3080 4k monitor but highest resolution shown is 1920x1080

Title says it , Either on full screen (Displayport) or window windows/bordersless the highest resolution show in the option menu is 1920x1080 how can i fix this?

The update should be available in a few minutes. Install it and try again.

I’m facing the same issue. Running with a 1080ti. Game files appear to be updated/there is nothing to download. Is there a solution?

Same issue here.

Did you change setting to full screen or borderless full?

Yes. Went back and forth etc, no change. What I did notice is when I used a different Display port slot in my tower, I then saw the 2k option in game. but after reboot it went back to 1920x1080.

I had an fix, resulting me removing my beamer from the windows hardware profile. No it wasn’t even connected and the cable wasn’t even connected. Windows showed also 1 monitor present. I had to remove the beamer from windows hardware to get 4k in this game.
