I've got 3 PG42UQ's and use these stands for the two side monitors attached to my desk, with the center monitor attached to the wall behind my desk:

VIVO Aluminum Ultrawide Monitor Stand, Classic, Fits up to 49 inch Computer Screens, Single Articulating Pneumatic Arm, C-Clamp and Grommet Desk Mount, Max VESA 200x100, Black, STAND-V100H

And then I purchased these brackets to spread the load out across more of my desk as it's made of pretty basic particle board:

Edit: forgot to mention that I had to buy these things to make it fit the vesa size:

hth!

you will likely want to get a plate like this if you want to drill through a particle board desk :)

I'm not sure if Amazon basics has a compatible steel plate, but that's what I would use. I've used it on a glass tabletop with dual monitors and I knew someone who used it on a wooden tabletop. For reference this is what I am talking about: Monitor Mount Reinforcement Plate. You will have to find a compatible one for your monitor arm.
