Matrox Triplehead analog/Digital

After owning the Matrox Analog unit, and moving to the new Digital model, my sim planes fill the entire screen across all three monitors leaving me very little panoramic view as if I were directly behind the tail of the aircraft. The Analog Unit gave a very wide field of view, showing the aircraft out in the distance a bit. I'm running three 19" monitors set at 3840X1024 resolution. Any idea's about setting's I should be using? Thanks, Radialhead
