BF4 just won't play nice at 21:9

[Nuwidol]

Having an issue getting BF to display correctly at 3440x1440.

I just get a massively zoomed in 1280x720 of the top left corner.

I've attached 2 screenies. One of my settings & one of what these settings give me in full screen.

I've tried changing the ini file (or whatever its called) & all the possible scaling options in nVidia control panel. Game displays fine in 2560x1440 & BF3 displays fine at 3440x1440...

Really stuck as to how I can fix this..

Any help appreciated.

Try this: Borderless windowed, then spread it.

Like this:
- Set your in-game resolution to what looks right, I think you said 2560x1440.
- in game settings to Borderless.
- Download ShiftWindow & use this program to spread & position your Borderless window. The pixel count should increase right & not stretch. Effectively looks like fullscreen, if you enter the right numbers. (I think the right numbers for this game must include the pixels of your border also. This will push game right out to edge of screen)

This trick works for spreading game well in PLP. So likely will work for you. Good luck.
