The range of movements depends on the number of hinges a wall mount uses. The more the number of hinges, the more the movement the wall mount offers. But more hinges also mean added building costs. Thus, as a general rule, the more expensive wall mounts provide a more comprehensive range of movements.
Additionally, the angles of movement a hinge offers also vary. Typically, +/- 45-degrees the most for a tilt angle, +/- 90-degrees for swivel, and 360-degrees for rotation.
