Can't select any 16:9 aspect ratios. Stuck on 16:10

My monitor and desktop are at 3840x2160 (16:9). I know Big Pharma does not support that resolution so I would like to do 2560x1440 in fullscreen. However, while that is an option, when I select it the game goes to 2560x1600. When I try any other 16:9 ratios, it displays the closet 16:10 instead. I have tried changing the config file to 2560x1440 with no success.

Hi abiobob, I replied to your Steam forum post. Did you see it yet?
