Interesting perspective. You could very well be right. That said, when people talk about multiple monitor setups, my hunch is they want to see all of them. After all, if you have a three monitor setup on your desk, most likely you’re using all three together, dragging windows between them, putting your active document on one and palettes on another, etc.
Yes, but even there, if everything on say a virtual quad screen is not updating at the same time, there could be enough bandwidth to update all of them.
A very typical example would be the stock trader setup. He/she may have 4, 6 or 8 screens in front of them, each showing a chart of a single stock with maybe some news feeds about each stock. In real-time trading, very little on all of those screens is updating. A bit of new news on screens 2 & 6, a tiny vertical sliver at the far right of the charts for "right now" price data updates, etc. All of that should easily fit into the available bandwidth.
At the other extreme, imagine the NFL Sunday Ticket fan with 4-8 TVs set up to live stream all of the games in 4K at the same time. Attempting to replicate live 4K video streaming to 4-8 screens with no screen tearing, etc due to pinched bandwidth would likely NOT be possible... UNLESS the heavy lifting was done in some attached Mac for such a purpose that then renders the Vpro view as a single 4K stream... a virtualized, virtualized view if you will. Then, it's still one 4K stream being fed to Vpro but now it looks like the usual view of Vpro... akin to how the Vpro interface might be rendered on a 2D screen for app programming purposes.
My best guess: I see the stock trader scenario working just fine since even 8 screens wouldn't actually need that much data flow to keep updating. I'll guess that multiple streams of complex 4K video playback doesn't fly. But that's wild guessing. We'll have to wait and see what it can actually do in person.
Personally, I'll be quite thrilled if it delivers very high res view of a single MB screen at a much larger size... exactly as demoed in the WWDC video. The cheaper options can already do this at low resolutions, so it seems highly likely that Vpro will do this much better at higher resolution. Using a MB with a 50" screen when on long flights, etc is very appealing to me.
