I had three hits at 3820x1024 resolution. What the heck is that, a wide screen TV?
No, even the widest screen available is like 1080i, which runs at 1200x1080 interlaced. I'd guess its someone with three monitors running side by side, since the numbers almost compute. Since google brought up several game related multimonitor sites, I'm gonna guess that's the case. Which means, that you're basically working with a 1280 x 1024 screen, since splitting that up would make your page a pita to read.
