Have you thought about VR? I’d say that’d be the way to go, especially considering a 3x monitor setup would run about the same as an entry VR headset. The big considerations are whether your computer is powerful enough to handle it and how likely you are to get VR sickness though. From my experience after trying VR I don’t think I could ever go back to playing immersive games any other way (sim racing or Digital Combat Sim)
