This is not an issue of preference. I would ask that you watch the video recordings in my original post, where I demonstrate that the hinges are not just looser than my preference. Both sets of hinges I received could not physically hold the screen in place, while completely stationary on a table.
That’s why it’s so absurd to me that customer support suggest that I buy the 4kg hinge as the solution to my problem. Because it’s essentially an admission from them that the 3.3kg hinge does not meet the basic requirement of holding the screen in place.
