(2) Dell 27" monitors in surround mode no bezel correction?

Hello,

I have 3 Dell monitors as follow;

1- U3014  30" exclusively for work.

2- U2713HM 27" for flying FSX and P3D (no games ;-))

I connected the 2 27" in surround mode to GTX780 card but could not make use of bezel correction from NVIDIA control panel.

I dug out my old TH2Go digital, installed and bezel correction grayed out as well.

searching the net reveals that surround mode not supported by any party due to centering problems with most of the games (aiming cross and some other things will be covered) and they elect 3 monitors, but FSX and P3D can handle this centering issue because that is where windshield center support bar is on most of airplanes and have no problem on the general display.

Is there a way other than official software for nVidia and Matrox that I can use to resolve the ugly mid bezel problem?
