Two 4k 32 inch monitors and docked laptop screen.
One monitor directly in front which holds code, research or video call.
One monitor to the right mounted vertically and angled towards me that holds a terminal, notes/email/jira or reference documentation for whatever I’m doing on the middle screen.
Laptop is to the left of the main screen and has slack open.
I’m big on tilling window managers, so I tend to do a lot of flipping between workspaces rather than apps, in my mental model. I’ve gotta use a Mac for work which sucks for tilling, but I can mostly make it work.
