21:9 aspect ratio

21:9 no support at all? i have actually an ultrawide ips monitor to play, it's amazing how it looks but videos just go to 780p as you were in a 24" monitor and effects like when a police car begin to chase you flash but only in the middle, rest of the screen seems unchanged, it's more a annoying issue, have you 21:9 screens supported? if so, can you check the effects on this screens?

Thx.
