ADHD

I agree with this - I've been steadfast in working on a single monitor workflow. Not only is it more ergonomic (pressing keys is less effort than moving your head), I find that it helps with focus too. I find that having more than 2 (or 3) windows open only provides distractions and sensory overload for me.

(Disclaimer: I'm not diagnosed with ADHD)

I have 3 monitors and sometimes, when I want to focus more, I turn off one of them and use the 2 remaining monitors for a single task, similar to what you do. So yes, I think it can help if you're only doing one thing.

Now, when I do many small things at the same time, there's no way I can focus unless I have all my monitors on.

I have never had a second monitor as I have speakers that take that space. Keeping my phone out of reach definitely helps.

Most of my coding happens on the monitor of an 15" thinkpad. No room for distracting stuff, atleast not visibly and missing emails or instant messages is way easier if they are just a single ping, thats drowned out by music, instead of a cascade of text scrolling by.

The big monitor is for less focused work or the odd day i actually want to look at multiple things at once to find an odd quirk happening in a bigger system.

I just bought that keyboard not long ago for traveling. Cute little thing!! Especially for the size of your setup :D

Not for me, I am "out of sight - out of mind" and on a regular day I need several tools (for example code editor, several terminal sessions and at least a browser session). When I've tried one screen, I can space out for a long time because I have to keep reminding myself to bring one of those tools to the foreground when I need them. I need to see all the relevant things in front of me.

I don't really use any social or leisure sites on my work set up; I use a separate computer for that, which makes it easier to do one thing at the time. At most I have some music in the background.

I'm a software engineer. One monitor for vim, one monitor for the terminal, one monitor for the browser. Somewhere in there is chat, which is how I do most of my work communication. I have to keep a lot of information in front of me while I work so I benefit from more monitor space.

The distraction tends to come from my phone, or more generally when my company does something infuriating and I can't think straight for a while.

I find that the key is what I have on my second screen. I'm pretty good at only putting stuff on my second screen that help me with my task. Usually a checklist. I've learned not to have anything that I need to monitor or will grab my attention.

I'd have to try it... But even then I'd use youtube's floating window on the corner just to keep watching stuff.

I think that experience is really going to depend on the individual. I like having a monitor dedicated to email/calendar. But I can certainly understand how it could turn into a distraction.
