Mirrors Edge resolution problem

[MilesTeg_cy]

Hi,

After a few years I wanted to play Mirror's Edge and made a fresh install. At 2560x1440(monitor's native res.) when I press "apply", resolution goes down to a very low level. I can play every other game with this resolution without any problem. I've changed the resolution manually from the .ini file but still the same. It is playable at 1920x1080 but won't change to 2560x1440. Need help please

Thanks.
