Updates shuffled my displays, need help with triple screen setup

[bumblebomb]

NVidia 3090, 3x 1920x1200. 

Until recently my middle screen happened to be screen 1 (  [2][1][3] ) which accidentally worked for DCS with a 3 screen setup. 

Now I struggled to get it right, my old config was this, with _no_ nvidia surround (I don't want NV surround for various reasons, one annoyance is the chat and server messages moving to the outer screens, can be fixed, I know, but once I switch back from surround I have to re-enable the monitors and check if they come back alright, re-arange all windows, thank you MS)

 

_  = function(p) return p; end;
name = _('1 big');
Description = 'One monitor configuration'
Viewports =
{
     Center =
     {
          x = 0;
          y = 0;
          width = screen.width;
          height = screen.height;
          viewDx = 0;
          viewDy = 0;
          aspect = screen.aspect;
     }
}
--GU_MAIN_VIEWPORT = Viewports.Center

UIMainView =
{
x = 1920;
y = 0;
width = 1920;
height = 1200;
}

GU_MAIN_VIEWPORT = 
{
x = 1920;
y = 0;
width = 1920;
height = 1200;
}

Now after the update Windows says my screen order is [1][2][3], so matching the physical setup (nvidia thinks otherwise for reasons beyond me)

I tried setting both "x =" to -1920 which sort of worked but now all main action happens on the left screen, including the Jester wheel, which makes the F-14 unusable. 

I just learned there is appSettings.lua as well which recently got new features, so long story short if someone could show me the ropes here I'd greatly appreaciate.
