They have a demo on the site of how multiscreen works. It's a past race that you can play around with. You can do picture in picture, four screens at once, and all sorts of other combos. You obviously pick what you want on each screen. All on the same tv/monitor. You are allowed unlimited logins from the same IP as well so you can also pull up different camera views on a completely different TV/monitor at the same time. Not sure if that is a multiscreen only feature or not.
