Stuck at 1920x1080

[WAY too many wasps]

Hi, I'm having issues trying to swap my resolution from 1920x1080 to 2560x1440.
I've been eagerly awaiting this game and would like to see it in its full glory on my 2560x1440 monitor.
However, the options for 2560x1440 and above are greyed out, no matter if I'm in borderless windowed or normal windowed. Fullscreen is seemingly not an option.
Please help!

Also yes, I did install the newest drivers and turn off DSR. What now?

Perform a clean install of the driver perhaps?

I have it listed using my 4k tv, so it does support it.
