I don’t think 3 monitors qualifies necessarily as “too many” under what I was saying before - I also have 3 monitors, one ultrawide and two portrait monitors on either side. I can see everything I need with only miniscule head movements, and I make a point of keeping my main focus work on the center display, to avoid neck strain.
My point there was directed mainly at the people who want VR workspaces so they can be surrounded in a sphere of monitors
