also you can use "displays" table  to perfectly match you configuration .
it is generated by DCS automatically.
displays table is contains information about all currently attached displays

for example my setup is :

displays =
{
    [1] =
    {
        x = 0,   -- note : x == 0 and y == 0 is always mark primary windows display
        y = 0,
        width  = 1920,
        height = 1200
    },
    [2] =
    {
        x = -1440,   -- mark that secondary display is on left side of primary display
        y = 0,
        width  = 1440,
        height = 900
    },
    ...  for all displays
}

screen table also contain x, y members which mark top left corner of DCS window

note about fullscreen :  directx  doesn't allow fullscreen applications with resolutions more than primary display can handle,
so multimonitor presets in DCS will fall back to windowed mode if fullscreen initialization failed  ( this info also will be printed to dcs.log)

for reconfigure viewports setup for each unit type independently you can declare here function

function  reconfigure_for_unit(unit_type)   --unit type is string with unit name
    if unit_type == "A-10C" then

        Viewports  = ... define new Viewports table
        -- also you can define cockpit displays viewports here
        RIGHT_MFCD = ... define new RIGHT_MFCD  viewport

    else
        Viewports = ... define default for others
        RIGHT_MFCD = nil  -- remove for others
    end
end
