I noticed that, too. I thought it was supposed to swivel vertically, not just horizontally. I also had a few other problems. The monster allen wrench doesn't seem to tighten the assembly but rather just turn the whole thing. The only way to stabilize the assembly is to tighten the large upper nut. But as soon as you swivel the screen the nut loosens. And after you put on the newer Hansshow fascia you can't get to the nut. Plus the fascia cover just doesn't fit very well. It's way too tight in the rear of the assembly (nearer to the passenger/driver compartment. This poorly designed fascia cover is probably why several installation videos complain about the big gap where to facia is suppose to grab on to the underneath part of the upper dashboard cover. And that extra piece of plastic that is included with the kit does not help at all. The cover is just poorly designed. I had to cut a hole in the top of the cover to access the nut. Then I designed a formed piece of plastic to cover the hole and screwed in place with some 0-80 screws. I also replaced the big nut with a self-locking (nylon insert) nut. (See attached M3_1 through M3_3) Unfortunately, It was too long (thickness), so I had to cut about 1/8" off the end of the nut so the nylon part could grab on to the screw. The only way to cut off the end of the screw is if you have access to a metal cutting lathe, which I assume most people don't have a use for. I also tapered the contact face of the self-locking nut (more conical) so it would allow the assembly to rotate more easily. Needless to say, this is an awful lot of trouble to go to for a poorly designed screen swivel. Hopefully, one of the other manufacturer's versions has a better design. (I won't even go into that ridiculous mounting system for the temperature sensor (See attached M3_4 and M3_5). The original tabs break off, so I formulated a modified mounting system.)
