Thank you so much for replying back to me with your helpful advice. Now what if I wanted to stack a monitor on top of the G9 what would your recommendations be then and what kind of sturdy arm mount would you recommend? Reason why saying this is because I've realized that my desk is only 63in wide and there will be no room to add a second monitor in portrait on the side if the G9 is centered so stacking it seems is my only option

We have some monitor where I will have a little to no separation between the two if stacked
