Dota2 doesn't have 21:9 aspect ratio?

[Solo Leveling]

What's up guys, how we doin' ? I really need your help.
I just bought a MSI Optix MAG341CQ Ultrawide Monitor and the best video setting I could find in the game is a 16:9 aspect ratio and 1920:1080 100Hz resolution. The view experience with this setting isn't great!
Is there any way to get a 21:9 aspect ratio and a 3440x1440 100Hz?

Are you sure you've set right resolution in Windows settings?

You can set your resolution by using launch options.
Go to Library => Dota 2 => Properties and in the input bar write this: -h 1440 -w 3440

I have -h 1440 -w 3440 in launch options but 21:9 aspect ratio still unavailable

that would be unfair advantage (as the zoom..) ? or it isn't?
