Disappointment
If you are using a 100x100mm or 75x75mm VESA mount and once you have adjusted the position of your screen, it is perfect.
Otherwise:
- The three vertical rotation axes are not parallel. To put it simply, every time I change the position of the screen significantly (except for its tilt), I have to correct the horizontality. And this is not a trivial matter, you quickly find yourself with more than 2cm on the width of the screen.
- The adapters to switch to a screen with VESA 100x200mm fixings are clearly deficient. Once mounted, they form a deformable parallelogram that makes the screws turn when you want to correct the horizontality or switch from landscape to portrait. In addition, you lose a lot of rigidity, which is particularly unpleasant when you adjust the tilt. I had to make my own adaptations to get a correct result.
