How do monitor arms keep cables from becoming a tangled mess?

Good monitor arms route cables along the arm length through integrated channels or clips that keep power, video, and USB cords bundled and out of sight. The cleanest designs use a hollow-tube arm where cables pass through the inside entirely. For dual or triple monitor setups, look for arms with large-capacity channels that can handle multiple cables per run.
