BioWare generally stops supportign games a year after the initial release, which is where we are now. They also don't have any official support channels, but they do have a feedback forum here: http://forum.bioware.com/forum/329-feedback-suggestions/
Sadly, BioWare's concerns are more towards console gamers nowadays. The game had some glaring PC specific issues at release, some of which they fixed, but many issues are still in the game. They even released a PC specific featurette before the game's release that I think they ended up regretting because of how dishonest it was. Another example is Mass Effect 3 where the HUD doesn't scale to resolution, which means any resolution that isn't 1280x720 has a user interface that doesn't have the correct size. This makes subtitles nearly impossible to read at high resolutions, even if the game natively supports them.
There is a mod called Flawless Widescreen that has configurations for many video games. The Dragon Age Inquisition plugin fixes cutscenes and DirectX crashes for triple monitor users, but not the behavior menu issue.
