I do 'light' software development for a SAAS. I use a single ultra wide. It has PiP settings so I can display my personal if I'd like while working, or have everything displayed on the work side as a triple window or dual window setup. The flexibility is great but overall ultra wides are still niche and a general pain in the ass. Good luck getting any game to run more than 90fps when you're pushing a 5k resolution and 240 refresh.

Backend dev. I have an ultrawide (like two monitors in one).

Sometimes I need to test the full stack and need a lot (8+) terminals. I try to tile them all on a separate virtual desktop.

Most commonly though, I center my main application and can have two smaller, peripheral applications, one on each side.

When doing full stack, I need a browser, IDE and two terminals, tiled to give more space for the browser.

Not a software dev but tech is central to my life.

3 monitors for normal use

1 - personal streaming, video meetings

2 - remote business desktop access, main personal browsing window

3 - online chat presence window, personal email client, other

3 monitor gaming

3 monitors for racing simulators and any games that support it (which make sense)

Single monitor gaming

1 - Game related content on left 2 - Game window in center 3 - Game related social media or streaming

3 monitor home labbing

1 machine or app per monitor Triple monitor stare and compare windows GUI / CLI / Monitoring system interface

I didn't realize how extensively I used my monitors until this exercise. Feel better about the spend and space tax related to it.

I use multiple monitors for audio production. My use case is a bit weird since I code Csound and use a DAW, which is unconventional. It's great for having the DAW up on the 4k, and some code or docs or both on the 1080p, 144Hz. If you didn't guess from the mixture of resolutions and frame rates, I've got gaming covered as well.

Truthfully, the 4k probably has the real estate to do all that on its own, but it was the last monitor I bought and why not use the other? I'm too lazy to figure out a setup to hook up the other 1080s I have lying around. (And don't need the space in any case)

Not a dev, but I have 3 monitors on my rig that I use for work and play.

A 24" 1080p as my main monitor for stuff like games or Blender, a smaller 18 and a half inch 720p for secondary stuff like Firefox, Discord/TeamSpeak, and monitoring Cura when the 3d printer is going, and a 21" 1080p Wacom on a monitor arm. The Wacom is kinda outside my field of view unless I'm actively using it, so most of the time it just has a performance monitor running so I can see what's hogging my resources. Having Spotify on there is nice though, the touchscreen/stylus makes running it quick and easy.

Software dev here, and I'm pretty confident that 4 is the ideal number, as long as you have window snapping to split them in half:

Left (inputs): half current ticket, half whatever documentation you need

Main (work): IDE, half test code, half actual code

Right (outputs): half terminal, half web page (frontend) or postman (backend)

Bottom (comms): Smaller laptop screen dedicated to slack / email

Teacher here. I have my laptop (16”) and an ultra wide (34”) on my desk, and a projector behind me. I keep my email, attendance, and calendar on the laptop screen.

On the ultra wide, I keep my grade books and various spreadsheets, since more width makes it easier to see more data, and I have my daily agendas/lesson plans. Again, more width makes it easier to see the whole week at once. I keep that fixed to 2/3rds width of the screen, and the other side is reserved for Spotify at like 1/6th width

The projector is used to show the daily agenda, videos, instructions, etc. I very frequently screencast my iPad to the projector, so I can fill out worksheets on it with the class and they can see me write or circle things.

I can’t even fathom having any less screen real estate now. I gotta be able to see it all at once!

I have 2 monitors. My primary is ultra wide for gaming and the secondary is discord, Spotify, etc. so I can view messages and stuff without leaving my full screen game.

For work? I just use my Mac monitor like a neanderthal. Idk why but I don't really find multiple monitors helps me work faster.

Loads of data sciency stuff - one monitor for normal text editing/terminal work, another for accessing remote environments, and a third for a combo of work comms and music.

When not sciencing, I won't lie, there's a lot of Path of Exile with PoB on one screen and a podcast on the third.

I have 4. My main and second are 46" each, the 3rd. is a 27" in normal/landscape, and the 4th is a 27" in portrait. The main is in front of me, the 2nd. is to the right and angled toward me, the 3rd. faces me at 90 degrees from the main, and the 4th. Is mounted above the 3rd. I used them originally for streaming and all of the windows I had open to monitor everything at the time as well as the game I was playing. Now I find them useful for working on projects, watching videos or movies while I play a game, and working on multiple spreadsheets at the same time. The one in portrait is especially helpful when I'm looking at a season's worth of a scheduling spreadsheet.

At work I have two monitors. One for input (my IDE for programming) and one for output ( the browser to watch changes for my react app).

At home I bought the 49 in. Samsung and have three monitors. Third is normally the log output.

Two monitors is the absolute minimum, but I think three can be very useful.

On one, I have reference materials, on one I have code, and on one I have the application I'm developing. I think it makes for a pretty good workflow.

Not an IC anymore but my workhorses for the better part of 13 years were 13” laptops. Nice and simple. I don’t get the multiple monitor thing honestly.

I have three identical monitors in a row. Primarily I use the center one, for productive work and gaming, but often I'll have something up on the second screen that I'm working with as well. It's more rare that I actively use the third one, but some tasks have more than two or three windows and now I can see all of them full size at once.

I've occasionally used them as a single ultra wide screen for gaming, but since then I've gotten an hmd for VR and that is better.

Not a software developer, I just do QA on written documents, and being able to have 3-4 windows side by side is really nice. I usually have 1-2 tracking spreadsheets open on the left, and two documents side by side on the right. I use a laptop at work as well, so sometimes I'll leave it's screen on for email and Teams chat so neither interrupts my work.

Single large 48” 4K gang here. It’s like 4x 24”+ 1080p monitors in a square with no bezels.

I have two monitors plus my laptop screen. I keep my IDE open on one, my browser open on another, and my terminal open on the last one. It may not boost my productivity a lot each day, but saving maybe a minute every hour adds up.

It’s much easier to move my mouse to the left than it is to switch windows. When I’m not at home and I have to code on just my laptop, I do miss the extra monitors.

I like the single ultrawide, maybe with the laptop screen for a meeting app. Two monitors just feels like a compromise and for a little extra you can just remove the border entirely

I'm an engineer (a non-IT engineer) and have 4. There is so much ensuring consistency between drawings and documents. I'd like 5 (including the inbuilt one) but graphics card on my high performance company laptop says no.

At least one for file explorer, then other three could be pdf editor, or word, or excel, or internet browser.

I regularly have 4 drawings open, plus another reference, plus windows explorer for file management.

It's never enough. I could totally do with more than 4 screens, I'm already squeezing multiple drawings onto one monitor.

What is a rainbow computer?

I have two monitors but I do all my work on one the other is completely separate. Plays YouTube all day so that I have background noise to work with.

Four monitors plus the laptop screen. It’s…a lot visually, but my productivity is significantly higher than when I only had two and the laptop screen.

They’re arranged in a square so clockwise from top right:

1. Work entry screen - this is where I’m typing a lot

2. Reading screen - this is the general source of what I’m working on

3. Outlook - I’m fully remote, Outlook is life

4. File folders - I work mainly with two or three folders all day so it just makes sense to have them uncovered

Laptop - Teams!

Of note, I use a ton of keyboard shortcuts and have generally optimized my workflow so I’m not hitting the mouse nearly as often as my coworkers. Having Outlook and Teams each have their own screen means I can keep them open and see what’s coming in while still working on my stuff on other screens. Final thing I’ll say about the arrangement, because you’re probably visualizing this making for a good gaming setup, no it wouldn’t because of how the screens are placed.

No matter what, get yourself a mirror. I don’t like people suddenly appearing by me, and since I’m using noise-cancelling headphones with music/podcasts 40+ hours a week, this keeps me from jumping out of my skin.

I'm more productive than anyone else on my team, and would argue more productive than the majority of people in my whole department. I use a single 28" monitor.

I’m a video editor with two 27” monitors. One landscape the other portrait. I used to use both monitors for premiere but found moving the mouse around that much annoying so I condensed all my panels into one monitor and use the portrait one for notes and communication. I feel like I could go back to a single monitor system in the future but I like having two

I use two monitors: one in landscape orientation and the other vertical. I usually keep console windows in the vertical one and that's where I write code. Typically its code editing on the left side and a few console windows with compiler/server output on the right. Landscape gets firefox web UI: current app, time clock or notes window.

So that's two workspaces. I have additional monitor-level workspaces I can flip to: #3 for chrome (google products), #4 for signal/thunderbird, #5 for keepassxc, #6 for an additional set of console windows for a second project, or for other things like system upgrades and etc.

I run pretty much the same workspaces on my laptop with only one monitor, the main difference is having to flip back and forth more. Its a little more mental overhead. On the dual monitor rig I like the vertical orientation for my code window, I can see 2x the amount of code at once.

Overall I'd say the productivity boost from multiple monitors is low to mid. Its nice to have but I can still get work done on a laptop screen. That said I do most of my work on the dual setup.

I have three monitors. Middle is an ultra wide with the tests and another window of stuff (the app, data, etc). Right is a 1080 with docs. Left is a 1080 with the code in question.
