Is it possible that my resolution only changes for a program / game? (Fortnite)?

Is it possible that if I open Fortnite my resolution changes from the monitor to 1440x1080? Have already created a resolution of its own, but I do not want to manually activate / deactivate each time is it possible that I set so when I open Fortnite that changes my resolution from the monitor to 1440x1080?

Srell the resolution in the game options

You can set it in the settings of Fortnite, just I do not know if fortnite this resolution has

Since I can only play at the normal resolution 16: 9/16: 10 but 4: 3 games

No, she does not have to manually change the resolution

May I ask why, a narrower field of view is rather a disadvantage, right?

Achso okay that is stupid. I think it should be adjustable in special files. Do you have to google this time, Ehm this is used on for more fps.

In that case not because the players are displayed larger

Xrandr -s 1440x1080

but only works with Linux.

Have windows.
