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.
