Compensating for something

I have nine monitors on my desk at work. That might sound like a lot, but it’s nothing compared to the setup that appeared on Lifehacker earlier today - an overcaffeinated day-trader in the States has set up a home office with forty monitors.

Here’s one-third of his setup:

So, I’m officially stumped: how the hell would anyone use forty monitors? I’m assuming he’s doing some sort of systematic trading mumble swerve, but there’s still no way that that takes forty screens. So what’s going on here? Anyone? Anyone? Bueller?
