Hello :)
I don't really get what this video's supposed to show. I got tilt issues with my monitor arm, so i'm looking here and there for a solution.
I don't see what the difference in you video between the start and the end, as it seems that the "tilt" is moving the same way.
Has the manipulation strenghthen it though ?
