I've been using just one monitor for the last two years and never once wanted to go back to multiple monitors. I used to have two external monitors and it was always frustrating to dock/undock and re-arrange my windows. That was why I transitioned. But I've seen no reason or negative impact on my work to drive me to return to multiple screens. HackerNews often talks about how task switching and multi-tasking negatively affect focus. I wonder if those same people think multiple monitors contribute to either of those. On my screen I only ever have one window; it feels more intentional. On three screens I had email and teams on one, a browser on another, and my IDE on the third. Surely that's more distracting, no? Initial Google results seem to sing the praises of multiple monitors. Am I truly unproductive on my one screen or have others seen the same benefits? How can "productivity" even be quantified?
