Home office has a single ultra wide plus my laptop screen under it. Work on the big screen, YouTube and teams on the laptop.
At work I have an ultra wide with a 16:9 portrait display (turned 90 degrees) on the side. That leaves the big space for work, and the side one for teams, YouTube, and any documents I have to reference.
First time using a portrait display, and it is so much nicer for reading PDFs and the like.
