Virtual desktops, multi monitor and tmux allow me to go full ADHD, everything open at once, multiple projects on different desktops with like 5 windows open

Bonus points when I've got multiple terminals connected to the same tmux session because I forgot I already had it on another desktop or wanted it split with something else

My home setup is an ultrawide and a 1080p monitor. I find with tiling and virtual desktops more than that is surplus to requirement (even the 1080p monitor usually just has a browser open)

I only have 1 ultra wide monitor. It's slightly less screen space than 2 monitors, but it's enough, and I like the simplicity of it.

Software engineer. Work from home and I use the same monitors for work and personal.

Usually for work, I have code in the middle, specs on the left and the app on the right. When I’m not using specs, I have Spotify or video related things on one monitor.

For personal use, gaming is done on the middle monitor. Sometimes I have Spotify on the left, video on the right. Sometimes it’s a mix of discord/video/spotify on the left and right monitors. Sometimes I have a hockey game on one monitor and YouTube on the other.

Middle is my main.

It’s not often I don’t have something on all monitors.

I have three. Left for email, right for Teams, middle for whatever I'm working on. Then I cover up Teams and Email (in that order) when I need to see multiple things at once (e.g., a second instance of VS or SSMS or a browser).

I have an ultrawide as my main monitor and a regular wide screen monitor floating above it on an arm. The main thing I need all that space for is running ttrpg games, honestly. Roll20 or some other vtt open on one side of the ultrawide, then other side has rule book pdfs, enemy stat blocks, notes, etc. The top monitor has discord for chat as well as everyone's webcams.

But outside of that it's nice to have a browser or discord visible on one screen while playing a game on the main display, but you could get by without it.

I'm a dev. Right monitor has my browser, center monitor has my editor, left monitor for everything else (terminal, dev tools, file manager, http client etc)

Designer/animator, Mac, either two-screen app setup/workflow (ie editing, 3D, etc) or an easy way to have 2 related things going (ie, brief + job, reference + project, etc).

work and play at the same time. discord, weather map, cameras, password manager, firefox, chrome, citrix etc. also use a tiling manager so much easier

One additional vertical monitor for e-mail, papers or documentation is great.

I do fiber optic tech support

Left monitor is for account software (includes customer info, ticket manager, etc)

Middle monitor is email, browser (most of our management tools are browser based), and putty

Right monitor is ms teams, notepads++, and a softphone app

Code, editors, terminal, and most browser tabs on the right..

Calendar, Slack, some more browser windows on the left, sometimes some debugging tools.

Third smaller screen off to the side for media if I want to throw on something in the background.

For work, it's usually IDE on the right (my larger screen) and a live build of the thing I'm working with on the left (a laptop screen). Though it varies a lot throughout the day. Primary screen gets the app that needs most scrutiny, small screen gets auxilliary things like passive communication apps or reference materials.

For home use, where I have two monitors of equal size, it's usually Discord on one screen and a web browser on the other. Comms on the left and active task on the right.

I don't see a use case in my workflow for a third screen, especially not one that is a weird size or is in portrait orientation. But if one was simply bestowed upon me, I'm sure I'd find something to do with it sooner or later. There was a time where I though two monitors was overrated, I'm sure I can adapt my opinion again for 3+.

I have a central monitor in landscape orientation which is where my IDE lives. Then a monitor on the left in portrait, which has the bottom quarter or so dedicated to work chat, music controls, and the browser developer window, then the rest of it is a web browser for documentation. On the right is my laptop screen, which is used for more documentation and watching TV shows while I work

Two screens and a laptop screen, could find use for more. I find myself shuffling things around depending on what I need, but most commonly I have the left screen split between notepad++ on one side for any notes keeping, and either documentation I'm reading, documentation I'm writing, a browser I'm using, or something such. Whenever I need to compare text files, notepad++ gets to take the whole screen.

On the middle screen I usually have the remote desktop or VM I'm working on at the time.

Right (laptop screen) is usually reserved for Outlook and Teams.

• Left (horizontal) - communicators, btop, Spotify.
• Middle (horizontal) - browser with GitLab, terminals and editors, main development in general.
• Right (vertical) - browser for googling and docs, terminals for tests / logs / whatever I want to see at the same time as the editor, Obsidian for notes.

Anything less than that will completely ruin my workflow. I'm even trying to come up with a feasible way to fit a fourth one.

• Left (wide screen): Teams and Jira
• Center (Ultra wide screen): IDE, file browser and other main stuff
• Right (portrait): Terminal and ocational documents

• Left (vertical) - Notesnook (or whichever knowledge management system I'm on at that particular moment), Signal, and Slack all tiled so I can see them all together.
• Middle (horizontal) - IDE.
• Right (vertical) - Browser.

This works well, but I'd enjoy another monitor for Spotify or, more likely, so I could make all the terminal, debugger, run, database, etc from my IDE full-blown windows on the fourth monitor.

Music production. Left: tracking and editing window. Right: mixer and plug-ins

Left reference, middle work, right email/IM

I operate a ZLD plant processing blowdown for a combined cycle power plant. I have two computers at my desk. The left computer is for email, data entry, training, and monitoring a few power block and BOP things via PI; this is with two monitors, one above the other. The right computer is for operating the plant directly and monitoring native trends; this is with four monitors, 2x2.

I'd say I don't need more than this, but I would feel some pain if I had fewer. I would love to have another monitor or two to display camera feeds, but my plant never figured out how to get the cameras set up so we just climb ladders to look into sight glass windows once in a while. Or I might be the only one who actually bothers with that lol. Really the 4 monitor rig could and probably should be replaced by a big 4k screen if the software supports windowed instances instead of full screen like we have been running. It wouldn't surprise me if this POS program can't do that though.

My work setup has two monitors in a horizontal layout.

Left (in front of me) contains the main stuff for my task at the moment. That's where my meeting app goes as well so I can look straight at the webcam during meetings.

Right has the supporting stuff, reference docs, IM just in case I need to be pulled away for some critical issue, etc.

At most, I can work with three monitors for increasing productivity in terms of screen real estate. More than that would be a case of diminishing returns for more physical space taken.

2 is the bare minimum for work as a sysadmin.
3 is better, then I can dedicate one to communication (email, Teams, softphone), one for documentation and one to actually work on. I could see 4 being useful if you work both locally and on terminal servers but I've never tried it.

The thing I've always noticed about getting more monitors is that you never really think you need one more monitor until you end up getting one somehow. After that you start getting used to the extra space and it feels wrong to go back to having less. When I originally had one monitor I was just used to that and didn't see anything wrong with it. Once I got two monitors I again felt good and got used to it. It was really nice to be able to watch stuff while playing games or have Unity and Visual Studio on separate screens at the same time. Eventually I got a nicer monitor and decided to go up to 3 monitors which again felt really nice and I found uses for all 3. That's where I'm at now and I don't have plans to get anymore but if I ever got a newer monitor there's a good chance I would end up giving 4 a try cause why let one of my older but still good monitors go to waste. And I imagine I would still be able to find uses for the extra space. I feel like at some point there is a limit but at least so far every time I've gained more monitor space even when I'm not sure what I would use it for I always end up using that extra space for something.

I have three. The third doesn't really boost my productivity much, I have it vertical just to show my file browser because I open and switch through different files quite a lot. The other two are to show the actual files I'm working in or comparing.

Scientist here, a lot of my job is writing texts with references to other literature of the field, or reviewing such texts (or PowerPoints). Main screen has the document open, the other is actually in portrait format and has gazillions of open pdfs on it that are relevant to whatever I'm working on. I had to get this setup for working from home because productivity dropped immensely with only one screen.

not a software dev, but a linux user and a stout technology enthusiast.

I have 3 monitors setup on my primary workstation. Two landscape in a stacked arrangement, it's just tidy and works well enough for a secondary media display, organizational monitor. And then my third is portrait for anything i keep long term tabs on, chat programs, music player, system resources, etc...

I recently switched from KDE to i3wm, and i find i need inherently less monitor. i3wm does all the sorting organization and bullshit i hate for me automagically, it's perfect for opening a terminal to check something, or work on something real quick, and being able to have one static window, and two tabbed/stacked windows on one monitor is HUGE. Super nice for terminal breakouts with a browser for documentation. If you're ever balls deep in a config and testing shit actively, you'll immediately understand how much of a godsend it is.

Anyway, floating window managers are dead and anything shipping a floating window manager is a dead product on arrival.

Author (not very successful, but still).

Main screen is for writing and editing. Second screen holds notes, maps, etc for reference as I write. If I'm editing, second screen usually has a music player going, along with notes about changes needed.

I can't say it's necessary, but the second screen really does help keep me focused better. Instead of having to switch windows and then come back, or have windows stacked up and have to move things, being able to just glance at the secondary screen is awesome.

Like, I'll have my name list up, a map of the area, and the notes for the chapter up on the secondary screen, with a fourth window tiled with any extras needed (like quick sketches for things). It's a mid sized monitor (27 inch iirc), so everything is readable with my reading glasses but it doesn't hog desk space. The main monitor is a 31 inch where I can have librewriter up and sized to where I need it, with a notepad window to the side for copy/paste usage or quick sections that inspiration hits but it isn't the right section to just enter it into the working file.

Compared to the single monitor set up I used to have, it saves me time, and *more important) allows me to stay in flow state better, which means better writing, with less editing needed later. I can, when I'm actually writing rather than trying to write, double or triple my output compared to before.

Gaming: I have a game that has tons of third party software that tracks game elements real-time that are far easier to read, contain more information, and more readily understandable than any in-game menu. So play the game on one monitor, have the apps running in windows on the second one.

3D design. Have the work window open for maximum real estate on one monitor, have pop-out menus and tools on the other for things that maybe don’t have hot keys or shortcuts assigned. Also, a small browser window for “how do I” question when I hit a roadblock.

2 27” 4k monitors. I do 98% of everything on the main monitor. The screen to the right contains a few sticky notes (I use Zhorn Stickies) and a Ticktick widget with all my tasks for the day. When I start up Obsidian, I have a saved Ivy Lee list that appears in a spot on the right side monitor as well. It’s just basically quick-glance scrap space.
