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.
Independent IT Contractor: I have a 4-wide 1080p screen setup. I keep Slack/Teams on one screen, the semicircle setup means I can only really look at 3 at the same time. I upgraded from 3 screens because I kept having to juggle windows around while troubleshooting someone's webserver.
Also used this setup when I was really heavy into FFXIV- I like having wikis/alerts open and visible, so one screen for that, the game, discord, and then the last one was just for youtube/netflix.
