I've been employed in the same company for the past 16 years as a systems analyst. Over the past 10 years or so I've always had 2-3 monitors (4 - 5 at times when I got real ambitious). Recently, I downgraded to a single 32" 1440p monitor and it feels as if I'm able to focus more intently on what I'm working on.
I'm not saying it will help everyone, but it's really helped me regain focus. So many distracting windows are now gone. No longer keeping tabs on Discord/YouTube/etc while working...well, not as much at least.
Has anyone else noticed an increased work efficiency when 'downgrading' to a single monitor setup?
