If you are using MacOS, I recommend these 2 apps<p>1. "Rectangle" for window management <a href="https://rectangleapp.com/" rel="nofollow">https://rectangleapp.com/</a>
2. "BetterDisplay" for better scaling quality on bigger screens, especially if you have a 4k ultrawide. <a href="https://github.com/waydabber/BetterDisplay">https://github.com/waydabber/BetterDisplay</a>
I have a 49 inch CRG9 and the best recommendation for window management is Yabai (<a href="https://github.com/koekeishiya/yabai">https://github.com/koekeishiya/yabai</a>) along with skhd (<a href="https://github.com/koekeishiya/skhd">https://github.com/koekeishiya/skhd</a>). Yabai is a greedy window management solution that tries to fit opened applications in given space and skhd let's you easily jump between those using keyboard shortcuts. This has massively improved my ultrawide experience.<p>Only disclaimer is, configuring yabai has a slight learning curve.
It provites great user experience in news web-sites if being used in vertical mode. News websites became greedy in receiving different kinds of activity from user (close cookie banner, close subscribe banner, close some video with overlay which fires after first scroll). And they love to give you nothing except header and few lines if you have not scrolled on your 1920x1080 monitor. But on vertical ultrawide it is possible to read most of the publication before giving any activity bits of my mouse to the webmaster and if the publication is not interesting I can understand it without reacting to the pesky AJAX features.
Definitely try out fancyzones from powertoys if you're on Windows. For Linux I'm not really sure, not much of a Linux desktop environment type, but I'm sure there's something for gnome. Lg makes a software I think it's called screen split, but fancy zones is better in my opinion. I run six 34 inch 2k ultrawides. I use the "edges" for stuff on the back burner - main content goes in the middle. It you have the right monitor some ultrawides can split inputs if you have multiple machines/ sources. That could be useful for dual os or work & personal setups.
The lenovo (and some other) ultrawide can be driven as two monitors butted side by side, which means you can scroll or pan halves independently.<p>Doesn't seem to work in OSX alas.
