Hoi - you can attach up to 3 monitors that are up to 32" wide to the monitor arm or to this Arctic...
The monitor you are linking to meets the VESA specifications (100x100) of the holder. With the weight (maximum load 30KG) and if you attach 3 Asus (9.3KG each) it will be correspondingly tight (you are then at 27.9KG without cable (3x DP/HDMI, 3x power...)...
As for the width: the Asus is 31.5" or probably just 32" - will be tight but should work - if you want to attach 3 monitors.
Also consider the tabletop where you want to mount it in terms of stability...
With 1 to 2 - Easy.
Hope that helps and LG

Hi, to answer this question, you can simply compare the monitor with the bracket in the specifications under "VESA wall mount type". Here is the type described for the monitor: 100 x 100 mm. For the bracket:
100 x 100 mm, 75 x 75 mm. So you have the option of mounting a 75mm VESA or 100mm VESA monitor. I'll let you calculate the weight yourself.
Hope this helps, small tip: you can often find information faster in the specifications than in the forums.
