On the contrary, I have a 49" 32:9 monitor, and for a laptop it's wonderful. The support for a single monitor is just way better than any dual (or more) setup.

I can just connect it directly to my laptop, and it just works. When I had two displays I needed a docking station, and truth is most of those out there suck. Unless you go for the top models, and then you've lost all the money you saved on cheaper monitors. In addition you generally need a thunderbolt compatible dock, and that seems to come with it's own category of issues, assuming your laptop even supports it.

Also found ultrawide easier to configure hotkeys for windows management.

The advantage I've found with multiple monitors is the ability to independently switch the "desktop" that's showing on each.

I can have a desktop for coding, a desktop for reference docs and previews, another for working on non-coding tasks, one with general browsing, one for chat/email/calendar, etc.

I've not found a satisfying way (on Mac OS on my Macbook or with various WMs — Sway is my go-to) to quickly replicate this ability to have multiple task oriented sets of windows visible at the same time and make them quickly switchable without multiple physical screens.

How would you organise such a multiple display setup in sway?

I use sway on my laptop only, but Gnome 45 and macOS is easier for me, for now. When it comes to multiple displays. The best feature of sway for me is the ability to assign apps to their workspaces, and also assign hotkeys to these workspaces. So e.g. cmd+alt+e opens Files app (nautilus) and it’s always on its files workspace that I activate with cmd+e. Quite very useful for me. I almost never open windows tiled, very seldom that I have two at one screen.

So with multiple displays, I am quite unsure how to organise that, which logic to apply here. Maybe I alt-tab out of old habit, but it’s so much easier, cognitively speaking, comparing to remembering all the logic for my multiple displays setup.

I’m not sure what the high-level strategy is, but do note that there’s the

    move workspace to output right

and so on bindings to help out. I’ll typically keep a workspace as “whatever windows I happen to have put in it, over time” and then I’ll bounce them around to monitors as needed.

Roughly speaking, my Sway config:

- Assigns most apps to a specific workspace

- Assigns the standard hotkeys to focus specific workspaces

- Assigns a hotkey for Rofi to filter and focus apps directly

- Assigns hotkeys to move a workspace to the current output/display

- Sets hotkeys to move a workspace 1 output left/right

Now I can quickly bring the most relevant contexts for a task to each display, and can also quickly switch to another context and back as needed.

It's not perfect, but it's pretty good. I'd like some apps to be on multiple workspaces, for example. And I am exploring the idea of a way to search for and bring an app onto the main display as a centered float temporarily then dismiss it back to where it came from with a single key — for example to bring up a Slack channel front and centre, reply to a message, then quickly dismiss it again.

I may be misunderstanding your description, but isn’t this how macOS built-in spaces already work? I use this daily, and swap desktops with ctrl+left/right and the ctrl+num keyboard shortcut to get direct space switching (I have 4 for roughly the same purposes as you describe). When using multiple displays, I can even make each display have independent spaces.

It's exactly how it works but only if you have mutliple screens.

My comment was that, for this reason, 2 or 3 smaller (ish- ~27") 16:9 4k screens [1] (previously, 4–6 even smaller 4:3 screens) works much better for me because I can switch the spaces on my Macbook and i3/Sway virtual desktops on my Linux machine individually for each screen.

If we're talking about having a smaller number of giant screens it would need to be able to be partitioned into logical "zones" for virtual desktops to enable this way of managing sets of windows together, and I've not found anything that really does this, let alone does it well (though honorable mention to HerbstluftWM [2] which I think, with patience, could probably do something pretty close).

[1] preferably 16:10 but that seems to have died out as an aspect ratio :(

I'm in complete agreement with you. I use i3 (still using Xorg) and find the ability to have multiple desktops that I can move atomically between monitors to be far better than having to position windows individually. I put reference material, chat, etc, on the side monitor and then can very quickly move it back to the primary monitor when I need it. I find a normal 16:9 monitor to be just right for two side by side windows, or a tile of three, with one tall window taking half of the screen and two terminals top and bottom on the other side.

I hate using the mouse to manage windows, and having one huge ultrawide just feels like a nightmare to manage -- I'd need some way to split it logically into 2 or 3 virtual monitors.

With i3/Sway having the limitation of 1 workspace per monitor AND each app only being in 1 workspace, I could still use that logical splitting at times even on normal 16:9 displays.

I do this too. Main monitor has sets of desktops for “primary” tasks (e.g. IDE windows) while the secondary has several “auxiliary” desktops (one for email, one for chat, one for documentation, etc).

The ability to mix and match these between monitors is seriously powerful and basically eliminates window micromanagement and seriously curbs alt/cmd-tabbing. Everything stays put as switching desktops becomes the primary form of navigation.

Ain't that the truth.

The "top of the line" CalDigit docks are incredibly expensive and buggy.

...and they're on their 3rd or 4th iteration.

Plus not much competition, so not much choice either.

If I could go back, I would have also gotten a single ultrawide monitor.

Plus Macbook Pros multiple monitor support sucks relative to windows AFAIK.

Dell docking stations have been rock-solid for me (the laptop is also a Dell) and they can be had for quite cheap (about 50% retail) on eBay. I also balked at the price of caldigit units.

Be very careful about Dell docking stations. It's not always clear whether they're based on DisplayLink or real Thunderbolt/USB-C. The problem with DisplayLink is that a) you need a driver and b) after installing the driver, some websites don't show video (Udemy for example). This is on macOS, by the way.

Mine worked great with the Dell laptop on Linux ;) no drivers and video shows just fine. (Anecdata, I know)

At $work they had a variety of dell docking stations around the cube farm.

I use an old intel macbook running macos, and found that the docking stations with usb-c didn't support secondary video, while those with thunderbolt (usb-c with lightning bolt) worked fine for all docking station needs (secondary video, charging, USB keyboard / mouse / camera / etc).

A thunderbolt docking station and a 24 inch 19:10 monitor transformed my home office setup. Big monitor in portrait mode in front of me, macbook to left, old IBM M4-1 (trackpoint) keyboard, webcam perched on top right corner of macbook so I can have windows in either screen and it kinda looks like I'm still looking toward the camera instead of being rude.

I've found the biggest problem with the big monitor is where to put the video call camera -- if you're looking anywhere but toward the camera it looks like you're not making eye contact with the people on the screen and it seems "rude" because there's the impression that you're not engaged.

Ditto for Belkin docks. A Belkin Thunderbolt 3 dock can sometimes be had from $20 on eBay if you’re prepared to get one with no cables.

What's buggy about them? They've been pretty good to me.

In my experience CalDigit docks are really solid. The only issue I've ever encountered is caused by my laptop demanding more power than the dock will provide: when I hit a power usage spike sometimes my laptop will briefly drop connection with the dock, causing my display to momentarily lose signal.

This is easily fixed by plugging my laptop into a separate USB C power supply.

Same. I’ve had great luck with both the TS3+ and TS4. What few minor gripes I’ve had with them have been resolved by firmware updates.

It’s other brands, especially USB-C (rather than Thunderbolt) stuff that I find extraordinarily flaky.

I think you could daisy-chain DisplayPort MST monitors, so that only first one would be connected to your laptop.

Does anybody know how to test if a monitor is compatible with that? And is it plug and play?

My understanding is that, yes, it’s plug and play. If the monitors have DisplayPort out, they should support daisy chaining.

On windows and Linux this works great. I have two Dell business screens, one with USB-C, a DP in and a DP out. Just connect another screen to the DP out, and you get two screens over one USB-C connection. Together with the charging and USB hub provided by the screen this replaces a docking station for me.

However, Macs have spotty support for this. I believe it works on the newest Mac books, but not older generations, and not the Mac mini?

It doesn't work on Macbooks. References to macbooks supporting MST are about certain early high res monitors that behaved internally as multiple monitors due to bandwidth limitations on Displayport 1.2. That's fixed with higher bandwidth newer DP and HDMI revisions so the MST feature people care about these days is monitor chaining, and that is still not supported even in M2 Macbook Pros
