Need help with stretched res

[StoCS]

Hey, I have a 21:9 monitor that has a native res of 2560x1080 what resolution do i have to use to get it stretched in fortnite. im not sure if the the regular 1440x1080 will work because my monitor is 21:9 2560x1080

Enter the un-stretched resolution, or else the FOV will be wrong

[StoCS]

wait what do you mean by that

[DPI Wizard]

If you play with 1440x1080 stretched to 2560x1080, enter 1440x1080.

wait what my native res is 2560x1080 i dont play with 1440x1080 i want to get streched so im asking what res to use

[DPI Wizard]

I though you asked what resolution to use in the calculator at first, now I see.

But what res to use depends on what you want to achieve. If you want to have the same stretch as 4:3 on a 16:9 monitor, 16:9 (i.e. 1920x1080) is the same amount of stretch on your monitor.

OHHH so basically what i have to do is create 1920x1080 as a custom resolution and use that and it will be the same as 4:3 strectched
