I don't know if you use Ecran- wide mode if you did and you still get black bars you may have other problems. but Il2 as default doesn't support wide screen! and you have to edit some class files to do it compatible with wide screen support!(it is done in Ecran- wide mode) otherwise you will have vertical black bars.
You have to do as you done with your config.ini ( just add width and height you don't need to change SaveAspect=0 to SaveAspect=1) change EnableClose=0 to EnableClose=1 and install Ecran-wide mode if you didn't.
