Lol. Individual monitors in Portrait mode arranged in landscape.
The third one from the top.
That's a seriously dodgy picture. In the 6 screen version the monitors are stupidly wide (i.e much wider then 16:9). In all of them the middle monitor is significantly wider then all the others. Note: it can't be because the outer monitors are angled because the image would show it (ie. any diagonal line going from one monitor to the next would have a noticeable change in angle if you had angled outer monitors).
Also the game will either maintain the vertical angle (in which case uber wide screen see the same amount vertically as everyone else but then have a much wider horizontal fov), or horizontal angle (in which case uber wide screens get the same horizontal fov as everyone else, but loose out big time vertically). Those screen shots do a mixture of both.
It also doesn't help that they are all drawn to different scales (so for example the 3 screen one has much larger monitors then the others).
