> I know 0 people who use more than two monitors on any OS.

Three in this thread alone, and shifting the goalposts from “studies show it is bad” to “I don’t know anyone with multiple monitors” or “It is tiring to move your head around all the time” indicate you are not debating this in good faith, so I am done with this chat.

Have a great day!

Every person in my company has a laptop screen and two monitors on their desk, including devs, product, managers, infra, admin... Literally everyone. The only people who don't use them are senior leadership because they're rarely at their desks.
