Thanks a lot for the feedback! Do you know if the outside rotational part is it adjustable on-the-go, or does it rather require loosening/tightening of the screws? I mean the part that makes the monitor "face up" or "face down", e.g. here on the picture: https://euroelectronics.eu/cdn/shop/products/hqdefault_fec2e11e-701b-4ddd-a4ec-ba21e0bdab07.jpg?v=1587381905&width=1800
(It seems to require loosening/tightening, but want to confirm.)
