Any ideas how to remove screen borders for 2560x1080 mode? 2560x1080 is selectable but stuck with black borders left and right????

Set the resolution to your monitors resolution/aspect ratio to avoid having black bars.

I have set the resolution to 2560x1080, the monitor is 2560x1080, the game still displays 1920x1080 by the looks of it. Cant seem to find any manual adjustment in the config files either.

the game uses the Unreal Engine, so you have to edit some ini file to get the rigth FOV. Sadly the Unreal 3 Engine is a b*tch to setup for special Res like yours. You may hav to do some google for the details

you could try to use this: https://www.flawlesswidescreen.org/
was the solution for my 16:10 screen… its very easy to install.

It also works for 5:4 (1280x1024)!
