To those with 2+ monitors on your machine: What's your use case, and how much does it actually boost your productivity?
I'm mainly curious about software developers here, or anyone else whose computer is somewhat central to their life, be it professional or hobbyist.
I only have two monitors—one directly in front of me, and another to the right of it, angled toward me. For web development, I keep my editor on the main screen, and anything auxiliary (be that a dev build, a video, StackOverflow, etc.) on the side screen.
I wouldn't mind a third monitor, and if I had one, I'd definitely use it for log/output, since currently it's a floating window that I shuffle around however necessary. It could be smaller than the other two, and I might even turn it vertical so I could split the screen between output and a terminal, configuring a AutoHotKey script to focus the terminal.
I have four monitors. Two slightly angled directly in front of me, one angled on the left and a small 10 inch directly below my two main monitors that I use specifically for discord and my friend's chat app he's working on.
Why two directly in front of me with the split in the middle? I only have to shift my head slightly to move between the game I'm playing and whatever I'm watching.
But it's more useful when I'm working on pixel art because I can have my drawing on one main monitor and my reference in the other while having a show or stream on the secondary angled on my left and chat stays on the small monitor.
As for if that helps productivity, I have no idea.
