ok, here are screenshots .............
The (abv) is my FOV after selecting 3-1280x800 16:10 ratio in my "edit list mode" in my "Matrox-SE". Then selecting 3840x800 in my "SGU".
Notice the top of aircraft prop is at the top of the screen. Also notice that you can only see about half of the aircraft gauges at the bottom of the screen.
The (abv) is my FOV after selecting 3-1280x960 4.3 ratio in my "edit list mode" in my "Matrox-SE". Then selecting 3840x960 in my "SGU".
Notice the top of aircraft prop is at the top of the screen. Also notice that you can see the 1st row of aircraft gauges in their entirety at the bottom of the screen. This means it has a better vertical FOV right?
The only way I have access to 3840x960 in the SGU is by selecting 3840x960 4:3 ratio in my "matrox-SE" - "edit list mode".
Keep in mind that my monitors are 16:10 ratio monitors. But I am allowedable to select 4:3 ratio resolutions in my "matrox-SE utility.
I think IL2-1946 was originally written as 4:3 ratio and I guess this is why the FOV is better after selecting a 4:3 resolution in the "matrox-SE.
I guess my point to all this is to pass on information to matrox so maybe as to help them figure out a way for us to get a better FOV.
Above of course is the correct FOV for IL2-1946 using a single monitor.
