Not sure why this isn't sticky. What you want is Windock and completely free.
Then import this json for a 60/40 split.(create a notepad, paste rename json extension. Play around with it for your triple setup.
{"name":"21:9 60/40","rules":[{"dock":{"monitor":0,"values":[0,0,100,100]},"trigger":{"monitor":0,"pos":"bottom","type":"edge","values":[0,100]}},{"dock":{"monitor":0,"values":[0,0,60,100]},"trigger":{"monitor":0,"pos":"left","type":"edge","values":[0,100]}},{"dock":{"monitor":0,"values":[0,0,60,100]},"trigger":{"monitor":0,"pos":"top","type":"edge","values":[0,60]}},{"dock":{"monitor":0,"values":[60,0,100,50]},"trigger":{"monitor":0,"pos":"right","type":"edge","values":[0,50]}},{"dock":{"monitor":0,"values":[60,0,100,100]},"trigger":{"monitor":0,"pos":"top","type":"edge","values":[60,100]}},{"dock":{"monitor":0,"values":[60,50,100,100]},"trigger":{"monitor":0,"pos":"right","type":"edge","values":[50,100]}}]}
Just as a balance to /u/Hubb1e's comment: messing with windows is easily fixed with a little program called WinDock, which lets you easily create default profiles for window sizes (on my 35" 1440p UW I can do four full-size word documents side by side, for reference). As for game support, it's not always perfect but the vast majority of games support UW by now or at least have a WidescreenFix. Even for those that don't support it properly and just stretch a regular 16:9 image to 21:9, I still prefer that over regular 16:9 any day.
EDIT: Oh and reading further on in the thread I see there's some debate on the value of G/Freesync. As for my 2c's: it is absolutely worth it. I've had cases where my framerate was fluctuating between 50-80 FPS and I barely even noticed it (other than the number in the corner of my screen changing, obviously). It's one of those things that just "seems neat" if you've never used it before, but once you have it you'll never want to do without.
Thanks!
The window snapping is done by a small program named WinDock! I adore it, it's become one of my favorite programs ever. You a drag a window to a specified location (edge, area or corner) and it'll snap into any size and position you have specified. http://www.ivanyu.ca/windock/
The icons in the middle of the taskbar are done by right clicking the taskbar > toolbars and adding something. Drag that in front of your icons and you can place them wherever on the taskbar. It is a little fidgety but once you know how to do it it's easy. Probably handy to follow along to this video: https://m.youtube.com/watch?v=ONxw2PdjRhw
Good luck!
>Is there a way in Windows or the on screen menu to "format" your display. What I'd like for example is to have the screen treated like 2 screens. So if I have a browser on the left and I hit full screen, it will fill just the left. And I could also drag a window to the right and have it snap to the other side of the screen.
I use Windock. You can set up custom regions on the screen for windows to fill, and then set custom triggers for how to activate them. I have one on the left and one on the right for two browser windows, at about a 60:40 split.
You definitely want to check out Windock, it should suit your needs quite nicely.
And if your interested there is another program called Aquasnap. It's a similar program with some different features like shift clicking the edges of a window to maximize it in that direction, and magnetizing all window edges.
I run both and disable Aquasnaps snap feature since Windock's is better. They also both conveniently run on startup :)
I work fairly often on my PC (I'm a developer), and I can't stand working with 1 screen only. But this actually works out, and my even be better than multiple monitors.
Screen is large enough so you can have multiple windows docked and they'll still be big enough for you to be comfortable.
I downloaded Windock which is brilliant to dock and manage different layouts and profiles.
Also, as you see, multi monitors is not an option for me here. Desk is too small.
TL;DR
Multi tasking surprisingly feels (almost) better than on multiple monitors.
Not sure if it's just a typo in your comment or not, but he said it was "windock" and you said "windlock" with an L in there. Looks like this is what he was talking about
I'd recommend WinDock (http://www.ivanyu.ca/windock/ its free) to manage your desktop space, it's not the most intuitive (that said its not overly complex either). I have mine set to snap the screen into 3rd's virtually (by dragging the window to the top of the screen where you want it snapped) and 1/2 screen windows by dragging them to the sides of the screen, I also have 2/3 and 1/3 window sizes setup along the bottom, it works amazingly well. I thought I'd struggle going from dual monitor to a single UWS but its actually an improvement.
I've got the same monitor since december and I love working (I'm a full-time software-developer) with it using http://www.ivanyu.ca/windock/ and gaming on such a big/wide screen is awesome... the sad thing is, that nvidia shadowplay doesn't work with those high resolutions (3840*1080) as it's recognized as a sourround setup. I hope they'll fix that soon. (Also streaming is a bit odd since viewers with a standard aspect ratio got a black letterbox top and bottm of the video)
If you can resize those applications, you can try WinDock: it's a flexible window docker, just set a position to drag your window and the resulting size (ex: Trigger: Top Left Corner; Position: Left 0%, Top 0%, Right 50%, Bottom 50% --> dragging a window to the top left corner will resize it to the top left quarter of your screen).
Now, if you can't resize the windows, maybe try this: https://www.howtogeek.com/howto/11799/turn-non-resizeable-windows-into-rezieable-windows/
There are two options I've tried, one being Windock: http://www.ivanyu.ca/windock/ and the other being the native Screen Split driver for my LG ultrawide, not sure if that can be used for other monitors though.
Check these David Zhang videos... on how to setup an ultrawide for programming/coding and references. Both video are pretty good to help to organize the windows. If you don't want to buy display fusion, try Windock it is one the best window management I have used so far.

First test of this software (windock) and it seems to be a good start, custom drag to snap areas with custom window sizes.
Doesnt look like keyboard shortcuts are allowed, I'll keep searching though.
WinDock looks pretty cool, thanks for sharing it! Does it allow you to save super-specific window layouts that everything will automatically load to?
Also, 16:9 portrait + 23:9 landscape, right? If so, you're the only other person I've seen match my setup! (I don't have any pictures up, my desk is far too messy for that...)
I was originally planning on using it in portrait (I picked up a used stand with swivel) but I found that it was limiting what I could easily send over to the secondary screen.
If I had a job that required documentation or websites open constantly I would probably keep it in portrait, but for my more mixed usage I've ended up just keeping them both landscape.
I do use the nice little Windock utility that someone here on Reddit posted which sort of replaces Snap and easily makes windows take up halves/thirds/quarters of each screen (if anyone knows of something with hotkeys too let me know!).
