This is a copy of the my comment on the DX:MD page and it was suggested to seek support here as well. I would like to know is there is a way to get 32:9 (5120x1440) to work without black bars? I tried editing the executable with HxD and also tried search for the aspect ratio with cheatengine to adjust the known values but nothing seems to work.
Furthermore, why does the article show green for ultrawide, even though it doesn't work?
