i got this ultrawide 1440p from work and it's ridiculous side-by-side with my main monitor.
however i can't switch to it exclusively, because it's only 60hz.

i've got an amazonbasics ergotron mount for my main monitor and it doesn't have the vertical freedom to stack, so i think i'd have to buy a different mount to stack them.

or i can just suck it up and have a huge monitor side by side with my main one.
