2560x1080p 21:9 looks fine
3440x1440p 21:9 looks weird
3440x1451p 21:9 looks fine
5120x2160p 21:9 looks fine
There's no exact 21:9 ratio, heck even 21:9 isn't what either of the displays actually is:
21:9 = 2.33333333333
2560x1080 = 2.37037037037
3440x1440 = 2.38888888889
The term "21:9" is just a made up marketing gimmick for anything approximating a CinemaScope ratio, which itself has varied through the years from between 2.35:1 to 2.40:1.
The good thing is, any game that plays well at 2.37:1 plays just as well at 2.38:1. I don't doubt that we will see additional minor variations in the aspect ratio when larger resolutions come out.
So far, the manufacturers (and by that I mean LG, since they are the only 21:9 desktop panel maker as far as I am aware) seem to be re-purposing existing 1920x1080 and 2560x1440 production, just with a wider horizontal resolution on the mother glass substrate. Which is why I wouldn't be surprised if the next logical step is a 3840x1600 (2.4:1 ratio) panel. Either that or a 5120x2160 (back to 2.37:1).
Speaking of, were you able to get a resolution of 5120x2160 working? I haven't been able to get anything wider than 3840x1620 to work properly.
