I tried to do some flying with two monitors. It 's really a different look, the vision is wider and there is a greater feeling of being in the cockpit. Too bad that ... Vista once again shows less efficient than good old XP. With XP it was possible to have the direct configuration of the use of double or triple monitor using ATI or Nvidia drivers, but both manufacturers have not updated the drivers for this feature in Vista and I tried if there was any ploy to circumvent the problem.
course the easiest is to spend and buy a pat € the Matrox TripleHead2Go (digital version, the analogy does not work on Vista). On the Internet, the alternative could be UltraMon which allows you to actually install and configure the span across two monitors, but not with FSX, or rather the working span on the 2D monitor, but not on the virtual cockpit and landscape (I think that part of the blame is to be assigned to directX). And then you just have to open two windows, each on a monitor, and try to match the images to give a feeling for enlarged view. Sure, it works, but every time you move the image realignment is a painstaking work.
