I've been developing for 30+ years and I honestly don't see much of a productivity benefit using multiple monitors. I work differently when I have them, but not necessarily more efficiently. I find the head moving required to use multiple monitors more annoying than just alt-tabbing between windows. The only major exception is if I'm doing intense UI or visualization work and I want to see my code and the output at the same time. But even then, most of the time I can just resize my windows on a single screen. Different strokes for different folks and all that, but, anecdotally, having been tech lead for various sized groups as well, I never saw a performance boost when people got the multiple monitors they always wanted, either. I think part of it is that I find building a mental space of what I'm working on is the most important thing, and having tons of screen real estate acts as a replacement for that and thus goes against it, ultimately causing me to perform worse.
