This is the most direct fix available, and it works because it’s specifically designed for exactly this problem. A cord raceway is a plastic channel that sticks to the wall with strong adhesive, with a snap-on cover that hides the wires running through it. Before applying one, clean the wall thoroughly with rubbing alcohol, since adhesive rarely bonds well to a dusty or oily surface, and cut the pieces at 45-degree angles wherever the cord run changes direction, for a cleaner, more finished look. Painting the raceway to match your wall colour beforehand, rather than after installation, makes it genuinely disappear once it’s mounted.
