Hello, I have this screen. I am very satisfied with it. Attention regarding your concern: the screen is heavy! I would not mount two of them on the same bracket. Then rather both separately with the enclosed wall mount. Another note: I have an Nvidia RTX 2080 graphics card with it: it runs at the highest possible settings with graphics-intensive games almost under full load, enormous heat development with one screen. So be careful with two!

The question is perhaps no longer so topical.
I had the same intention and found this monitor holder (unfortunately not on digitec.ch):

With a load capacity of up to 16kg per monitor, this should not be a problem.
The monitor has a Vesa 100 mount, so it should fit.

P.s. Another hint I stumbled across: the screen has no audio!
