Okay look, I have it, I set it up and have the instructions. The screw turns both ways, one way tightens it and increases the resistance and one way decreases the resistance. If it is fully tightened the damn thing doesn’t move at all and points up to the ceiling (not really, exaggerating). If it is fully loose it balances with a slight upward tilt as you describe.
Unless you’re suggesting that I force the monitor down with one hand against the tension of the spring and torque it down to max to get it to stay. Which goes against every indication of the instructions and way that the rest of the arm is adjusted.
That could be the way, I don’t know
