TF2 PC - 4k resolution not showing in resolution options in video settings menu

I have the Same problem. Show native resolution 1920x1080 when my native resolution is 3840x2160. Its more i had problems to run the game for that at the beginning. I have a 55 inch monitor/tv and a nvidia 980 in my computer. I have the last nvidia Drivers 375.70

I cannot play above 2560x1440 either.  My display is 3840x2160 native.

Thanks for another scrub console port EA.  Love your work, as always.

My dispplay is 5760x1080  Triplescreen with NVidia Surround and it works like a charm for all other games including TF1. Only TF2 doesnt show me the menu when in 5760x1080. When scaling down I see the menu again.

So basicly EA * it up again after not supporting multiscreens in FIFA 15,16,17. 

So I think this will have been the last game I bought.

*ty console ports all the time.

I found a solution:

C:\Users\<Username>\Documents\Respawn\Titanfall2\local\videoconfig.txt

"setting.defaultres" "3840"
"setting.defaultresheight" "2160"

Works for me.
