Man, I don't even bother using the ultra-wide monitor on my desk. The screen on my laptop can already display orders of magnitude far more information than I can easily process at one time. Even with contexts where I'm comfortable managing windows/buffers manually (e.g. emacs) there's simply too much space to easily manage. What do you do with all that space? Is it just pulling up every possible resources at once so you don't need to bother doing anything more than moving your eyes to switch contexts? How often are you switching contexts?
