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

wait what do you mean by that

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

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
