Every other example use they've picked seems designed to make it look like it has a bezel with no content crossing the middle of the screen - this single counter-example is buried.

The "ergo stand" photo actually had me fooled for a while--the "ghosts" just show you different ways the one giant monitor could be positioned.

A 2x(16:9) configuration where the monitors could be brought really close together would be neat though...

I have one- I can confirm, no bezel. It's just a single contiguous panel as far as I can tell. I does have software support for feeding 2 inputs into the top/bottom, but by default it just hooked up as a single monitor. Looks great!

Even that image is a little confusing; the strong red/blue line in the middle made me wonder if there was a seam between two panels. The red sugar packet on the left is the only thing that unambiguously indicates it's a single continuous panel.
