Everything is fine, except for the monitor stand (not the base, just the 'arm') which I have not yet been able to use properly; it seems that the part of the 'arm' which is attached to the monitor must rotate 90°, but there are two cases: either I am not able to rotate it (with the consequence that the monitor cannot stay in its natural position) or that arm is designed to support its monitor in places such as a public establishment, where the total support (base + 'arm') should not be kept on a desk, but on the wall: to understand each other, the base installed on a wall and the arm connected accordingly, so that the monitor can be (almost) parallel to the wall.... I don't know if I have explained myself...
