Mounting cantilever monitor on plasterboard walls

[MatteRB26]

Hi, I have two cantilever monitor mounted that I used in brick walls at our old house (we've just moved into a brand new build) and these walls are plaster.

I have two monitors that I wanted to mount, one in happy with because it's flat against the wall, however the other needs the arm to be extended to use it properly.

Will I be alright finding some kind of plaster toggle bolt or something to mount it? The mount is two vertical screws so the weight will be distributed vertically. I could get lucky with finding a stud.

Otherwise I'm tempted to just buy a dual arm desk clamp.

Perhaps I'll take a look at where the studs are then, and maybe get a couple of those anyway, the two screws feels less substantial without solid walls.

A lot of people I know use Gripit's as well, 5 of those each should help too if I can't use the studs

Alternatively I could consider a dual arm desk clamp mount instead? My desk is 36mm pine timber board (2x 18mm stacked together around the edges) so it should withstand the clamp. If it'd be too much weight in one point I could get two, or stack some more wood to give a thicker surface to grip onto.

Only thing I'll say is, screwing into studs in new builds is different to older properties. New builds are all metal stud so you'll need self-drilling screws.

I'd probably go with a bit of ply wood with four or so hollow wall anchors into it to spread the load and then screw the wall mount to that.

Could this be why my in laws stud finder just goes nuts on the walls? I'd find a stud and it would beep at me all the way up/down without letting up.
