Fortnite Can't Change Resolution

[wolfiems]

Hello!
I can play 1920x1080 before the updates. Now I can't change my resolution in Fullscreen Mode. I changing to 1920x1080 and pressing "Apply" it doesn't change. It stucked at 1280x720 and it looks like so terrible.

I tried the Windowed-Fullscreen mode but it causes FPS drops , More Input Lag and has Low FPS.
I can't solve this.

I think it is a bug that they are working on. Try changing the screen to borderless
