Screens, believes & productivity
There are some topics which can can cause a very controversional discussion when you put software engineers in a room. Vim vs Emacs. Favorite Linux distribution. Generics and static typing. But one thing a significant amount seem to agree on is that a multi screen setup is a requirement to be productive.
Over the last 24 years I looked at many computer screens. Different kinds, different sizes and obviously a different amount of screens. And for a long time I would have agreed that you should run a multi screen system to increase your productivity. There are blog posts, studies and anecdotes all over the net advocating for multiple screens.
My first dual screen setup was a mix of an 17" and 15" CRT. Later on 19" and 17" LCD. At some point dual 24". With the 2015 MacBook Pro I moved to dual 27" and when upgrading to the iMac Pro to triple 27". But something changed for me. I actually got rid - read: upgraded my parents offices - of two LG Ultrafine 5k and now only work with my 5k iMac Pro.
The most important part in the above paragraph is for me. I did not conduct a scientific study. I did not run multiple tests. I reduced my setup one screen at a time, working two to four weeks with a setup to see if anything changed. Your mileage may vary.
The physical change is pretty obvious: I do not move my head all day. At some point I used anything but the iMac as an "informative" screen in my peripheral vision and when something happened I moved the window to my main screen. Not moving my head a lot during the day is actually more pleasant - who would have thought?
From a productivity perspective I made some changes to account for the lack of a second and third screen:
I never kept email, chat, etc open all day to immediately react to every single message. Before I had them sitting on the left screen but simply did not look at them, so my availability is the same. If I am being pinged or get a notification I can choose to open the app or move to the virtual screen with one click. I can catch up with the random and music channel at any other time, I do not need to know that there is activity.
I often had a web browser with documentation open on the right screen. Now I mostly just Command-Tab to my browser, read what's relevant and Command-Tab back to my editor. It is rare that I need the editor and documentation at the same time, but on 27" 5k I can fit both next to each other if I really need it. Thanks to Magnet this is only a matter of a few key strokes.
I have my 12.9" iPad Pro next to my iMac and played a bit with Sidecar, but I mostly use it to move apps to the iPad when I want to use the Apple Pencil. Initially I thought it might be a nice compromise if I need some docs open, but I find it more comfortable to rearrange windows than moving my head.
Overall 27" simply proved to be large enough to comfortably work with a single screen setup. Having a multi screen system is something I setup out of habit. And I believe with smaller screens this still makes a lot of sense. But hardware evolved into large screens. (A single 34" slightly curved widescreen might be the sweet spot - not a lot of head movement, no bezels and a little bit more vertical space to fit a small window in for some convenience and a little bit less rearranging.)
Why am I writing this post? To enlighten people on how to be productive? To advocate minimalism? To kick off a long study of productivity related to size and number of screens? Nope, nothing fancy or hip. Just a reminder - primarily for myself - to reevaluate old believes and habits from time to time.
