It doesn't work with this model. I have installed 1 monitor downstairs and 2 upstairs in our company. The work monitor at the bottom and 2 monitoring / information monitors at the top.

I have 3x 24" curved AOC screens mounted together.
Therefore, 2x 27" should not be a problem.
The 27" could certainly be stacked on top of each other, but I see this as critical, as the lower two screens will then be relatively close to the table.
The system is rather unsuitable for this.
