measure the bundle: Gather the cords you’ll route together and estimate the bundle’s diameter. A simple way is to tie them loosely and measure across.
2. Check internal dimensions: Compare your measurement to the raceway’s internal width/height. Pick a size that’s slightly larger so cables aren’t pinched.
3. Plan for growth: If you might add a soundbar or game console, choose a larger, multi-cable channel versus a slim one-cord track.
4. Consider connectors: If you have corners or transitions, make sure compatible elbows and couplers are available in the same profile.

Many cord hiders are low-profile and paintable, so you can keep a clean look without sacrificing capacity.

Adhesive raceways make it straightforward and renter-friendly:

1. Plan the path: Sketch your route from the TV to the outlet. Dry-fit channels and connectors (straights, inside/outside corners) to confirm lengths.
2. Prep the surface: Clean the wall with isopropyl alcohol and let it dry. Smooth, dust-free surfaces help adhesives bond.
3. Stick and press: Peel the backing, align carefully, and press firmly for 30–60 seconds. Use painter’s tape to support long runs while the adhesive sets.
4. Load cables and close: Lay cables, maintain gentle bends, then snap on the covers.
5. Paint and removal: Many covers are paintable. For future removal, warm the adhesive gently and pull slowly to reduce paint lift.

Separating power from low-voltage is the usual approach:

• Use an in-wall power kit: These provide recessed power behind the TV and connect to an existing outlet. Avoid fishing a detachable power cord loose in the wall.
• Choose in-wall rated cables: For HDMI/Ethernet, look for in-wall rated (e.g., CL2/CL3) as recommended by manufacturers.
• Work carefully: Turn off power at the breaker, locate studs, and avoid plumbing/HVAC. A hole saw attachment in some kits can help create clean openings.
• Mind bend radius: Keep gentle bends on HDMI and data cables to reduce signal issues.

Local codes can vary. If you’re unsure at any step, consider consulting a licensed professional.

You can expand most surface systems and tidy new cords without starting over:

1. Match the profile: Measure your existing raceway’s width/height and pick add-on channels in the same series or profile so lids and connectors fit properly.
2. Pick the right fittings: Look for straight couplers, inside/outside corners, and end caps to extend or branch your runs cleanly.
3. Blend the look: Choose the same color/finish, or repaint paintable covers for a seamless match.
4. In-wall additions: For more low-voltage lines, add compatible pass-through plates or grommets as needed.
