When launching a session from UEFN on a monitor set to 2560x1440, Fortnite appears to launch at 1920x1080 in a small window in the middle of the screen. The resolution and display mode cannot be changed correctly while the UEFN session is running.

Steps to Reproduce
Use a monitor that supports 2560x1440 resolution
Set the monitor and Fortnite resolution to 2560x1440
Open a UEFN project
Launch a session
Wait for Fortnite to open
Observe that Fortnite appears to launch at 1920x1080 in a small window in the middle of the screen
Open Fortnite’s video settings
Attempt to change the resolution or display mode to Windowed Fullscreen
Expected Result
Fortnite should launch at 2560x1440 and allow the resolution and display mode to be changed normally during a UEFN session.
Observed Result
Fortnite appears to launch at 1920x1080 in a small window instead of using the monitor’s 2560x1440 resolution.
Changing the resolution or setting the display mode to Windowed Fullscreen does not apply correctly while the session was launched through UEFN.
The issue does not occur when Fortnite is opened normally.
That’s due to settings on the UEFN. You can even change the resolution if you want, but I also don’t like it and it does not let us change dynalically to test different ratios/fulscreen/windowed and resolutions after launching the game through UEFN which limits a lot.
I constantly need to close the game, close uefn, then relaunch game first then uefn later just to “avoid” that forced behavior…
Imo they should add an option to not “force” it to anything (Currently it is always forced without option to be “neutral/disabled”)
This should definitely be an option, not an EITHER/OR functionality(I don’t want full screen 1920x1080 on a 55" 4k screen, and no reason to render FN in 4k and the editor in 4k). Personally I find it much easier to switch back to UEFN to make edits while the game is in 1920x1080 and is a smaller rectangle instead of stretched across the entire screen(takes focus from all other processes until alt-tabbed to).
I’m also generally watching youtube while working/testing so the game taking up the full screen is undesirable for me, often times the game will go to sleep in the background until I’m ready to test once more, so again, no need to use extra resources unnecessarily by rendering the game, and editor in 4k(or jumping through hoops like lowering my desktop/game resolution), whilst also blocking my youtube viewing.
