Well, here I am full of warm and fuzzy feelings with my beautiful multi-monitor rig, and along comes my brother (the one who is not even an engineer!) and emails me a photo of his rig.
Nine monitors total. And he claims they are FDA approved to boot, in case you wanted to eat one. Also, you can see that he uses the exact same phone I use at my office, which doesn’t mean anything but I wanted to point it out. He’s a couple of screens shy of recreating his own Circle-Vision 360°, which is cool but is no Space Mountain (not even a Pirates of the Caribbean).
It is still unclear how many screens are driven by the same computer.
