Overview
3440x1440 (21:9) is natively selectable and works cleanly out of the box, including cutscenes. 5120x1440 (32:9) is not offered in the resolution list, but it's a straightforward one-time fix: edit ResolutionSizeX/Y in GameUserSettings.ini, and the fleet-command HUD and menus render correctly across the full panel afterward. Blackbird's 1.3 update (their last major patch) didn't add 32:9 to the official list, so the ini edit remains necessary.
