Once the TV is hung and initially secured, make final adjustments. Use a level to ensure the TV is perfectly horizontal. You can then use the mount's fine adjustments to pan, swivel, or tilt the TV to achieve the optimal viewing angle in your room. If your mount includes cable management clips, route your cables through them for a clean and organized look, concealing them behind the TV and mount. After all adjustments are complete and you are satisfied with the positioning, fully tighten all securing nuts and bolts on the mount using a socket set to lock the TV into its final position.
