21:9 Ultrawide cut-scenes have black bars. Fix?

[ben]

Hey so I'm running the game on a 2560x1080 monitor. Everything except the cutscenes work fine. Anyone know of a tweak to remove the black bars on the sides?

Taken from pcgaming wiki directly. Old but like to help out people who stumble on stuff albeit sorry for necro: "You may need to manually add resolutions wider than 16:9.
1. Edit %USERPROFILE%\Documents\BioWare\Dragon Age\Settings\DragonAge.ini
2. Change ResolutionWidth= and ResolutionHeight= to the resolution you want."
