Troubleshooting
If you encounter any issues, refer to the following common problems and solutions:
- TV is not level: Use the level adjustment feature (±3°) on the TV bracket to fine-tune the horizontal position.
- Mount movement is stiff: Check for any overtightened bolts on the articulating arms. Loosen slightly if necessary. Ensure no cables are obstructing movement.
