Yes. 21:9. Not 16:9. My screen runs at 2560px x 1080px natively - a step up is 3440px x 1440px, but that monitor was too rich for my blood.
Several screens are looking good
Ok, stretched. It happens.
Everything with video has this stretched edge pixel effect. Back bars on full motion video is sort of par for the course, but I can hope you have a possibility on extending the scenes for playable interfaces.
If one of the developers wants to pick up a screen, sufficiently large computer store should carry at least one model by now. The cheap one is available at Haggerty & 8 mile, John R & 14 mile has expensive options. If you want to drive, of course *wonk*.
