In assembling a metal plate is attached to each monitor, which is hooked into the holder and then screwed. These plates have both the 75er, and the 100-hole. Caution should be exercised when the monitors have an in-depth 75er VESA hole, because then it can not be easily screw the plate. I have the problem with the VESA Secomp adapter (also available at Amazon) solved by I've screwed with the supplied disk via bolt with nut. Here you should make sure to use countersunk screws so that no gaps arise problematic. Furthermore, only 8 screws are included, but in principle sufficient for the monitors.
The monitor can be rotated on the articulated arm as a pivot monitor, but only for small monitors might make sense because larger monitors will not fit over each other.
