For a long time I loved having 3 separate monitors. I liked the clear distinction between them and each monitor was used for a specific purpose.
A few months back I replaced them all with an ultra wide after discovering Windows Powertoys, particularly Fancyzones.
This allows you to divide your screen up any way you want, with or without gaps between windows, it’s all fully customisable. You can then snap applications into the zones, and it remembers where you last placed the application so the next time you open it, it will open in the same place. Essentially behaving like separate monitors.
You can also create shortcuts to flip between ‘grids’ so depending on what task you want to do on your PC that day, you can instantly have a different layout of all your applications.
This was the gamechanger for me and I love my widescreen now. The downside is that I have lost some screenspace, as widescreens are smaller than 3x monitors. However, I found that my neck doesn’t hurt after long use because everything is in my peripheral vision now.
TL’DR, get a widescreen and Windows Powertoys.
